配筋砌块砌体柱偏压承载力的影响因素分析

利用有限元分析软件ANSYS,对竖向偏心荷载作用下的配筋砌块砌体柱进行了非线性有限元分析,以试验数据为检验标准,在有限元方法得到可靠验证的基础上,进行了扩大参数分析,研究了偏心距、配筋率、高厚比、纵向钢筋位置、配箍率等因素对承载力的影响,为进一步建立和完善承载力的计算方法提供依据。

THE ANALYSIS OF EFFECT FACTORS ON REINFORCED CONCRETE MASONRY COLUMNS UNDER ECCENTRIC LOAD

The general FEA program ANSYS is adopted to simulate the reinforced concrete masonry columns under eccentric compressive load.On the basis of the analytic results agreeing well with the test ones,an extensive parametric study is conducted to analyze the effect of different factors on the bearing capacity including eccentricity,reinforcement percentage,height-to-width ratio,location of the reinforcement,ratio of the hoop reinforcement etc.to give the basis for the new method to calculate the capacity.
