Abstract
In former days, the scantiness of stirrup allocation in old buildings is very common. After several vibrations caused by earthquakes, we can know that because the shear strengths of joints of structures are poor, their joints will suffer from shear failure, their beam’s hinges cannot work very well, and even the hinges cannot be formed. Those factors would reduce the seismic capacity of structures.The thesis deals with the difference about shear failure towards the seismic capacity of buildings. We make beam-column joint a single element emulation by the commercial software SAP2000 Nonlinear Version. The way of preference settings will be shown in chapter 3. Followed the description mentioned in Chapter Two and Three, in Chapter Four we will plan a frame for the size of design sections and make a pushover analysis, and then explain the result. Finally, we will make a conclusion in chapter 5. According to the result, we can find that the influence of the poor strength of beam-column joint is very conspicuous. If there is no enough hoop quantity allocation or no good ductility of structures, the seismic capacities of buildings will become very poor. Eccentric is also an important factor towards the seismic capacities of buildings. When the discrepancy between widths of beams and ones of columns is not big, eccentric will not be the main factor.
