Multistory parking structures are a promising exploration avenue to address the acute need for parking spaces, and their floors are often joined with mechanical connectors to form a floor system. The properties of floor‐to‐floor connectors directly affect the seismic behavior of parking structures. Thus, the effectiveness of diaphragm action with several different typical floor‐to‐floor connectors was investigated and the natural frequencies and seismic performances of the parking structures were obtained. The results show that the mechanical characteristics of connectors in precast elements have a crucial influence on the diaphragm effectiveness of large‐span concrete structures with precast double‐tees under strong seismic action.

“…These connections make the wall system have an equivalent behaviour with conventional cast-in-situ concrete structure. During the past decade, the monolithic wall system has been studied using the experimental and analytical methods by a number of researchers [1][2][3][4][5]. These researches have shown that the monolithic wall system have excellent seismic performance, and the structural integrity can be guaranteed.…”

A novel low-rise bolt - assembled precast concrete sandwich wall panel structure for rural residential houses was proposed, in which the connections between wall and wall, and wall and floor were connected by high strength bolts and steel plates. The bolt joints can be easily installed and disassembled. They are replaceable to make the precast structure demountable and reassembled. All the components are connected together by the novel bolted connectors. This paper presents the shake-table tests of a full-scale two-story bolt-assembled precast concrete sandwich wall building. The results indicated that the proposed structural system had good seismic performance and remained in the elastic stage with no damage after 9-degree rare earthquake excitation for the Model-1. The Model-2 exhibited excellent capacity and performed satisfactorily under the excitation up to 0.8 g. Cracks were observed at the wall openings and the base of walls and columns, which was similar to that of a cast-in-situ structure. The damage statuses were mainly light damage and moderate damage. The bolt connection joints were not anti-seismic weak places and had good seismic performance. Equivalent base shear method is suitable for estimating the seismic demand of the proposed precast concrete sandwich wall panel structure.

Summary Reinforced concrete (RC) precast shear walls are commonly used in building structures. For transportation ease, large walls are divided into smaller segments and assembled at the construction site with various connection methods. This study focussed on the RC precast shear wall assembled using steel shear keys, which is simply called the steel shear key wall (SSKW) in this paper. Three SSKW specimens were designed and built by considering different sizes and numbers of shear keys. Quasi‐static cyclic loading tests were performed to investigate the strength and stiffness of the assembled SSKWs and the behaviour of the wall segments and floor slab. We found that adding strength and more shear keys gradually increased the lateral resistance and stiffness of the specimens and decreased the distortion and damage to the floor slabs. However, the specimens also exhibited lower ductility and energy dissipation with increasing link strength. Finally, an appropriate coupling ratio for SSKWs was suggested for their design in practical engineering.
