Abstract

In order to compare the difference of seismic response of RC frame structure under single and bidirectional strong ground motions, a 3-story RC frame structure is designed according to the Chinese seismic design code, and the structural seismic response is analyzed under the excitation of 4 sets of bidirectional strong ground motions by using OpenSEES. Then the seismic response parameters are analyzed and compared between the excitation of single and bidirectional strong ground motions. The result shows that the structural inter-story drift ratio under bidirectional strong ground motion is larger than that of excitation of the single component of strong motion and the column concrete compressive strain and rebar tensile strain increase, while the beam concrete compressive strain and rebar tensile strain decrease. The plastic hinge of RC frame is more likely to be formed at the end of column, and the amount of plastic hinge at column ends increases, but decreases at beam ends respectively, compared with excitation of single component of strong motion. Moreover, it is found that different bidirectional seismic input modes have large influence on the inter-story drift ratio and fiber strain, while have small influence on axial compression ratio and failure mode of beam-column joints. The result provides some reference for the seismic design of RC frame considering the effect of the bidirectional seismic action.
