摘要
对实腹式型钢与高强混凝土(C80)的粘结性能进行了试验研究、分析了型钢与混凝土的粘结机理以及影响粘结性能的因素,给出粘结力-滑移(P-△)本构关系和粘结应力分布模式,提出了满足工程精度的粘结力计算公式,并分析推导了临界保护层厚度的计算公式。
Based on the experimental study on the bond behavior between composite steel shape and high strength concrete (C80), the bond mechanism between steel and concrete is analyzed and several parametres which affect the bond behavior are discussed. The relationship between bond force (P) and slip (△ ) and the distribution mode of bond stress are also noted. In order to calculate the bond force, a simplified equation which is satisfactory for engineering precsion is supposed. Moreover, a calculating formula to define the critical concrete cover thickness is proposed.
