密肋复合墙体有效面内剪切模量的计算

RESEARCH ON AN EQUIVALENT MATRIX-INCLUSION COMPOSITE SLAB MODEL FOR A MULTI-RIBBED SLAB WALL

密肋复合墙体结构是近年来发展的一种建筑结构新体系,密肋复合墙体是密肋复合墙体结构的主要受力构件。采用复合材料方法对密肋复合墙体的弹性阶段进行力学分析,以有效自洽法(ESCM)和相互作用直推法(IDD)为基础,把墙体视为基体-夹杂型复合材料弹性板,推导密肋复合墙体有效面内剪切模量的计算公式,结合试验资料对计算模型进行验证。结果表明,建立的基体-夹杂型复合材料等效弹性板模型是可行的。

Multi-ribbed slab structure （MRSS） is a new structural system developed in recent years, with multi-ribbed slab wall as its main bearing member. Analysis of the multi-ribbed slab wall on the elastic stage by means of composite material theory is made. Based on the ESCM and the IDD methods, an equivalent elastic slab model adapted to multi-ribbed slab wall is established, and in-plane effective shear moduli of orthotropic equivalent elastic slab is deduced. By testing the model and analyzing experimental data, the composite material equivalent elastic slab model is feasible.
