高强螺旋箍筋约束混凝土柱连接抗震性能试验研究与理论分析
Seismic behavior experimental study and theoretical analysis on high-strength spiral stirrups confined concrete column
摘要
Abstract
Abstract:For high strength stirrup confined concrete columns of the frame structure,a new column-column connection is put forward where the local wrapping steel tube and bolting bars are used.The full-scale prefabricated columns and cast-in-place column specimen were produced and experiments of specimens under quasi-static cyclic reversed loading were carried out.The force,deformation,failure process and failure mode of specimens were observed and its load carrying capacity,deformation capacity and energy dissipation capacity were analyzed.The reliability of the new connection was verified.The result of experiments shows that high-strength spiral stirrups confined of concrete monolithic columns and cast-in-place columns have the same excellent seismic performance under high axial compression ratio.The assembled monolithic compound spiral reinforced concrete columns can be adopted in high seismic zones instead of cast-in-place columns.According to the test,the mechanical behavior of a new type of connection was analyzed,and the calculation formula of yield load and maximum load are put forward.By comparing the calculation results and test results,the correctness of the theoretical formulas was verified.关键词
