摘要
对冷弯薄壁型钢骨架粉煤灰陶粒混凝土墙板进行了轴压和偏压试验,获得了竖向荷载-位移曲线,分析了墙板位移随竖向荷载的变化规律,得到了墙板极限承载力;对墙板抗压刚度进行理论分析计算,通过与试验结果相比较,确定此类墙板的抗压刚度计算公式。
Axial compression and bias tests of cold-formed thin-walled steel frame fly ash eeramsite concrete wallboard are carried out.The load displacement curve is drawn and the variation of wallboard displacement with vertical load is analyzed.The ultimate bearing capacity of wallboard is obtained.The theoretical analysis and calculation of the compressive stiffness of the wallboard are carried out,and the formula for calculating the compressive stiffness of such wall panels is determined through comparison with the test results.
