摘要
介绍了空间网架温度应力的计算方法,分析了边界约束对网架受力的影响,说明在工程设计中应考虑支承平面内杆件的温度应力并合理设计网架的支座形式,以满足计算假定、协调上部结构与下部支承的受力和变形。
It introduces calculation method of temperature stress of spatial grid and analyzes influencing of boundary constraint, and illustrates it should consider temperature stress of plane pole and design reasonable supporting block of grid to calculate stress and deformation of upper structure and under support.
