| 摘 要： | 钢筋锈蚀威胁建筑物的抗震能力,利用ANSYS有限元分析软件,建立钢筋锈蚀前后完好结构和锈蚀后结构2个模型,进行多遇地震的时程分析.结论表明,钢筋锈蚀层对杭震有耗能作用,但结构动力响应中位移变大、剪力变小,较大的钢筋锈蚀率明显降低了钢筋混凝土框架结构杭震性能.

| Abstract: | The steel bar corrosion threatens the seismic capacity of the reinforced concrete(RC) structures in coastal zones.In this paper,the ANSYS software is used.The model of RC structure and deteriorating RC structure is established.The time-history seismic analysis of frequent earthquake is carried on.The conclusion shows that the hysteretic energy of the corroded bar helps the seismic capacity of the RC structure.And the displacement increases and the shear capacity reduces in the earthquake response.The big ra... |
