均布荷载作用下不同形式连体结构裂缝分析

为了研究不同形式连体结构在竖向均布荷载作用下的裂缝开展情况,采用ANSYS有限元软件建立3种不同结构形式的连廊局部模型,在模型顶部施加竖向均布荷载,首先进行结构内力分析,然后在结构顶部施加p=0.7MPa均布荷载进行非线性弹塑性分析,研究裂缝的发展过程,通过对比分析,得出模型3的连廊结构形式为三者中最佳,最后对实际工程结构设计提出一些建议.

Analysis of Crack Development of Connective Structures under Vertical Uniform Load

Aimed at the research on crack development of connective structures under vertical uniform load,the finite element software ANSYS was adopted to establish three forms of local models of the connective structure with vertical uniform load exerted on the top of the models, The internal force of the structure was analyzed, and with the uniform load of 0.7 Mpa exerted on the top of structure, the nonlinear analysis was performed to study the development of cracks. The results of comparative analysis show the third model is the best of the three forms of connecting structures. Finally,some suggestions are given for the design of practical engineering structures.
