摘要
以某学校体育馆项目为例,综合比选预应力混凝土梁和平面单向钢桁架楼盖方案。本项目采用平面单向钢桁架楼盖,桁架选型及杆件截面设计采用盈建科软件进行整体建模分析,满足承载力和正常使用要求。同时,二层篮球训练馆考虑其组织体育活动功能要求,补充楼盖舒适度计算。最后,为保证“强节点,弱构件”设计概念,选取桁架杆件与型钢柱连接典型节点,进行节点有限元分析。本文的分析为类似包含平面单向钢桁架楼盖的学校体育馆项目的设计提供参考。
This passage discusses the comprehensive selection between prestressed concrete beams and flat unidirectional steel truss roof systems for a school gymnasium project.The chosen solution involves a flat unidirectional steel truss roof,with truss selection and member section design modeled and analyzed using YJK software to meet load-bearing and usability requirements.Additionally,the second-floor basketball training facility considers comfort calculations based on its sports activity requirements.To ensure the"strong nodes,weak members"design concept,typical nodes connecting truss members and steel columns are subjected to finite element analysis.The analysis in this paper serves as a reference for the design of similar school gymnasium projects featuring flat unidirectional steel truss roofs.
