摘要
某体育馆是由网架结构和落地提篮形桁架组成的杂交结构,圆管相交采用T形相贯刚接节点。介绍了工程结构的设计、分析过程。利用半经验半理论公式,介绍了圆管结构T形相贯刚接节点的计算方法和节点柔性对整个结构体系分析的影响。分析结果表明,在一定几何条件下,T形相贯节点可以看作刚接节点,但应考虑一定的节点柔性对整体结构变形的影响。
A gymnasium consists of space truss structure and shopping basket shaped truss structure, and the T-type rigid connection joint is adopted when the circular tube is intersected. The structural design and analysis are introduced. Based on the semi-experience and semi-theory formula, the calculation methods of the T-type rigid connection joints in circular tube structure and the effects of joint flexibility on the structure system are presented. The results show that the T-type connection joint can be regarded as rigid under some circumstances but the effects of certain joint flexibility on the structure system should be taken into account.
