摘要

大型结构中关键构件的力学性能对整体结构的安全性影响重大

但其受力状态复杂

目前的试验条件尚难准确模拟复杂构件的边界条件。鉴于整体有限元模型可以近似模拟结构中构件真实的受力状态

利用单元耦合技术

提出了整体结构中关键构件的模拟计算方法

对某大空间竖向混合结构中的关键构件进行了精细模拟

通过整体计算分析了该结构中Y型混合柱、屋盖下弦节点在复杂受力状态下的力学行为

并以模型试验结果和一般数值计算方法验证了该方法的准确性。提出的方法可为复杂构件力学性能的研究提供参考。

Abstract

Some key members of a large structure have great impact on the structural behavior.However it always is in a complicated loading state

so the experimental technique cannot realize this loading state now.For the structural finite element model could supple approximately the true loading states of the members

a new simulation technique for the complex member is proposed in this paper on the basis of the element coupling technique.In this paper

some key members in a large structure are simulated in micro-scale.Through the structure global computation

the mechanical behavior of Y-type hybrid column and lower chord joint are analyzed.The validity of this method is verified by the comparison with the test and a general finite element model.It shows the proposed method could be used for the mechanical behavior analysis of complex members.
