【摘要】 本文对原有的“逆算单元长度法”进行了适当的改进,并编制了相应的计算程序.计算表明:改进后的逆算单元长度法计算效率明显提高.同时,本文计算所得的等端弯矩作用下工字形截面和双角钢T形截面的N/N_P-M/M_P相关曲线可供设计参考,具有一定的实用价值.更多还原

【Abstract】 This paper presents an improvement on“the inverse calculationsegment length method”,and compiles computer programs for ultimate strength ofbeam-columns under equal moments at both ends.The limiting strengths of I se-ction and double-angle T section beam-columns are calculated,and forty interactioncurves of N/N_p-M/M_p are plotted.These curves are of some value to practical design.更多还原
