Lateral Stiffness Ratio

There are two typical seismic damage characteristics to the masonry building with frame shear wall structure at first two stories, and the lateral stiffness ratio of the third storey to the second storey is one of the key factors mostly affecting the seismic performance of this kind of building. However, some factors are not considered sufficiently in current Chinese seismic codes. According to the theory of performance-based seismic design, the seismic performance of this kind of structure is analyzed in this paper by taking time-history analysis on models which with different storey stiffness ratios. The results show that when the lateral stiffness ratio controlled in a reasonable range, the upper masonry deformation can be ensured in a range of elastic roughly, and the bottom frame can be guaranteed to have sufficient deformation and energy dissipation capacity. Finally, according to the seismic performance characteristics of masonry building with frame shear wall structure at first two stories, especially the characteristics under strong earthquakes, a method of simplified calculation model for the upper masonry is discussed in this paper.

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.

Damage Characteristic

The paper analyses the damages of the frame structure with bottom weak layer considering of Wenchuan earthquake. The analysis result indicates the current design method "pure frame" is imperfect. The related research shows that important reason for the bottom weak layer’s breakage is the stiffness mutation which is caused by the filler wall. If we arranged partial shear wall structure in the bottom weak layer, the adverse effects of stiffness mutation will be decreased, and improve the seismic performance of the frame structure with bottom weak layer.
