摘要
用SAP2000大型通用软件建立一个空间正放四角锥桁架模型,模型材料分别采用胶合木和钢材,通过比较这两种材料制成的桁架的受力性能的差别,探讨木桁架工程的可行性。同时,由于一般研究都将桁架的节点简化成铰接或者刚接,但这种简化方法与实际情况的吻合程度不够理想,因此,在节点处理上采用半刚性节点模拟实际的连接方式,比较半刚性连接与铰接和刚接的差别,得出一些普遍规律。
A space truss model was established by using a program called SAP2000. The material of the model is glulam or steel. The objective of this research is to determine the feasibility of wood truss by comparing these two models made of different materials. Meanwile, the joint of truss is usually simplified as pinned joint or rigid joint, which is not a reasonable hypothesis, consequently, in this research, semi-rigid joint was used to model the factual joint circumstance. By drawing the comparisons between semi-rigid joint and pinned joint or rigid joint, some useful laws are desired to be obtained.
