在分析钢筋混凝土空腹夹层板的基本构造及其力学特征的基础上,将其钢筋混凝土下肋网格改为U型钢板组合下肋网格,形成新型钢—混凝土组合空腹夹层板,根据这种新型结构的构造特点,对其U型钢—混凝土组合肋的弹性模量分别用了两种方法“有限元法”和“等效公式法”进行了计算和对比,推导并提出了U型钢—混凝土组合肋的弹性模量计算公式。
Based on the analysis of the basic structure and mechanical characteristics of the reinforced concrete sandwich panel, the lower ribbed grid of the reinforced concrete is changed to the lower ribbed mesh of the U-shaped steel plate to form a new steel-concrete sandwich panel. According to this The structural features of the new structure are calculated and compared with the elastic modulus of the U-shaped steel-concrete composite rib using two methods, the “finite element method” and the “equivalent formula method”, respectively, and deduced and proposed Elastic Modulus Formulas for U - Shaped Steel - Concrete Composite Ribs.
