为研究轴心受压复合节能轻质墙板受力性能,以轴压墙板试验为基础,建立了轴压墙板的有限元模型。通过与轴压墙板试验研究结果进行比较,验证了所建轴压复合节能轻质墙板有限元模型的正确性。利用该有限元模型,探讨了自攻螺钉间距、直径等参数对轴压复合节能轻质墙板承载能力影响程度与规律。通过研究可知,自攻螺钉间距、直径与薄面板强度、弹性模量等参数对墙板轴压承载能力有较大影响。并以此为基础,提出复合节能轻质墙板轴压承载力简化计算公式。
In order to study the stress-bearing capacity of light-weight composite panels with axial compression, a finite element model of the axial-compression wallboard was established based on the test of axial-pressured wallboard. The correctness of the finite element model of the axial compression composite energy-saving lightweight wallboard was verified by comparison with the axial compression wall test results. Using this finite element model, the influence degree and rule of the self-tapping screw pitch, diameter and other parameters on bearing capacity of axial-pressure compound energy-saving lightweight wallboard were discussed. Through the study shows that the self-tapping screw pitch, diameter and thin panel strength, modulus of elasticity and other parameters on the axial load-bearing capacity of wall panels have a greater impact. Based on this, a simplified calculation formula of axial compressive bearing capacity of composite energy-saving lightweight wallboard is put forward.
