现浇钢筋混凝土结构抗震性能研究

以现浇钢筋混凝土结构抗震性能为研究对象,针对相关问题进行探讨.通过试验,对带有施工缝的钢筋混凝土柱和整浇柱在低周反复荷载作用下的抗震性能进行了研究,对构件的相关实验结果进行了对比分析,研究结果显示施工缝的存在破坏了构件骨料本身的随机分布,在接缝面上形成了薄弱层,降低了柱的承载力和延性.在继续浇筑新混凝土之前,在施工缝处铺一层粘结层可以有效改善施工缝接缝面的性能.

Study on Seismic Behavior of Cast-in-place Reinforced Concrete Structure

The cast-in-place reinforced concrete structure seismic behavior as the research object,according to the relevant problems are discussed.Based on test,with construction joints of reinforced concrete column and RC columns under cyclic loads are studied the seismic performance of structures,the experimental results were compared and analyzed,the results showed the presence of construction joints,destroyed the component aggregate random distribution in itself,on the joint surface form weak layer,reduce the bearing capacity and the ductility of the columns.In continue casting concrete construction seam before,in laying a layer of adhesive layer can effectively improve the performance of construction joint.
