Based on the flexural-shear and press-flexural-shear test of four scale HSW model building with High Shear-Span Ratio, The seismic behavior of the slit and integral HSW are discussed, then the failure characteristics and capacity of HSW under Vertical load and seams are analyzed. The result of experimental study proves that the ductility and the property of energy dissipation of HSW are well; Vertical load could increase the capacity and deformation, decrease the energy dissipation of HSW. And the seams of wall could improve the ductility and the property of energy dissipation of HSW , lower the capacity.

With the pseudo-static test of 4 concrete-filled square steel tubular column and steel beam joint with outer stiffened ring, this paper discusses the failure characteristics, failure mechanism and seismic behavior of joints under different axial compression ratio. The analysis of the testing results shows: when reached the ultimate strength, the strength degradation and stiffness degradation of joints are slowly and the ductility is also good, the energy dissipation capacity of joints is much better.

This paper deals with an experimental study on the seismic performance of haunched transfer beam structures with varied ratio of section height to thickness of short-leg shearwall (RHT). Based on the seismic tests of three 1:3-scaled specimens under low-frequency cyclic lateral load with constant vertical actions, the failure pattern, the hysteresis curves, the skeleton curves, the energy dissipation capacity, and the stiffness degradation laws of haunched transfer beam structures are investigated. The effects of different RHT (i.e., 5, 6 and 7) on the seismic performance of haunched transfer beam structures are emphasized and analyzed in detail. It is concluded that the rigidity of the structure is noticeable enhanced, the endogen force becomes more evenly distributed and the bearing is more rational with an increase of the RHT; the rationally designed haunched transfer beam structure has a good seismic behavior.

Joints are the forces cross points of members, and the bearing modes are more complex than other members, especially under earthquake action, so the rationality of joints are directly related to the safe reliability of structure. By the pseudo-static test of 4 concrete-filled square steel tubular column and steel beam joint with outer stiffened ring, this paper discusses the failure characteristics, failure mechanism and seismic behavior of joints under different axial compression ratio. The analysis of the testing results shows: the energy dissipation capacity of joints is much better, the degradation of strength and stiffness are slowly when reached the ultimate strength, and the ductility is also good.

Strength And Stiffness

A new type joint of Circular Tubed Steel-Reinforced Concrete (CTSRC) columns was designed in this paper. The structural characteristics, manufacturing process, and mechanical properties of raw materials of the new joint were introduced. In order to simulate the earthquake action, two joint specimens were subjected to low-cycle cyclic loading at the end of the column. Based on the in-depth study of the failure characteristics, load-displacement hysteretic curve, skeleton curve, ductility index, load-strain hysteretic curve in the core area of the joint, energy dissipation performance, strength and stiffness degradation performance, and shear deformation in the core area of the joint during the whole loading process, the seismic behavior of this new type of joint was investigated. The results show that the new joint has reasonable failure characteristics, high bearing capacity, good ductility, excellent seismic energy dissipation performance, and strong resistance to strength and stiffness degradation, which meets the seismic design principle of “strong joint and weak component” and is suitable for the results with special requirements for seismic performance. In addition, preliminary design recommendations were put forward. The research results of this paper can provide a theoretical basis for the application of this kind of new structure.
