Abstract ：
Sliding bearings are a key component of bridges, and their normal performance is an important prerequisite to ensure traffic safety. To solve the problem wherein a single type of sensor has difficulty in effectively predicting the wear life of sliding bearings, this paper proposes a method to predict the sliding bearing wear life using the multitype monitoring data of the bridge. This method uses the vertical acceleration data of the girder with high sampling frequency to calculate the bearing cumulative dynamic displacement under vehicle load and then processes the data collected by the longitudinal displacement gauge with low sampling frequency to extract the bearing cumulative static displacement under the effect of temperature. Next, the daily bearing cumulative displacement calculated by adding them is taken as the evaluation index, and the sliding bearing wear life is predicted based on the reliability analysis. Finally, the proposed method is verified by a numerical example of vehicle-bridge interaction and real bridge monitoring data. The obtained results show that the proposed method can be used to estimate the bearing cumulative displacement with high accuracy and can effectively predict the wear life of sliding bearings. The prediction results can provide an important reference for bridge evaluation.

Abstract ：
RC double-column medium height bents (DCMBs) are widely applied in the mountain areas as the substructure of highway bridges, and the two columns are normally connected by RC link beams to enhance the lateral stability. However, serious damage and/or large residual displacement were repeatedly observed in the DCMBs after many major earthquakes, which may make the bridges lose functionality and have to be demolished and rebuilt. In order to improve the seismic performance of the bridges, a novel self-centering variable friction dissipation brace (SCVFB) using SMA plates is developed to replace the traditional RC link beams in the DCMBs in this study. The mechanical properties of the shape memory alloy (SMA) plate were investigated experimentally. Then, the analytical model of the DCMBs with inverted-V SCVFBs (DCMB-SVFB) is built, and the corresponding design philosophies of the SCVFB in the DCMB are proposed based on the concept of structural fuse. Subsequently, the hysteretic behaviors of the DCMB-SCVFB in the transverse direction are analyzed, and the dynamic responses of the whole bridge under near-field ground motions are also investigated. For comparison, the seismic behaviors of the bridges with original bents (the bridges with and without link beams) and the bridges retrofitted with buckling restrained braces (BRBs) are also presented. The results show that the SCVFB has stable energy dissipation capability and excellent self-centering ability, even without the need of prestressing. Compared with the original bridge, the bridges with SCVFBs and BRBs are featured by higher strength, larger stiffness, better energy dissipation capacity, and less damage. In particular, the SCVFB can effectively reduce the residual displacement of the bridge and quickly restore the traffic capacity.

Abstract ：
Connections between prefabricated concrete panels (PCPs) are susceptible to cracking and damage, attracting the attention of bridge engineers. Curved bolt connections have ideal flexural performance when they have an appropriate anchorage distance. High-performance materials, such as ultrahigh-performance concrete (UHPC) and carbon fiber-reinforced polymer (CFRP) bars, bring solutions to further reduce construction resources on-site and improve the durability and mechanical properties of curved bolt connections. In this paper, curved bolt connections with UHPC grout and CFRP tendons (UHPC-CFRP connections) for PCPs were proposed. Prediction models for the flexural capacity, cracking moment, and deflection of UHPC-CFRP connections were proposed. Full-scale flexural tests were carried out to study their working mechanism, and their flexural performances were compared with those of ordinary curved bolt connections. Three-dimensional finite-element numerical models were developed, and the influences of important design factors on flexural capacity were discussed. Both experimental and numerical results showed that the flexural behavior of the PCPs with UHPC-CFRP connections is more desirable than that of curved bolt connections with ordinary materials. The improved models are effective for predicting the flexural response of PCPs with UHPC-CFRP connections.

