[提要]  针对超长体形房屋随季节性温度变化产生较大温度荷载的情况，提出一种底部楼层分缝而上部楼层连接的处理方法，分析了底部分缝的原理，给出了可供实际应用的分缝方法及构造措施，并通过算例验证了该方法的有效性。
[关键词]  温度作用  超长结构  温度缝

For the problem that the superlong structures would be acted by large temperature stress ln the varied temperature during season changing, a new method is presented here that only sets seams at the bottom of structure and connects the upper structure. The new method is based on the theoretical analysis, ancl many substantial ruethods and constructional measures that can be directly used at design work are also introduced. The new method is also verified by the example.
Keywords:  temperature action; superlong structure; temperature joint
