摘要
根据屈服线理论,研究柱下独立基础的抗弯强度,求出其在轴心受压和偏心受压时由于弯曲破坏的极限荷载,提出抗弯强度计算公式与设计建议,指出现行抗弯强度计算方法和公式偏于不安全和误差,并进行了分析.
Based on yield line theory, analysis of single foundation under column for flexural strength is done. Ultimate load of the foundation for bending failure is calculated while the column is subjected to axial compression or axial bending and compression. It is pointed out that the methods and formulae used in current practice for flexural strength of the foundation are unsafe and erroneous. Effective facfors on error and quantity of error are studied.
