摘要:

为研究压弯荷载作用下复合节能轻质墙板横向水平受力性能,以墙板压弯试验为基础,建立了压弯墙板有限元模型。通过与墙板试验结果进行比较,验证了有限元模型的正确性,并利用该有限元模型,探讨了自攻螺钉间距、自攻螺钉直径、薄面板强度、薄面板弹性模量等参数对压弯墙板横向水平承载力的影响程度与规律。以此为基础,提出了压弯荷载作用下复合节能轻质墙板横向水平承载力简化计算公式。结果表明:自攻螺钉间距、自攻螺钉直径与薄面板强度、薄面板弹性模量等参数对压弯墙板横向水平承载力有较大影响。

Abstract:

In order to study the mechanical behavior of light weight energy-saving composite wall under vertical and lateral loads, the finite element models of composite wall were established based on the composite wall specimen test. The finite element models were verified rationally and correctly in the paper, through comparing with the composite wall test results. The finite element model was used to analyze the load bearing capacity of composite wall. Various factors affecting degree and rules of performance of composite wall with simply supported end were analyzed, such as the span of self-tapping screw, the diameter of self-tapping screw, the strength of thin panel and the elastic modulus of thin panel, etc. The calculated formula of lateral load bearing capacity of composite wall under vertical and lateral loads was proposed. The results show that the lateral load bearing capacity of composite wall increases with the increase of the span of self-tapping screw, the diameter of self-tapping screw, the strength of thin panel and the elastic modulus of thin panel, etc.
