钢与混凝土组合梁中混凝土翼板适宜厚度的确定

The method to calculate the concrete flange plate thickness of the composite beam

组合梁是钢梁和其上混凝土翼板共同抗弯的一种构件。为充分利用混凝土的抗压性能 ,本文通过分析钢与混凝土组合梁使用阶段的应力分布 ,提出了一种确定钢梁上混凝土翼板厚度的方法。通过实例核算可保证结构的安全可靠。

The composite beam is a component comprised the steel beam and the concrete flange plate on the steel beam.In order to fully used the compression resistance of the concrete,this paper analyzed the stress distribution to the composite beam in the actual use,and put forward to the method calculating the concrete flange plate thickness.Through the verification,the structural safety and reliability are assured.
