环境温度变化引起钢筋混凝土梁发生变形,当变形受到边界限制条件和构件内部变形不协调的限制条件时,就会产生外部约束应力和内部约束应力。通过分析钢筋混凝土梁温度应力,有助于研究超长框架结构的温度应力问题。
The change of ambient temperature causes the deformation of the reinforced concrete beam. When the deformation is limited by the boundary constraint and the internal deformation of the component, the external constraint stress and the internal constraint stress are generated. By analyzing the temperature stress of the reinforced concrete beam, it is helpful to study the temperature stress of the ultra-long frame structure.
