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.

Through the ANSYS finite element method, the seismic performance of frame columns reinforced with wing walls has been analyzed, indicating that the wing wall reinforcement can effectively improve the lateral stiffness and remarkably increase the bearing capacity of columns. With the wing wall reinforcement, the envelop area of the column’s hysteresis curve increases, and the bearing capacity improves, however, the shrinking phenomena of the curve suggests that the ductility of the section reduces. When the centerline of the additional wing wall coincides with that of the original column, the hysteresis curve inclines to be full, thus advising overlapping the centerline of the wing wall with that of the original column.
