摘要: 木骨架正交斜放竹条覆面墙板的构造特征是把两层正交斜放的竹条钉接在矩形木骨架的一侧，形成一种新型竹木混合预制墙板。为了解墙板在竖向荷载和水平荷载作用下的反应，对木骨架正交斜放竹条覆面墙板进行单向推覆试验，获得了墙板在单向荷载作用下最大水平承载力及水平向的最大变形能力；对木骨架正交斜放竹条覆面墙板进行低周反复试验，研究墙板在地震荷载作用下的抗震承载力、变形能力、破坏过程、破坏形态、滞回曲线和骨架曲线的特征。试验研究表明：木骨架正交斜放竹条覆面墙板充分发挥了竹条力学特性，抗剪性能优良，与轻型木结构相比，墙体的承载能力、刚度、耗能、延性性能均有显著提高，经低周反复试验后的受损墙板最大仍可承受6倍的计算竖向荷载而未发生整体压溃，墙板在严重损坏情况下仍具有较大的竖向承载能力，可用于8度抗震设防的低层建筑的主体结构。Abstract: A kind of hybrid panel, which is made of wooden frame covered by orthogonal oblique placement bamboo strips on one side, was tested. In order to explore the response of the panel under vertical and horizontal load, it was destroyed by the pseudo-static action to measure the ultimate horizontal bearing capacity and deformation capacity. Furthermore, the hybrid panel was destroyed by the low cyclic loading to study its seismic bearing capacity, deformation capacity, failure process, hysteretic curve and skeleton curve feature. The results showed that the bearing capacity, stiffness, ductility and energy dissipation capacity of the hybrid panel were much better than the light wood frame construction because of the hybrid effects between bamboo strips and wooden frame. It was feasible to build low-rise buildings by using hybrid panel as load bearing walls in the 8 degree seismic fortification regions.
