摘要
本文介绍一组钢筋混凝土圆形截面偏心受压短柱的抗裂度及裂缝宽度的试验研究。分析了构件抗裂度与裂缝宽度的主要影响因素。在多元统计回归的基础上，建立了钢筋混凝土圆形截面偏心受压构件抗裂度及裂缝宽度的计算公式。该公式形式简捷，与试验结果吻合良好，且具有一定的精度保证，可用于桥梁基础工程设计。
In this paper,a group of information and data of cracking load and crack widthof R. C circular section member subjected to eccentric compression are given. Main influencing factors on the cracking load and crack width are found by analysis of theory and experiment. Based on the multivariated statistical regression,a set of formulae are proposed.The formulae are simple, identical with the test results,and have proper precision.These formulae may be used in bridge foundation engineering calculation.
