轻型复合结构抗震性能分析(Ⅱ)——结构的滞回曲线、位移反应、基底剪力反应规律
|
摘要
作为轻型复合结构抗震性能分析的第Ⅱ部分.对该结构1/2模型进行了拟动力和拟静力试验研究,并对该模型进行了空间有限元弹塑性地震反应分析.对结构模型的滞回曲线、位移反应、基底剪力反应规律的试验结果进行了分析比较.理论分析与试验结果吻合较好,空间有限元弹塑性地震反应分析可用于该结构的抗震设计;由于结构刚度较大,周期较小,随着裂缝的出现和开展,结构的刚度会逐渐减小,周期会逐渐加大,渐渐接近场地土的卓越周期而产生共振现象,因此,对刚度较大的结构抗震设计时,避开场地土的卓越周期非常必要.
As the partⅡof analysis on seismic behavior of light composite structure,it is intended to direct seismic design of the structure,A model of light composite structure with ratio 1:2 is studied through the pseudo-dynamic and pseudo-static test and elasto-plastic earthquake response analysis with 3D finite element method with commercial software MARC.Test results of law of hysteresis loop,displacement response and base shear response of the model are analyzed and the analyzing results are compared with results of elasto- plastic earthquake response analysis.The analyzing and comparisons show that the analyzing results coincide with test results fairly,and elasto-plastic earthquake response analysis with finite element method can be used in seismic design of the structure.Because of the large rigidity and the short period of the structure,with the appearance and development of the crack,the rigidity of the structure will be gradually redaced,and the period of the structure will be gradually increased and close to predominant period of the site,and the resonance occurs.So when the large rigidity structure is designed,how to avoid the predominant period of the site is necessary.
