| 摘 要： | 密肋复合墙体是建筑结构新体系密肋壁板结构的主要受力构件.提出用复合材料理论对密肋复合墙体的弹性阶段进行结构分析.以Mori-Tanaka的方法为基础,建立了适用于密肋复合墙体的等效弹性板模型,并利用弹性力学对各向异性等效弹性板的抗侧刚度进行了推导.该方法考虑了肋梁、肋柱以及砌块的泊松比对弹性常数的影响及板的各向异性对整体弹性抗侧刚度的影响.结合试验资料对模型进行了验证,结果表明所建立的复合材料等效弹性板模型及其抗侧刚度推导是可行的.

| Abstract: | Multi-ribbed slab structure(MRSS) is a new structural system developed in recent years,with multi-ribbed slab wall as its main bearing member.An analysis of the multi-ribbed slab wall on the elastic stage by means of composite material theory is made.Based on the Mori-Tanaka method,an equivalent elastic slab model adapted to multi-ribbed slab wall is established,and anti-lateral rigidity of orthotropic equivalent elastic slab is deduced by theory of elasticity.The characteristic of this method is that it co... |
