摘　　要：为研究内嵌龙骨LSP板装配式墙体的受力性能,以内嵌龙骨形式为变化参数,开展了6个内嵌龙骨LSP板装配式墙体静载试验。得到了内嵌龙骨LSP板装配式墙体在平面内水平荷载、平面内竖向荷载以及平面外荷载作用下的破坏形态、承载力、荷载-位移曲线和荷载-应变曲线。试验结果表明:内嵌轻钢龙骨LSP板装配式墙体具有较高的承载力和侧向变形能力;加强龙骨构造可以显著提高LSP板装配式墙体在平面内竖向和平面外的承载力、刚度及稳定性,但对平面内水平方向的承载性能影响较小。In order to study the mechanical behavior of LSP board assembled wall with embedded keel,six monotonic static tests of LSP board assembled wall with embedded keel were carried out with the form of embedded keels as variation parameters.The failure mode,bearing capacity,load-displacement curve and load-strain curve of LSP board assembled wall with embedded keel under horizontal load,vertical load within the plane and out-of-plane load were obtained respectively.The test results show that the LSP board assembled wall embedded with light gauge steel keel has higher bearing capacity and good lateral deformation capacity.The reinforced keel structure can significantly improve the bearing capacity,rigidity and stability of LSP board assembled wall both vertical within the plane and out-of-plane,but has little influence on the in-plane horizontal bearing capacity.
