【摘要】 本文利用数值积分法,考虑截面残余应力和跨中挠度为千分之一杆长的正弦半波状初弯曲,对50组焊接厚板Ⅰ型和箱形截面柱进行了计算分析,从而确定了该类柱子的稳定曲线取值,以供设计规定参考。更多还原

【Abstract】 In this paper, fifty series of I and box sectional columns welded by thick plates are analyzed with the numerical integration method, which includes the effects of residual stresses and an initial bending of half sine wave whose mid-span deflection is 1/1000 of the span length. Then the φ curve values of this type of columns is determined to give a suggestion for the design code of this type of columns.更多还原
