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.

Bottom Frame

Bottom frame-shear wall structure is a kind of special structure, due to the inharmonious relationship between the frame and masonry walls in bearing lateral capacity and deformation ability, the difference of vertical stiffness in the bottom frame-shear wall structure is bigger, so the structural seismic performance is poor. A six layer bottom frame-shear wall structure seismic strengthening project is established in order to contrastive analyze two kinds of reinforcement scheme, which are additional RC shear wall and additional buckling constraints. Calculation and analysis results show that through setting buckling constraint support in the bottom layer of reinforced concrete frame and selecting rational mechanical parameters, can increase lateral stiffness, reduce the lateral deformation and realize the effect of multichannel fortification. At the same time, the advantage of easy to implement is belong to bottom frame-shear wall structure.

Based on the experiment of four models of reduced scale high-rise reinforced concrete wall under low-reversed cyclic loading, seismic behavior of reinforced concrete (RC) shear wall with diagonal web reinforcement under different ratio of axial compression is studied, in comparison to ordinary shear wall. The experiment result shows that diagonal bars affect the distribution of cracks and help to resist shear slip at the bottom of the wall. Seismic behavior of high-rise shear wall, which horizontal bars are replaced with the same amount diagonal bars in part can be obviously improved when the ratio of axial compression is high, but when the ratio of axial compression is low, the effect is not obvious.

Mechanics Characteristics

The high-rise concrete residential market has been a gradually urban mainstream in recent years, and frame-shear wall structure is more used for high-rise residential structures now. This kind of structure has the advantage that the combination of frame and shear wall make the space free and flexible, and therefore the whole structure has considerable rigidity. The structure can not only satisfy the needs for people living in comfortable, but also has good dynamic and static load bearing capacity. This paper analyzed the mechanics characteristics of the structure and summarized the two kinds of main failure modes of shear wall and frame structure in earthquake. On this basis, the main principles are put forward to improve the seismic behavior of the shear wall. And further some of specific measures and suggestions which can improve the seismic performance for the frame-shear structure are introduced.
