内嵌墙板钢框架等效单斜撑简化模型
|
摘要
为了解决已有等效斜撑模型有效宽度计算公式不适用于轻质围护墙板钢框架结构的问题,通过参数分析方法,重新拟合得到适用于内嵌围护墙板钢框架结构的等效斜撑模型有效宽度计算公式,利用已有实验数据证明公式有效性,并考虑影响内嵌围护墙板钢框架结构抗侧刚度的部分关键参数对公式适用性的影响.结果表明:拟合得到的公式在不同跨高比、轴压比、墙板厚度、墙板开洞等情况下均适用;在不同墙板宽度情况下,可通过乘以板宽影响系数KB来调节板宽对计算公式的影响.
To solve the problem that the existing effective width formula of the equivalent strut mode does not apply to steel frame structure with light enclosure wall panels,in this paper,re-fitting the effective width formula of the equivalent strut model for steel frame structure with light enclosure wall panels is obtained by parameter analysis method.Considering the key parameters influencing lateral stiffness of steel frame with light enclosure wall panels on the applicability of formula,the validity of the formula was proved by using the test data in the literature.The results show that the fitted formula are applicable in different cross-height ratio,axial load ratio,wallboard thickness and wallboard holes.In different width wallboard,it can be multiplied by the width coefficient KB to regulate the influence of the formula by panel width.
