摘要 ：
Cable -net structural design generally includes the initial state, load state, and zero -stress state, and adjusting design variables through manual intervention is difficult to correlate these different states. Thus, correlating the structural configurations among these states and finding the corresponding design variables is a challenge. By clarifying the relationship between the three states, a complete automated design process with three states connected by two new parameters is presented. Two typical cable nets are designed and validated, and the corresponding indicators are evaluated and recommended. This method can be applied to almost all flexible cable nets with constrained boundaries and provides an efficient way for designers to obtain reasonable results in the preliminary design stage. The proposed method expands the entire design path from initial form -finding to the load state and the zero -stress state, providing an important reference for the standardized paradigm and automated approach to flexible structural design.

摘要 ：
Cable-truss structure is a typical form of cable-strut tensile structures, which consists of upper cable system, lower cable system and several vertical struts. As with the general cable-strut tensile structure, only when the reasonable geometric shape matches the feasible prestress distribution can the cable-truss structure obtain structural stiffness and bear the external load. Once the geometric shape is unreasonable, the cable-truss structure is just a mechanism without bearing capacity and cannot be stiffened by introducing prestress. Consequently, a reasonable geometry is the premise for cable-truss structure to become an effective load bearing system. In this paper, an equivalent equilibrium force model, called EEFM, is proposed according to the geometric-mechanical characteristics of cable-truss structures. A cable-truss structure in this model is split into upper and lower cable systems with equivalent nodal forces. The geometric rationality can be easily evaluated from the equivalent nodal force relationship. According to the geometric topology and equilibrium equation of two cable systems, the self-stress mode of the structure with reasonable geometry can be directly obtained. For structures with unreasonable geometry, the node coordinates of one cable system are corrected based on the other cable system. Several cases are presented to verify the accuracy and validity of the proposed method. This method can be used for shape design, geometric correction and force finding, and has greater advantages for cable-truss structures with asymmetric or complex space configuration.

摘要 ：
Carbon fibre-reinforced polymer (CFRP) straps can be utilised as tension members in structures on account of their high-strength properties. The development of an effective anchorage device for CFRP straps that can fully utilise the strength of straps before anchorage failure is an ongoing technical challenge. To address such knowledge gap, a novel anchorage device termed windingwedge anchorage that combines winding and wedge anchorage mechanisms is reported herein. For the winding anchorage component, different numbers of winding turns are applied. For the wedge anchorage component, three different types of wedge anchorage systems are investigated namely bonding, friction clamping, and friction non-clamping. Initially, the working mechanism, theoretical winding-wedge anchorage model (herein theoretical model), and design parameters are determined. Experimental and finite element analyses are then reported to assess the behaviour of the anchorage including failure modes and anchorage efficiencies. The accuracy of the theoretical model is also reported. It is concluded that the efficiency of the anchorage device is primarily dependent on the wedge anchorage component. Moreover, the bonding wedge anchorage component performed better than the other two wedge anchorage systems. The theoretical model and experimental results revealed that 1.5 winding turns results in an optimal interaction between the winding and wedge anchorages components.

摘要 ：
Purpose In order to optimize SCSWIRC, the simplification and further optimization method is proposed. SCSWIRC's optimization includes two levels. The first level refers to simplifying structural system from the perspective of components; the second level refers to optimizing components' sectional areas from the perspective of mechanics. The first level aims to remove redundant components, and the second level aims to reduce structural self-weight based on the first level. The purpose of the paper is to simplify SCSWIRC's structural system and optimize structural self-weight and reduce construction forming difficulty. Design/methodology/approach Grid-jumping layout and multi-objective optimization method is used to simplify and further optimize Spatial cable-truss structure without inner ring cables (SCSWIRC). Grid-jumping layout is used to simplify remove redundant components, and multi-objective optimization method is used to reduce structural self-weight. The detailed solving process is given based on grid-jumping layout and multi-objective optimization method. Findings Take SCSWIRC with a span of 100m as an example to verify the feasibility and correctness of the simplification and further optimization method. The optimization results show that 12 redundant components are removed and the self-weight reduces by 3.128t from original scheme to grid-jumping layout scheme 1. The self-weight reduces from 36.007t to 28.231t and feasible coefficient decreases from 1.0 to 0.627 from grid-jumping layout scheme 1 to multi-objective optimization scheme. The simplification and further optimization can not only remove the redundant components and simplify structural system to reduce construction forming difficulty, but also optimize structural self-weight under considering structural stiffness to reduce project costs. Originality/value The proposed method firstly simplifies SCSWIRC and then optimizes the simplified SCSWIRC, which can solve the optimization problem from the perspective of components and mechanics. Meanwhile, the optimal section solving method can be used to obtain circular steel tube size with the optimal stiffness of the same areas. The proposed method successfully solves the problem of construction forming and project cost, which promotes the application of SCSWIRC in practical engineering.

摘要 ：
Traditional form-finding methods usually assume that the boundary conditions of cable roofs are fixed constraints without considering the influence of the supporting frame. However, the cable roof interacts with the supporting frame and they work together as a whole. Pre-tensioning for cables will cause the deformation of the supporting frame toward the center, which will lead to the deviation between the actual initial equilibrium state and the target design result, especially the interconnection between the cable roof and the flexible supporting frame. To solve this problem, the interaction mechanism between the cable roof and supporting frame was first analyzed theoretically in this study. A novel form finding method of cable roof structures integral with supporting frames was proposed. The parameters that affect the form-finding result were analyzed, including the prestress, the stiffness of the supporting frame, and the stiffness of the cable. For the convenience of engineering applications, this method was developed using the ABAQUS software and was compiled in the Python language. According to different types of cable roofs, two form-finding schemes and two algorithmic procedures were proposed. The form -finding results of six typical cases were presented. The novel method was confirmed to be feasible and may be valuable for engineering applications.

摘要 ：
The cable net forming the minimum surface is a kind of equal tension cable net, and any cable force value selected will not change the configuration of the minimum surface. The cable force can be directly set as the constant value to solve the minimum surface. The cable length can be taken as the only iterative solution parameter to establish the equilibrium equations of free nodes, solve the coordinates of free nodes, and obtain the minimum surface configuration. Base on this theory, a form finding method for the minimum surface of cable net, namely the cable length iteration method, is proposed in this paper, and the corresponding analysis steps and algorithm flow are presented. Some typical cases with different boundary conditions and topology forms were used to compare the novel method with the traditional force density method. The effectiveness of the method is proved, and its convergence speed and calculation accuracy are the same as that of the force density method. For the configuration of the cable net with analytical expression, an improved method for the cable length iteration method is proposed, and the results show that the improved cable length iteration method can solve the minimum surface configuration faster and the convergence speed can be doubled.
