复合墙板轴心受压试验研究

Experimental Investigation on Composite Wall Panels under Axial Compression

进行4组12片复合墙板轴心受压试验研究,对破坏过程及破坏形态,试件的荷载侧向挠度曲线复合墙板承载力及稳定性等试验结果进行对比分析.分析表明,墙板受力性能良好,通过斜拉筋连接的两侧混凝土能够很好的共同工作,复合墙板具有较高的轴心受压承载能力和可靠的稳定性,不会发生失稳破坏.最后,得出相应的承载力及稳定性计算公式和计算方法,结论可供设计参考.

The axial compression experiments for twelve pieces of composite wall panels in four groups were carried out. Experimental results, such as processes and modes of failure, load-deflection curves, bearing capacity and stability of the composite wall panels etc. , are analyzed comparatively. It＇s indicated~ the load bearing behavior of the composite wall panels is very good, two pieces of concrete plates connected with the oblique tension steel bar can work in coordination very well, the composite wall panels have quite high axial compression bearing capacity and reliable stability, and instability will not occur. The formulas for calculating bearing capacity and stability are obtained. The conclusions are worthy of design reference.
