Abstract ：
颗粒阻尼技术因减振效果好、作用频带宽等优点使其在土木工程领域中具有良好的应用前景,然而因其具有高度复杂的非线性力学特性,并缺少合理的力学模型,限制了其在实际工程中的应用和发展。鉴于此,以土木工程应用为背景,在不考虑阻尼颗粒发生堆积的前提下,通过引入惯容器来考虑颗粒群滚动对阻尼器减振机理及减振效果影响,建立了考虑惯容的多颗粒阻尼器等效单颗粒力学模型;结合颗粒运动状态,分别进行了未碰撞时及碰撞发生后多颗粒阻尼器单自由度结构的响应分析,重点探讨了惯容系数对未碰撞时动力放大系数频响曲线及碰撞发生后周期2次碰撞稳态解析解的影响规律,并采用数值仿真和试验方法进行验证。结果表明,考虑惯容属性后等效模型能够进...

Abstract ：
滚动碰撞式调制质量阻尼器(PTRMD)由调谐质量阻尼器及颗粒阻尼器发展而来,其在土木工程减振控制领域中的研究仍处于初步分析与探索阶段,阻尼器自身参数及外部激励条件对其减振性能的影响尚不明确。在考虑颗粒与主体结构碰撞和摩擦效应的基础上,建立PTRMD力学模型,并将颗粒和结构的振动过程划分为非碰撞过程、碰撞过程及黏滞振动过程;建立PTRMD-单自由度结构运动微分方程并分别对其进行求解;基于数值仿真分析方法,分别对碰撞间隙比、颗粒运动频率比、滚动摩擦因数、碰撞恢复系数、颗粒质量与简谐激励强度及频率等参数对PTRMD减振性能的影响进行研究。结果表明:颗粒运动频率比较小时,PTRMD减振效果随碰撞间隙比...

Abstract ：
在现有多颗粒阻尼器(M-PD)等效单颗粒力学模型研究基础上,通过引入惯容考虑颗粒群滚动对M-PD减振效果的影响,建立了考虑惯容的等效惯性单颗粒模型(EISM),并基于Runge-Kutta算法建立了简谐激励及地震激励下M-PD单自由度结构运动状态的完整求解算法.设计进行了M-PD控制下的单层钢框架振动台试验,探究了不同颗粒填充率对结构顶层位移频响曲线的影响,提出了非堆积状态下EISM参数取值原则,进而进行了EISM模型的试验验证及基于既有等效单颗粒模型的数值对比分析;在模型验证的基础上,基于EISM进行了自由振动、简谐激励及地震作用下减振效果分析及能量变化规律分析.模型验证及减振效果分析结果表明:相比较于现有等效单颗粒力学模型,EISM模型能够进一步反映M-PD减振效果及减振机理,且提出的模型参数取值原则更加适应于非堆积状态下的M-PD数值模拟;不同激励情况下M-PD均具有较好的减振效果,但在最优碰撞间距取值下现有等效单颗粒模型可能会高估M-PD减振效果.

Abstract ：
The vibration of cross laminated timber (CLT) floor is closely related to human-induced loadings. However, research and prediction approaches regarding human-induced vibration of the CLT floor have been mostly limited to a single-person excitation condition. This paper presents new prediction approaches to the vibration response of the CLT floor under multi-person loadings. The effect of multi-person loadings on the vibration performance of a CLT floor was investigated through numerical modelling, experimental testing and analytical investigation. A finite element model was developed through a computational software to perform an accurate analysis of human-induced loadings. An analytical model was established to predict human-induced vibration of the CLT floor under multi-person loadings. Experimental tests were conducted to validate the numerical modelling. Results of both numerical modelling and experimental testing showed that the vibration performance of the CLT floor under multi-person loadings was almost double that under single-person loadings. Thus, multi person activities are more likely to cause the occupants feelings of discomfort. A method for predicting the human-induced vibration of the CLT floor under multi-person loadings was then developed. The measured response, numerical modelled response, and predicted response were compared using an existing design metric, vibration dose value (VDV). The results were largely consistent. It is therefore concluded that the proposed prediction method will enable engineers to design timber floor systems that consider multi-person loadings.

Abstract ：
Self-pierce riveting (SPR) with high connection efficiency and automatic level is suitable for joining galvanized steel sheets in cold-formed steel structures. 51 SPR joints in galvanized steel sheet were tested to study their shear performance. The effects of sheet thickness, sheet thickness ratio, and rivet length on the failure mechanism and shear performance were investigated. And an empirical equation about the relationship of sheet thickness and rivet length was developed. This paper also analyzed the applicability for the existing calculation method of shear strength of SPR joints and the design methods of shear strength of self-drilling screw joints in some specifications, and then proposed a new calculation method of shear strength. The results showed that sheet thickness and thickness ratios were two critical factors in the shear performance and failure mechanism of SPR joints. There was an optimal rivet length for each sheet thickness, which could be calculated directly by the developed empirical equation. Compared with the existing methods, the calculation method of shear strength for galvanized steel sheet SPR joints proposed in this paper considered overall failure modes, and had superior calculation accuracy and favorable stability.

Abstract ：
The installation of energy dissipation devices on building structures can significantly reduce seismic damage. A brief review of first, second and third generation performance-based seismic design (PBSD) theories, and a comparative analysis of existing PBSD methods for energy-dissipated structure systems confirms that design methods based on force, displacement, and energy are inadequate. A more comprehensive approach is the damage-based design method, which can evaluate the seismic performance of structures. However, due to the lack of an analytical relationship between the additional equivalent damping ratio (AEDR) of dampers and the damage degree of the main structure, the current performance design method can only predict the expected damage via an iterative adjustment analysis of damper's design parameters. The authors addressed this problem by analyzing the damage mechanism of the energy-dissipated structure system's core area from the perspective of energy dissipation. It is established an analytical relationship between the AEDR and the damage index of the main structure with dampers via a damage model based on the energy difference ratio and the time-varying AEDR calculation of dampers subjected to ground motions. With this new approach to seismic vulnerability analysis, the performance design flow of the seismic structure system is based on damage control. A case study verifies the accuracy of the damage-degree based AEDR calculation. The proposed damage-based method effectively controls the damage degree of the main structure to the expected damage target. This method is compatible with the displacement-based design method, and which also enriches the research contents of structural seismic design and damage analysis in the third generation PBSD.

Abstract ：
This study developed a special energy dissipation X-bracing for cold-formed steel (CFS) shear walls to improve the ductility of the corrugated steel sheathing. In previous research, CFS shear walls with corrugated sheathing demonstrated poor ductility under cyclic loading. The paper presents a potential solution by adding a special energy dissipation bracing (EDB) to improve the ductility of the corrugated sheet-sheathed shear walls. The EDB can be tuned according to the CFS shear wall base performance to achieve the highest postpeak deflection capacity, thereby significantly improving the seismic ductility. To prove the concept and analyze the feasibility of the new EDB, a test program of nine full-scale shear walls was conducted. The experimental results showed that with the tuned EDB, the corrugated steel sheet-sheathed shear walls had improved ductility with no considerable reduction in the initial stiffness and shear strength. Installing the proposed EDB can be an efficient approach to enhance the seismic performance of CFS-framed shear walls. Details of the test program and discussion are presented.
