【摘要】 本文采用数值方法计算了一端固定,一端铰支和两端固定时工字形截面钢梁-柱的极限承载力,计算中考虑了各种缺陷因素的影向。本文在大量运算的基础上,以实际计算所得的N/N_p-M/M_p相关曲线为准,提出了验算固端钢梁-柱的建议公式,经计算比较,结果令人满意。更多还原

【Abstract】 A new method and a comoprehensive computer program are developed for calculating the ultimate strength of fixed steel beam-columns. The influence of all initial imperfections is taken into account. On the basis of extensive calculation, a simplified method for checking the stability of fixed beam-columns is presented, and the calculated results show a good agreement with the theoretical values.更多还原
