To effectively prevent the buckling-restrained braced reinforced concrete (BRB-RC) frame substructure from shear or flexural-shear failure caused by frame action prior to the BRB, a controllable failure mode design method based on a novel sliding gusset connection was proposed. The method addresses problems of the current siding gusset connection, such as the limited bearing capacity of the anchorage plate and the unreasonable design of the shear capacity of substructure beams. Quasi-static tests were conducted on five full-scale BRB-RC subassemblages, one with a traditional connection and

This paper conducted an experimental study on seismic performance of weld box-shaped columns made of Q345FR and Q460FR fire-resistant steels to enhance the application of fire-resistant steel structure in seismic regions. Through a validated numerical model, a parametric study was subsequently performed to clarify the influence of axial load ratio, slenderness and plate width-to-thickness ratio on the seismic behavior. The fire-resistant steels demonstrate an obvious cyclic-softening behavior. Columns with cross-section of ‘Level 1’ in GB 50011—2010 exhibit a failure mode

In order to study the lateral overstrength capacity and safety reserve of reinforced concrete (RC) structure, the low-cyclic reversed loading tests of the scaled plane structural specimens were conducted, as well as the pushover analysis of the prototype building structure. Taking seismic structural level as the parameter, the allowable stress method was adopted to design three twelve-storey RC frame structures and three twelve-storey RC frame-shear wall structures. One-bay plane structure at bottom three-stories was selected to conduct the seismic test of twelve (1/4 scaled) specimens, whi

In this paper, an experimental study was conducted involving one earthquake-damaged frame beam and three earthquake-damaged prefabricated frame beams to investigate the seismic performance of earthquake-damaged prefabricated groove connection frame beams reinforced with high ductility concrete (HDC). The beams were subjected to low-cyclic reversed loading tests to analyze the failure modes and seismic performance. The results show that HDC forms a constraint effect to effectively restrain the cracking and damage component. The bearing capacity of the HDC-reinforced earthquake-damaged frame

To investigate the dynamic response and seismic performance of the tower structure in a traditional style building under earthquake motions, a specimen of Xi’an Tianren Chang’an Tower with a scale ratio of 1/15 was designed and fabricated and subjected to simulated seismic shaking table tests. The dynamic characteristics of the specimen, such as natural frequency, damping ratio, and stiffness degradation rule, were obtained through white noise frequency sweeping. The dynamic responses, including acceleration amplitude factor, floor displacement, inter-story drift ratio and shear
