We put the concrete flange plate of the composite beam into the steel ones according to the elasticmodulus ratio and keep the width of section unchanged, as a result, get a equivalent section.
将组合梁中混凝土翼缘板厚度按弹性模量之比换算，并保持宽度不变形成等效截面。

The bending stiffness of elastoplastic member is product of tangent elasticmodulus of material and inertia moment of the section.
抗弯刚度的概念是材料切线模量和截面对中和轴的惯性矩的乘积。

Consequently the crack on the wall is begot. The crack is concerned with horizontal resistance coefficient, temperature, size of wall section, elasticmodulus.
