MIDAS有限元分析在异形建筑玻璃采光顶结构检测中的应用

The Application of MIDAS Finite Element Analysis in the Detection of Glass Daylighting Roof Structure of Special-shaped Buildings

在既有建筑玻璃采光顶结构检测过程中,对于建筑玻璃采光顶钢结构及异形玻璃面板的承载力复核难以采用规范公式法进行计算。基于此,文章结合某商业综合体异形建筑玻璃采光顶工程实例,运用MIADS有限元软件对整体钢结构网壳和典型玻璃面板进行建模及有限元分析,并对钢结构及玻璃面板的承载能力与相应规范进行复核。结果表明,MIDAS有限元软件在异形建筑玻璃采光顶结构建模与分析方面有较强的适用性,其分析结果可为异形建筑玻璃采光顶的结构检测提供一定依据。

In the detection process of the existing building glass delighting roof structure,it is difficult to calculate the bearing capacity of the steel structure building glass delighting roof and the special-shaped glass panel by the standard formula method.Based on this,combined with a commercial complex special-shaped building glass daylighting roof project example,this paper uses MIADS finite element software to model and analyze the whole steel structure latticed shell and typical glass panel,and rechecks the bearing capacity of steel structure and glass panel with the corresponding specifications.The results show that MIDAS finite element software has strong applicability in the modeling and analysis of the special-shaped building glass delighting roof structure.The analysis results can provide a basis for the structure detection of the special-shaped building glass delighting roof.
