As the main torque sensor for real-time monitoring work, its development is of great significance to people. People use torque sensors to monitor and control torque in real time, which is critical to ensure the safe operation of the test system. This research is mainly to use the combined sensor method to measure the torsional vibration of the structure and analyze the anti-collapse performance of the shock-absorbing steel frame under strong earthquake. Experimental data shows that the limit bending moment of JD01 without end plate reinforcement is 130.7 kN• m, while the limit bending moment of end plate reinforcement is 160.7 kN• m. Compared with JD01, the bending ability of JD02 has increased by 22.95%. The results of the study show that the configuration of the reinforcing material of the bottom plate can effectively alleviate the stress concentration problem of the bottom plate, limit the surface deformation of the bottom plate, improve the rotation capacity of the node, and improve the support capacity of the node. The buckling restraint support can act as a reverse member of the elastic stage, supporting part of the horizontal shear force. The elastoplastic stage effectively adjusts the reverse side rigidity of the floor, adjusts the shear distribution of the floor, reduces the shear value of each layer, and finally delays the main bearing member to enter the elastic stage.

“…Spoke cable-truss structures are a typical type of tensile structures, which has many advantages like the clear path of load transfer, light mass, considerable spanning ability, rapid construction speed, and so on (Deng et al, 2005; Huang et al, 2019). However, traditional spoke cable-truss structures have the two disadvantages of weak lateral stiffness and weak anti-collapse ability (Xue et al, 2021; Zhao et al, 2010), therefore a new crossed cable-truss structure system is proposed in the paper based on the two disadvantages.…”

To overcome the weak lateral stiffness and weak anti-collapse ability of traditional spoke cable-truss structures, the crossed spoke cable-truss structure (CSCTS) is proposed. As structural stiffness and bearing ability are generated from prestresses produced by tensioning cable length, it is necessary to study the influences of manufacturing errors on CSCTS. The structural design method is proposed by theoretical derivation and the finite element (FE) model with a span of 100 [Formula: see text] is designed for CSCTS. The influences of manufacturing length errors on the mechanical behaviors of CSCTS are studied under four different conditions based on FE model. The influences of manufacturing length errors on the static behaviors of CSCTS are further studied under full-span and half-span loads. Then the control criteria of cable length errors are obtained by theoretical method under the same and different manufacturing length errors. The results show the structural design method can solve the reasonable shape and self-stress mode of CSCTS. The influences of the elongation or shortening of cables and struts on the sensitivity indexes of CSCTS are equal. The internal force variations are the same under different prestress states when length errors are unchanged. Manufacturing errors have greater influences on cable-truss frame itself than others. The influences of manufacturing errors at different positions on internal forces are similar under full-span and half-span loads, which is more sensitive to half-span loads. When construction method of un-adjustable cable length is used, the reasonable control criteria of cable length errors can be adopted considering calculation amount and project costs. The contents can support some meaningful references for the design and construction of CSCTS.

“…Spoke cable-truss structures have many advantages of tensile structures, so many practical projects are built in the world, like Foshan Stadium [11], Shenzhen Baoan Stadium [12], Yueqing Stadium [13], Busan Stadium in South Korea [14]. Meanwhile, there are many static and dynamic experimental studies and numerical studies on spoke cable-truss structures [11,13]. It is found from the existing studies that although the spoke cable-truss structure has many advantages, its progressive collapse ability is weak.…”

Study on Static and Dynamic Experiment of Spatial Cable-Truss Structure Without Inner Ring Cables Based on Grid-Jumped Layout of Struts

Cable-truss tensile structures are one of the most imperative types of spatial structures, and a spatial cable-truss structure without inner ring cables (SCSWIRC) is a new type of cable-truss tensile structure. Although SCSWIRC has a strong anti-collapse capacity, its construction forming is difficult. Based on the concept of grid-jumped layout for struts, the experimental model with a span of 6 m is designed, and then three grid-jumped layout schemes are proposed to simplify structure system. The static and dynamic properties of experimental and finite element models are systematically studied. The results show that experimental values agree with simulation values. The errors of the static experiment are in the range of 6%~11.53% and the errors of the dynamic experiment are in the range of 5%~8%. The grid-jumped layout has negligible effects on the internal forces of cables. However, it has excellent effects on the internal forces of struts and nodal displacements at the grid-jumped layout, so the mechanical property of struts needs to be rechecked after grid-jumped layout. The mechanical property of the optimal grid-jumped layout scheme does not change compared with original scheme. The optimal grid-jumped layout scheme not only simplifies SCSWIRC, but also reduces the amount of steel. The study can promote the application of SCSWIRC in practical engineering.
