摘要:
在锈蚀混凝土框架结构耐久性损伤分析的基础上，对锈蚀钢筋混凝土压弯试件的抗震性能的试验结果进行了探讨，分析了锈蚀试件滞回曲线和骨架曲线的特点，建立了锈蚀钢筋混凝土框架结构动力反应分析模型，用Wilsonθ法编制锈蚀混凝土框架结构计算程序，对钢筋混凝土框架在不同的钢筋锈蚀率及不同锈蚀层数下的地震反应进行了对比分析，计算结果表明，钢筋锈蚀将导致混凝土框架结构的抗震性能降低严重、地震反应加大.并指出底层柱的钢筋锈蚀对混凝土框架结构抗震性能的影响至关重要.
Abstract:
Base on the analysis of damage durability for corrosion concrete frame structure, compression and bending corroded reinforced concrete specimen seismic performance were studied, analyzed the characteristics of corrosion of the hysteretic curve and skeleton curve, the a dynamic compute model of corroded reinforced concrete frame structure has been established. The calculation program of the concrete plane frame has been compiled with the Wilsonθ method, and the comparative analysis for different frame of reinforced concrete has been calculated in earthquake response under different bar corrosion rates and different corrosion layers. The calculation results show that the seismic performance of concrete frame structure reduce serious and earthquake response increased in the wake of Re-bar corrosion. And pointed out that the bottom column reinforced concrete frame structure is very important for seismic performance.
