摘要
在刚架温度内力的分析中，本文提出两种计算温升内力的方法，并证明了它们的一致性，探讨了轴向变形对温度内力的影响，确定了影响温度内力的因素，估计出工程上温度内力计算方法的精度。
Two methods of calculation arc presented for analysing the thermal stress of rigid frames and their coincidence is shown in this paper. The effect of axial deformation on thermal stress is explored. Three illustrated examples are used in determining the influ- encing factors of thermal stress and evaluating the precision of the method used in engineering for calculating the thermal stress of rigid frames.
