摘要： 桁架考虑轴向力效应。本文用正弦级数与多项式推导杆件的角变位移方程式。为了克服级数收敛缓慢的缺点,提出级数求和公式。利用这些公式计算了桁架考虑轴向力效应时的次应力,精度高,经济效益好。
Abstract: Let us consider the axial forces effect of truss. This paper uses sine series and polynomial to derive the bar of slope deflection equations. In order to overcome the demerit of the slowness of the series convergence, we put forward the series summation formula. These formulas calculate secondary stresses of truss at high accuracy and good economic utility.
