Review of Seismic Research and Application of Concrete Core Walls in High-Rise Buildings

Abstract eng:
Concrete core walls are widely used to be the main lateral force resisting units of hybrid structure in high-rise buildings in China due to its larger lateral space stiffness and lateral force resistance. But the seismic behavior of this structural system is still under dispute in the field of engineering especially abroad because of few researches on its performance. Therefore, the research for the mechanic behavior and failure characteristic of this structural system has a significant influence on the engineering design. At first, this paper reviewed the application and development of concrete core walls in high-rise buildings home and abroad, based on the analysis of the mechanic behavior, it is pointed that the earthquake resistant performance of the frame-concrete core walls hybrid structure depends on the concrete core walls from the point view of the whole structural system. Then, it is summarized that the experimental studies and the theoretical analysis models adopted in the research of the seismic performance of concrete core walls are far from sufficient for the extensive use of this kind of structural system in high-rise buildings in China. At last, the existing main problems now and the further research for the future on the seismic behavior of concrete core walls are discussed in particular.
