摘要:
以框架-剪力墙结构为研究对象,按照我国现行抗震设计规范,设计了一个代表性办公楼结构,建立其非线性分析模型;并选择7个参数用以考虑结构参数的不确定性,选择PGA/PGV以考虑地震动参数的不确定性;结合地震动和结构不确定性参数,采用拉丁超立方采样与正交设计结合的方法,抽样形成地震-结构样本对;利用Perform-3D有限元分析软件,采用增量动力法(IDA)进行结构地震易损性分析,得到了该结构的地震易损性分析结果。研究表明:该类结构能够很好地满足"小震不坏、中震可修、大震不倒"的抗震要求,具有良好的抗震性能。研究成果弥补了目前框架-剪力墙结构地震易损性分析中未考虑结构参数不确定性的不足,可为预测高层框架-剪力墙结构等重大工程结构的地震破坏和损失提供有力的科学依据。
Abstract:
Taking on the frame-shear wall structure as the research object, the structure of a typical office building is designed according to the current seismic design code. The structure of the nonlinear analysis model is established, and the seven uncertainty parameters of structure are selected. The parameter PGA/PGV is selected for considering the uncertainty of ground motion. In combination with the ground motion and structural parameters, the Latin hypercube sampling combined with orthogonal design method is used, in order to take the sampling form for earthquake structure sample. And then the incremental dynamic analysis method is used to take the seismic fragility analysis to consider the parameter uncertainty. And on this basis, the typical structure of the seismic fragility is analyzed, which is shown that:"no damage in Minor Earthquakes, mendable in Moderate Earthquakes, no collapsing in Major Earthquakes" in the seismic requirements, which means it has a good seismic performance. The research results make up for the lack of structural parameter uncertainties in the seismic fragility analysis of frame shear wall structures. It can also provide a strong scientific basis for predicting earthquake damage and loss of major engineering structures such as high-rise frame shear wall structures.
