Abstract: | This paper is based on the shaking table test of one small-scale micr-oconcrete eighteen-story building, which was done in the Engineering structure Institution of Tongji University. In this paper, using system identification method , study its dynamic model and elastroplastic dynamic response.The special dynamic response properties and the weak links of earthquakeresistant have been found.And some design suggestions have been Pzestent. |
