Research Progress on Buckling of Longitudinal Reinforcement Under Earthquake
-
摘要:
在地震作用下，钢筋混凝土结构中的墩柱在承受竖向力的同时，通常还会受到往复荷载作用下的水平力，若结构中横向约束不足，纵筋可能会发生明显的横向变形，使得结构承载力和延性显著降低，修复困难. 因此，研究纵筋在受压时的屈曲机理对结构设计以及施工都有着重要的指导意义. 鉴于此，对基于单根钢筋直压试验的纵筋屈曲研究进行总结，分析得出钢筋屈曲的主要影响因素是长细比和屈服强度；概括总结基于RC （reinforced concrete）短柱直压试验的纵筋屈曲问题的研究进展，阐述在复杂相互作用下纵筋屈曲可能受到的各种影响因素；结合土木发展现状，对使用新材料/新构造的墩柱中的纵筋屈曲研究进行讨论. 现阶段对纵筋屈曲的研究中没有给出判断钢筋屈曲方向和范围的理论方法，对纵筋的整体屈曲以及新型结构中的纵筋屈曲问题仍有待进一步研究，且应在后续研究中综合考虑锈蚀、加载历程、截面形式以及各材料相互作用等因素对纵筋屈曲的影响.
Abstract:During the outbreak of an earthquake, the pier columns in reinforced concrete (RC) structures are usually subjected to horizontal forces and vertical forces under reciprocating loads. When the transverse constraints in the structure are insufficient, the longitudinal reinforcement may have obvious transverse deformation. The bearing capacity and ductility of the structure are thus significantly reduced, and it is difficult to repair. Therefore, it is of great significance for structural design and construction to study the buckling mechanism of longitudinal reinforcements under compression. Firstly, the research on longitudinal reinforcement buckling based on the direct compression test of a single reinforcement was summarized, and the analysis shows that the main influencing factors of reinforcement buckling are the slenderness ratio and yield strength. Secondly, the research progress of reinforcement buckling based on the direct compression test of RC short columns was summarized, and the possible factors influencing longitudinal reinforcement buckling under complex interaction were described. Moreover, combined with the development status of civil engineering, the research progress of longitudinal reinforcement buckling in pier columns with new materials and structures was discussed. Finally, it is concluded that the current research on longitudinal reinforcement buckling lacks a theoretical method for determining the direction and extent of reinforcement buckling. Further investigations are needed to address the overall buckling issues of longitudinal reinforcements and the longitudinal reinforcement buckling concerns in novel structures. Subsequent studies should comprehensively consider the effect of factors such as corrosion, loading history, cross-sectional geometry, and interactions among materials on longitudinal reinforcement buckling.
