侧向荷载分布在竖向不规则结构中的仿真分析

Application of Lateral Load Patterns in the Simulation Analysis of Vertical Irregular Structures

侧向荷载分布形式是静力弹塑性分析方法的基础,影响到结构分析的准确性和评估结果的可靠性。基于常用和改进的侧向力模式对竖向不规则结构进行分析,力求得到合适的侧向力分布形式。基于结构计算软件,采用多种侧向力分布形式,针对四个竖向不规则结构进行仿真分析,得到了结构的楼层位移和层间位移等指标,并与时程分析结果进行对比。结果表明应采用多种侧向力分布模式对竖向不规则结构进行计算,从而为科学研究的进行和工程实际应用提供参考。

The lateral load patterns are the basis of the pushover analysis which impact the accuracy and reliability of assessment. In this paper, the common and improved lateral load patterns is used to analyze the vertical irregular structure to find the suitable pattern of lateral load. The software is used to analyze the vertical irregular structures suffered different patterns of lateral load. The floor displacements of the story drifts obtained by the pushover analysis were compared with the results of time - history analysis. The results illustrate that various lateral load patterns should be used to analyze the vertical irregular structure. The research of this paper provides reference for the scientific research and the applications of practical project.
