“…A fracture energy–based constitutive model was developed for the analysis of RC structures under cyclic loading (He et al, 2008). In order to investigate steel- and concrete-filled tubular structures, a series of works on instability, fatigue strength, and hysteretic behaviors were conducted by employing cyclic and biaxial loading tests (Oyawa et al, 2001, 2004a, 2004b; Sugiura et al, 1987, 1991, 1992; Watanabe et al, 1991, 1998; Xu and Sugiura, 2014). In their works, it was found that the axial compressive force had effects on the strength and ductility.…”

Steel-reinforced concrete T-shaped column-beam structure system has superiorities of both steel-reinforced structure and special-shaped column structure. This research focuses on steel-reinforced concrete T-shaped column-beam joint design and experimentally investigates seismic behaviors of the proposed joints. Pseudo-static tests are carried out on three steel-reinforced concrete T-shaped column-reinforced concrete beam joints and one reinforced concrete T-shaped column-reinforced concrete beam joint. The experiments were conducted under bidirectional low-cyclic reversed loading to simulate realistic loading conditions under earthquake. Hysteresis loops of all the specimens, including load–deflection, moment–rotation, and load–shear deformation loops, are plotted for the evaluation of seismic reaction. The working index, ductility coefficient, and equivalent viscous-damping coefficient are calculated for comparisons. Meanwhile, the ductility, capacity of energy dissipation, stiffness degradation, and the function of steel reinforcement in resisting shear force in the joint core area are intensively studied. Based on experimental results, this research analyzes shear-resistant capacity and the inner force transmission in these joints. It is found that the steel-reinforced concrete T-shaped column-reinforced concrete beam joint performs well under seismic conditions; moreover, shear-resistant capacity, ductility, and reliability are satisfactory. Conclusions derived from this research are useful for engineering practice.

Steel reinforced concrete special-shaped column is a new structural form. It has all priorities of steel reinforced structure and special-shaped column structure. Bearing capacity and ductility of this new structure are very good. It also has very excellent applicable quality and pleasing to the eye. But there are still few experimental and research results relevant to this new structure. The design of steel reinforced concrete special-shaped column joints is a most important problem that must be solved to ensure that this new structural could be widely used in the future. This research focuses the attention on the seismic behavior of this kind of joints, and adopts the new joint design style. The pseudo-static test is carried out on joint specimens. Hysteresis loop of all the specimens have been drawn. The energy dissipating capacities are evaluated. Based on the results of experimental research, the behavior of high resistant capacity, excellent ductility and reliability of the joint design method have been manifested. Taking into account all these facts, this article also put forward practical design suggestions on this structure.

“…ey also pointed out that the appropriate design of steel truss will result in the enhancement of structural bearing capacities and the ductility; however, simply increasing the size of chord or webs may cause uncoordinated force distribution in structures. A series of works has been reported by employing cyclic and biaxial loading tests, in which the instability, fatigue strength, and hysteretic behaviors were investigated [51][52][53][54][55]. Condition assessment and energy dissipation of steel shear walls with tapered links under various loadings were investigated using a baseline incremental two-cycle loading protocol [56].…”

Based on existing experimental results, the finite element analyses were carried out on shear wall structures with steel truss coupling beams. is work studied the seismic behaviors and the working mechanism of the steel truss coupling beam at the ultimate state and put forward two parameters: the area ratio of web member to chord and the stiffness ratio of coupling beam to shear wall. e seismic optimum design method of the coupling beam was also proposed. Afterwards, a comparative analysis was implemented on the three-dimensional shear wall model with steel truss coupling beams designed by the proposed design method.e results show that the structures designed by the proposed method have excellent seismic behaviors, the steel truss coupling beams have enough stiffness to connect shear walls effectively, and its web members have appropriate cross sections to dissipate seismic energy.
