摘　　要：钢筋混凝土柱补强复合加固技术的研究随着材料科学的不断突破创新和新工艺的发展,近年来出现了混杂纤维复合材料(HFRP)加固技术、预应力钢带加固技术,通过大量的文献检索及综述分析可见,新技术显著提高和改善了钢筋混凝土柱的延性、变形能力和耗能性能、抗剪承载力、抗震性能。In view of the study on composite reinforcement technologies of reinforced concrete columns,with the continuous breaking innovation of material science and development of new processes,the hybrid fiber reinforced plastics(HFRP)technology and the prestressed steel strip reinforcement technology have appeared during recent years,and through a large number of literature search and review analysis,it can be see that the ductility,deformation capacity and energy dissipation performance,shear resistance and seismic performance of concrete columns are increased and improved prominently by these new technologies.
