摘要

在现有研究成果基础上提出一种新的基于能量和位移的耗能减震结构抗震设计方法,该法综合考虑了能量和位移指标,无需将结构进行简化,能准确地计算出耗能器的数量和布置位置,减少了迭代计算过程。采用ABAQUS有限元软件对安装位移相关型耗能器的某14层钢框架结构进行基于重要性能目标的抗震设计,结果表明本文方法能较好地满足预期的性能目标。
Based on current achievements,the new energy and displacement based seismic design method was established for energy dissipated structure in this thesis.Indexes of energy and displacement were considered in this method.According to this method,the structure need not be simplified,and the number of energy devices and locations can be accurately calculated.It overcomes the shortcomings of iterative procedure.Based on the method proposed in the thesis 14-story steel structure with displacement-dependent energy dissipated devices are studied by using the finite element analysis programe ABAQUS.The results indicate that the performance-based seismic design method proposed can generally meet the expected performance objectives and is fessible in the thesis.
