Study on Seismic Performance of Irregular RC Frame with Specially Shaped Columns

摘要

According to the code and technical regulation, a irregular RC frame with specially shaped columns have been designed, which situated at the area of fortification intensity 7. Subsequently, the nonlinear dynamic analysis has been carried out for the structure by inputting ground motions in two directions. After summing up the calculation results, this paper have examined seismic performance of the structure under the rare seismic actions and given a primary evaluation on the structure to see if it achieves the predetermined seismic aims. It indicates that the structure designed the codes can achieve the predetermined seismic aims under the rare earthquake.
