摘    要:通过对12根楔形柱进行静态加载试验,分析和研究楔率及偏心距对楔形柱平面内极限承载力的影响.试件的主要参数为荷载作用的偏心距和楔率.试验在5 000 kN试验机上进行,主要测量了型钢的纵向应变、试件的变形过程、荷载-挠度曲线及试件的极限承载力.试验结果表明,随着楔率的增大,构件的极限承载力也随之增加;荷载偏心距的增大将降低构件的极限承载力.

关 键 词:楔形构件  极限承载力  楔率

Abstract:Based on the test results of the 12 tapering columns under the static loads,the influence of tapering ratio and eccentricity of the axial load on the in-plane ultimate bearing capacity of tapering columns were analyzed.The main parameters of the elements are tapering ratios and eccentricity of the load.All of the tests were carried out in a vertical hydraulic universal testing machine with a capacity of 5 000 kN.The longitudinal strain of steel,deformation process of columns,load-deflection curves of column...
Keywords:tapered columns  ultimate bearing capacity  tapering ratios
