摘　　要：应变率效应会导致钢筋和混凝土材料的动力增强。文章结合腐蚀钢筋混凝土的力学性能削减,参照《混凝土结构设计规范》(GB 50010—2010)中圆形墩柱正截面极限状态承载力计算公式,根据塑性铰的能量守恒定律,推导得出腐蚀墩柱受侧向冲击作用下正截面破坏状态的计算公式。Strain rate will enhance the dynamic of steel and concrete materials.By combining with the reduction of mechanical property of corroded reinforced concrete and referring to calculation formula of limited state bearing capacity of circular pier normal section in Code for Design of Concrete Structures(GB 50010—2010),according to energy conservation law of plastic hinge,this paper deducts calculation formula of normal section under failure state of corroded reinforced concrete piers under side impact.

关 键 词：应变率 腐蚀 冲击力 能量守恒
