| 摘 要： | 提出该结构体系在水平载荷作用下，可视为夹层复合构件，并提出了计算模型. 根据
变形协调原理对其进行受力分析，建立了多层多跨密肋复合墙体结构横向位移及各组成构件承
受剪力和弯矩表达式. 通过计算分析指出，各组件剪力分配只与各组件刚度及宽度比有关，
内墙板上部分配剪力大于下部，边框反之；各组件局部弯矩系数随$\lambda
$的增加而减小，其整体工作性能增强，当$\lambda
$增加到一定数值时，其工作性能与悬壁构件类似.

| Abstract: | Taking the structure system as a sandwich composite
element, a calculation model is proposed, and the lateral displacement of the
structure, shearing force and bending moment of the components
are obtained according to deformation compatibility. The
calculation analysis shows that shear force distribution of components is
only related to with stiffness and width of components, and shear stress
in upper internal composite slab is larger than that of lower slab;
bending moment
distribution coefficient of components decreases as $\lambda $
increases, and whole structure is strengthened, and when $\lambda $ is enough
large, mechanical behavior of structure is similar to a cantilever member. |