Abstract ：
Shape memory alloy (SMA) as a high-performance material with intelligent properties, has been recognized as a promising alternative solution for achieving self-centering of the structure. In this study, based on the excellent characteristics of SMA, SMA L-shaped plate was developed and applied to install on the rocking interface of the rocking column to enhance the seismic resilience, and the seismic performance of the self-centering rocking columns with SMA L-shaped plates was investigated through experiment and numerical simulation. To this end, the mechanical properties of SMA plate were firstly investigated experimentally. Then the quasi-static cyclic loading tests of the rocking column with SMA L-shaped plates were carried out, and its hysteresis behavior was investigated under different loading protocols with varying displacement amplitudes. For comparison, a rocking column with steel L-shaped plates was also tested. The experimental results showed that the rocking column with SMA L-shaped plates exhibited excellent flag-shape hysteresis behavior with satisfactory self-centering ability and stable energy dissipation capacity, and owned a large deformation capacity. Subsequently, the dynamic responses of the self-centering rocking column with SMA L-shaped plates were investigated by numerical simulation. It is found that compared to the steel L-shaped plates, the SMA L-shaped plates can effectively reduce the residual displacement responses of the rocking column and quickly restore to normal operation.

Abstract ：
Reinforced concrete (RC) single-column piers (SCPs) and double-column piers (DCPs) are widely used in highway girder bridges. However, the seismic behavior of conventional RC DCPs has not received sufficient attention. This study aimed to investigate the seismic behavior of DCPs, especially the comparison of the failure mechanism, hysteretic behavior, and dynamic response between SCPs and DCPs. To this end, the critical performance parameters between SCPs and DCPs in the elastic phase were first calculated according to the simplified calculation formulas. Eight 1/3 scaled SCPs and DCPs were then fabricated and tested under quasi-static cyclic loading, and the effective height of the DCPs was twice that of the SCPs. The test results showed that the failure modes and damage mechanisms between the SCPs and DCPs are obviously different. In particular, the plastic damage states at the top and bottom of each column in the DCP were asymmetric, and this behavior was also observed on both sides of each plastic hinge region. Subsequently, the relationship between the performance parameters of SCP and DCP in the plastic phase differed from that of the elastic phase and was not proportional. Existing formulas for calculating the plastic hinge length of SCPs cannot effectively predict DCPs and may even underestimate it. Furthermore, numerical simulations were analyzed to investigate the effects of various design parameters and ground motions on the seismic behavior of the SCPs and DCPs.

Abstract ：
The traditional reinforced concrete canopy using cast-in-place (CIP) technology, is associated with problems such as long construction period, high environmental pollution, and low construction quality. Prefabricated assembly technology, due to its modern and highly industrialized characteristics, provides a promising solution to address the mentioned challenges. In this study, an innovative Ultra High-Performance concrete (UHPC)-filled grouted corrugated duct connection (UGCDC) approach was introduced for prefabricated canopy beam-column joints, considering the structural characteristics of the canopy. To evaluate the seismic behavior of canopy beam-column joints utilizing the UGCDC method, three comprehensive full-scale quasi-static experiments were conducted. Meanwhile, relevant seismic behavior indexes were extracted from the hysteresis curve, and the seismic performance of canopy joints was assessed by analyzing the effects of different research parameters on seismic behavior indicators. In addition, based on the OpenSees platform, a fiber finite element model (FEM) was established that incorporated the bond-slip behavior at the UGCDC joint. The research results indicated that the seismic behavior of canopy beam-column joints using UGCDC is basically consistent with that of CIP joints, and setting a shear key in UGCDC joints can improve ductility by 22.4 %. In terms of bearing capacity, there is not much difference among the three specimens, but in terms of initial stiffness, the specimen using UGCDC and shear key and the specimen using UGCDC have increased by 6.0 % and 9.6 % compared to CIP specimen, respectively. The developed FEM can predict the hysteresis characteristic of canopy joints using UGCDC. UGCDC method is a reliable connection form for canopy beam-column connection joint, which is suitable for medium to high intensity earthquake areas. Finally, a seismic performance assessment method of prefabricated canopy beam-column joints using UGCDC was proposed.

