摘要

摘要: 为了研究高强箍筋约束高强混凝土柱的抗轴压性能,定量分析该类型柱的强度和变形提高程度,进行了31根高强箍筋约束高强混凝土方形截面柱的轴心受压试验。在试验的基础上,分析箍筋强度、箍筋间距和箍筋形式对其强度和变形性能的影响;结合国内外试验数据,通过回归分析提出高强箍筋约束高强混凝土峰值强度和极限应变的计算公式。

Abstract: The objective of this study is to study the axial compression performance,including strength and deformation behaviours of HSC columns confined by high-strength stirrups,and determine experimentally and analytically the magnitude of its strength enhancement.On the basis of a concentric loading test of 31 HSC columns confined by high-strength stirrups,the influences of the tie yield strength,tie spacing,and tie configuration on the characteristics of strength and ductility were evaluated;based on the test data at home and abroad,the formulas to determine peak strength and ultimate strain of high-strength concrete confined by high-strength stirrups were proposed by regression analysis.
