[提要]  对钢筋混凝土框架结构超过规范所规定的伸缩缝最大间距的温度变形与温度应力进行了研究，并提出了一个概念清楚、计算简便的计算方法，对设计有一定实际意义。
[关键词]  超长框架结构 温度变形 温度应力 抗剪刚度

The temperature deformation and stress of ultralong frame structure are discussed, in which the space of telescopic joint is beyond the scope of China's concrete structure design code(GBJ 10 - 89). The suggested method is clear in conception and convenient in calculation, which has a practical significance for disigning.
Keywords: ultralong frame structure; temperature deformation; temperature stress; shear rigidity
