仿古建筑结构设计分析

Structural design and analysis of the imitation antique architecture

通过对某仿古建筑结构设计过程进行分析,总结仿古建筑结构设计中的注意事项及解决方案。针对特别不规则的仿古建筑结构抗震专项审查提出的意见,对结构采用两种不同的计算软件进行对比分析,并取两种计算结果进行包络设计,根据分析结果提出以下建议:对错层框架柱应提高其抗震等级;对大悬挑结构应考虑竖向地震力对结构的影响。对缺乏相关试验研究的、刚度突变的节点设计提出了相对可靠的设计方法。

Through analysis of the structural design process of an imitation antique architecture, frequent problems and relevant solutions were summarized. According to structure experts＇ suggestions on the irregular imitation antique architecture in special seismic review, two different structural analysis softwares were used to analyze the structure and results were compared to choose the envelop values to design. According the analysis results, following suggestions are proposed ： the seismic design level of split frame columns should be raised and vertical earthquake should be considered for large cantilever structure. Relatively reliable design methods for stiffness mutational joints are also put forward to make up for the deficiency of joints experimental data.
