单层框架结构温度应力分析的静力平衡法

The Static Banlance Method of Temperature Stress Analysis of Single-story Frame Structure

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。

Changes on temperature could cause stress in con-crete ,and the resulting carck will undermined the durability of concrete structure, even endanger the safety of structure. For a single - story frame structure, a calculation formula was deducted by the static banlance method and the mechanical model of frame structure was simplified based on three assumptions.
