钢—混凝土组合结构阻裂机理分析

Anti-cracking mechanical analysis on steel-concrete composite structure

分析了钢—混凝土组合结构的阻裂机理,采用平面应力问题的假设,证明了在产生裂纹的瞬间,混凝土与钢板间的粘结力将使裂纹产生巨大的反向应力强度因子,从根本上阻止裂纹的发展,表明了粘结作用的阻裂效果显著。

This paper analyzes the anti-cracking mechanism of the steel-concrete composite structure and by adapting the hypothesis of plane stress problem, shows that the moment cracks occur, the bonding stress between the concrete and the steel sheet will make the cracks produce great reversed stress intensity factor, which will prevent the development of the cracks completely, displaying the outstanding anti-crack performance of the adhesive effect.