Abstract ：
The socket connection method is widely used in precast column, particularly in seismic regions. However, reducing the socket-depth to lower costs may lead to shear failure in the socketed part of the columns. To address this issue and achieve cost objectives, a new approach combines shallow sockets with corrugated pipes for column-footing joints. Comparative tests were conducted to investigate failure in columns with socketcorrugated pipe connections (SCPC), shallow sockets (SSC), and cast-in-place (CIP). Furthermore, finite element models were employed to validate the experimental and simplified model results. The findings suggest potential shear failure in shallow socket connections, which can be mitigated by using the combined socketcorrugated pipe method that alters force transmission paths. As the axial load ratio increases, both the ultimate lateral load capacity of the specimen and the local stresses at the column base increase. In addition, the ultimate lateral load capacity of the column and the stress of the connection reinforcement are increased by increasing the strength of the longitudinal reinforcement, consequently amplifying the extent of joint area damage. Finally, a simplified strut-and-tie model of the SCPC, validated against numerical and experimental data, accurately represents force paths, ultimate lateral load capacity and failure modes in socket joints.

Abstract ：
The quantification of uncertainties in civil structures poses a significant challenge due to the need to update a large number of unknown parameters, which can significantly increase the computational workload. A potential solution to this problem is the use of Approximate Bayesian Computation (ABC) approaches, which have gained attention in recent years. However, most existing ABC methods are limited in their ability to handle a large number of unknowns. To address this limitation, this study proposes a decentralized approach for uncertainty quantification in civil structures. In this approach, the structure is divided into several parts, and the uncertainties in each part are estimated independently. The proposed method utilizes the wavelet domain technique to eliminate the interfacial force of the target part and employs a recently developed variational inference approach to quantify the uncertainty in the target substructure. A three-span beam, a 2D truss, and an eight-story building were tested to evaluate the efficiency and feasibility of this approach. The results show that uncertainties in large structures can be estimated and that the proposed method is robust to high levels of measurement noise.

Abstract ：
The ageing effect in the life-cycle assessment should be considered for the high-strength steel structures constructed in corrosive environments and high-seismicity zones. Additionally, the structures can suffer multidimensional seismic excitations because of the spatial effect of ground motions. Therefore, this study aims to investigate the impact of different loading protocols on the mechanical properties of Q690 steel columns with Hsection during the whole life-cycle. Firstly, numerical methods considering time-varying corrosion process are used to simulate the ageing steel columns. After that, the nonlinear hysteretic behaviors of the ageing steel columns under different loading protocols are investigated. The factor of resistance degradation (the degree of degradation of ultimate resistance) is employed to quantify the effect of loading protocols on ageing steel columns. Finally, the biaxial ultimate interaction curve considering the ageing effect and a practical design process are proposed. The findings demonstrate that the steel columns exhibit different mechanical properties under various loading protocols, and the coupling direction of bi-directional displacement loads influences the degree of degradation of ultimate resistance. As service time increases, the factor of resistance degradation of steel columns gradually reduces by up to 40%. The proposed biaxial ultimate interaction curve has acceptable accuracy. These findings emphasize the importance of employing the unfavorable loading protocols in conducting the seismic design of the steel columns in different life-cycle stages.

Abstract ：
As critical lifeline systems, transportation network (TN) and electric power network (EPN) are highly susceptible to natural hazards, such as earthquakes during their service life. At the same time, restoration of damaged TN and EPN is essential to support the post-earthquake reconstruction and emergency rescue in affected areas. Restoration strategies were traditionally developed for TN or EPN separately. However, neglecting the potential interconnection between these two networks in the recovery phase may lead to detrimental consequences, as in real-world scenarios, the obtained strategy may be less efficient or even unfeasible given that recovery of one system is usually dependent on the others for service provision. Accordingly, this paper presents a resilience-based framework for post-earthquake restoration of interdependent transportation-electric power networks. In this framework, restoration independencies and functionality dependencies are introduced to represent the interaction between TN and EPN. Then, a bi-level optimization model with the objective of maximizing seismic resilience is established to characterize the network recovery problem. Furthermore, a solution algorithm that incorporates a genetic algorithm and a chromosome validity test operator is designed to obtain the near-optimal solution. Finally, the proposed framework is illustrated through two numerical examples.
