beam and girder slab

Through integrating the steel girder and the concrete slab with shear connectors, steel-concrete composite beam has been widely used in the structural and bridge engineering.

钢-混凝土组合梁是钢梁和混凝土板通过剪力连接键连接而成的组合结构，在现代结构和桥梁工程中得到了广泛的应用。

The interface between concrete slab and steel girder was simulated as Goodman nonlinear elastic sandwich. The relationship between the slip, deflection and load of double composite beam in elastic state was analyzed by Goodman elastic sandwich method.
