温度变化会在混凝土内部产生应力,由此产生的裂缝严重影响混凝土结构的耐久性甚至危及结构安全。以单层框架为研究对象,基于三个假定简化框架结构力学模型,通过静力平衡法推导出单层框架结构温度应力的计算公式。
Temperature changes can cause stresses in the concrete. The resulting cracks seriously affect the durability of the concrete structure and even endanger the safety of the structure. Taking the single-layer frame as the research object, the formula for calculating the temperature stress of the single-layer frame structure is deduced by the static equilibrium method based on three hypotheses to simplify the mechanical model of the frame structure.
