| 摘 要： | 纯框架被分类为典型的韧性、名义韧性和GLD(重力荷载设计)。根据侧向抗力、层间位移的分布和构件屈服的次序,可对这些结构的抗震性能进行评估。在研究中,对一个典型的5层框架按照(a)韧性;(b)名义韧性;(c)GLD;(d)改进的GLD方法进行设计,采用非线性时间序列分析和推覆分析,提出了混凝土框架抗震评估的分析方法。通过有效的试验结果验证了分析模型。采用分析模型评估了5层框架的抗震性能。可推断出,在所考虑的地震荷载下,韧性和名义韧性的框架性能良好,而GLD结构的抗震性能不令人满意。损坏的GLD框架被加固后,抗震性能有所提高。

| Abstract: | Moment resisting frames (MRF) are typically clas-sified asductile,nominally ductile, andGLD(GravityLoad Designed). The seismic performance of these struc- tures can be evaluated in terms of its lateral load resistance, distribution of interstory drift, and the sequence of yielding of the members. In this study a typical 5-story frame is de- signed as (a) ductile, (b) nominally ductile, (c) GLD, and (d) retrofitted GLD. This study presents an analytical ap- proach for seismic assessment of RC frames using no... |
