Shrinkage Effect

In order to discuss the effect of different concrete strength on the seismic behavior of the L-shape steel reinforced concrete (SRC) short-pier shear wall , this article analyze three L-shape steel reinforced concrete short-pier shear walls of different concrete strength with the numerical simulation software ABAQUS, revealing the effects of concrete strength on the walls seismic behavior. The results of the study show that the concrete strength obviously influence the seismic performance. With the concrete strength grade rise, the bearing capacity of the shear wall becomes large, the ductility becomes low, the pinch shrinkage effect of the hysteresis loop becomes more obvious.

A new type of construction employing shaped steels as boundary elements and layered braces of RC(Reinforced Concrete) short-pier shear wall is put forward. The braces are in X shape and are erected in a multi-storied form. They are embedded in the boundary zone and the web of SRC (Steel Reinforced Concrete) short-pier shear wall respectively to make it possible to improve the bearing capacity and ductility of this shear wall and to improve its seismic performance. Three half-scale specimens of the SRC short-pier shear wall are tested under reversed cyclic loading. High design axial load radio of 0.5 is used. The failure processes and modes of the specimens are observed. The law about bearing capacity and displacement ductility of the specimens influenced by the layered braces structures is revealed. The experimental results show that the displacement ductility is closely related to the amount of stories of braces. The specimens with layered braces structures have better ductility and larger bearing capacity, and therefore the layered braces structures effectively improve the seismic performance of the SRC short-pier shear wall.

The structural behavior of a steel reinforced concrete (SRC) transfer beam in high-rise building is studied in the paper. Mechanical properties and deformation characteristics between transfer beam and shear wall are analyzed by an analytic approach and the nonlinear finite element method. The stress analytical solutions for the SRC transfer beam are obtained and agree with finite element calculation data in an actual project. The results show that the beam can be as an eccentric tension member, meanwhile the performance of shear wall must be considered. And it also shows that the shear stress and vertical compressed stress must be considered in end both transfer beam and shear wall and there is interaction between the beam and the shear walls above. The results can be used to describe the behavior of the SRC transfer beam under complicated loads.

Rc Shear Wall

CTSRC structure is a new composite structural system for residential buildings and it consists of walls and floors which are made of the prefabricated steel skeleton and the infill of concrete. Four pieces of CTSRC shear wall specimens and one piece of RC shear wall specimen are tested under low cyclic lateral loads to study the final failure modes and analyze its structural seismic performance. It shows that the CTSRC shear wall structure possess adequate bearing capacity, fine seismic performance and ductility. CTSRC shear walls are better than RC shear walls in the seismic behavior, and it could replace traditional shear walls structure applying to practical engineering. Inserting ring used for connecting profile steel can transfer stress well and it is recognized as a reasonable construction measure.

Seismic Design Code

A large number of reinforced concrete (RC) buildings constructed in the 1970s, whose main structural form is fish-bone shear wall, are still used in Qiansanmen area of Beijing. Due to the economical and technical limitation at the time, both the concrete strength and reinforcement ratio are far from satisfying the requirements given in the current seismic design code for concrete structures. In order to investigate the seismic performances of the wall with the low concrete strength and reinforcement ratio, four RC shear wall specimens were constructed and tested. Quasi-static tests considering large axial compression ratio were carried out, and the stiffness, the strength and the energy dissipation capacity of the RC shear walls are investigated. Test results suggest that the wall with low concrete strength and reinforcement ratio has low strength and poor deformation capacity, indicating the necessity of strengthening.
