某博物馆结构设计

Structural design of a museum

某博物馆为钢框架体系,由多组不同跨度和高度的钢拱结构组合而成。设计使用年限为100年,且属于特别不规则结构,需进行性能化设计,分析过程中采用YJK和MIDASGEN两种软件进行了对比。根据分析结果对薄弱环节及关键构件采取了相应的加强措施,保证结构安全。

A museum is a steel frame system composed of multiple sets of steel arch structures with different spans and heights.The design service life is 100 years,and it belongs to a particularly irregular structure.Performance-based design is required.During the analysis,two softwares,YJK and MIDAS GEN,were used for comparison.Based on the analysis results,corresponding strengthening measures have been taken for weak links and key components to ensure structural safety.
