摘要
采用经典层合梁理论分析了钢板在结构中对裂缝阻碍的作用,证明了在结构受拉区设置钢板可以更充分的发挥钢材的作用,使得钢板与混凝土共同受力,起到阻碍受拉区域混凝土裂缝产生的作用。
Using the principles of the laminated beam to analysis reason of the steel plate for anti-crack performance. This paper proved that using the steel plate in the structure tensile area will fully develop function of steels, and make the concrete and steel stressing together. And impede anti-crack developing in the concrete tensile area.
