摘要
钢筋混凝土构件受载荷后的破坏,是一个混凝土裂缝扩展、钢筋桥联基体、钢筋与基体脱粘以及钢筋伸长变形直到断裂的过程。根据强化筋桥联基体裂纹的力学分析模型;由变形体的叠加原理和协调性条件,就基体和强化筋材料为完全弹性,裂纹端都存在粘聚力的情况下,用有限元法和叠加法对强化筋的受力进行了计算分析和讨论。
The fracture process of reinforced concrete structure under load includes the following steps one after another: concrete matrix crack starting, the crack extending, steel tendon bridging the concrete crack, the length of tendon deviated from concrete elongating, the tendon and concrete rupturing ultimately. On the mechanics model of crack bridged with reinforced tendon, by the principle of superposition and harmony of solid deformation, the tension force of reinforced bars is calculated and discussed with the help of the finite element method and the method of superposition, under the condition of the base material and reinforced tension material in the range of liner elastic and the condition of cohesive force.
