【摘要】 通过建立三维有限元模型,采用ANSYS10.0软件进行静力分析,分别对不开洞填充墙和开洞填充墙中相关系数分析发现,随着墙体宽高比的增加,模型的相对刚度也在逐渐增长,但增长速度逐渐减慢,当填充墙宽高比大于1.5时,宽高比的增大对框架抗侧刚度的增大影响不大,当填充墙宽高比大于1.8时,可忽略墙体宽高比增大对框架抗侧刚度的影响.研究发现,梁柱惯性矩之比对于模型的相对刚度影响很大,框架结构的相对刚度随梁柱惯性矩之比(I2/I1)的增加而减小.更多还原

【Abstract】 Statical analysis of infilled frame structure was conducted based on 3D finite element models by means of software ANSYS10.0.Analyses on relevant parameters of infilled frame walls with or without openings have been carried out seperately,and it is found that the relevant stiffness of the model gradually increases with the ratio of the wall’s width to its height.However,the effect of the width to height ratio of the wall on its structural lateral stiffness becomes much smaller when the value of the width to height ratio is larger than 1.5.The effect can be basically ignored when the width to height ratio is larger than 1.8.It is investigated that the ratio of posts inertia moment to beams has great influence on model’s relevant stiffness.The relevant stiffness of frame structure decreases with the growth of the ratio of posts inertia moment to beams(I2/I1).更多还原
