| 摘 要： | 钢结构通廊在工业领域有着广泛的应用,工程设计中常将其简化为平面桁架进行计算。结合一实际工程,对下承式通廊进行空间计算,探讨弦杆轴向变形对纵向支撑和平台梁的影响。分析结果表明:通廊纵向支撑和平台梁的计算应考虑弦杆轴向变形的影响。最后采用虚功原理推导出根据弦杆轴力计算纵向支撑内力的公式,该公式适合于平面简化计算,可供工程设计参考。

| Abstract: | Vestibule of steel structure is widely used in industry,and usually calculated with the model of simplified plane truss.In this paper,an under-supported vestibule is spatially analysed with a practical engineering.The influence of chord deformation on longitudinal brace and platform beam are discussed.The conclusions show: the impace of chord axial deformation should be taken into account for the calculation of the longitudinal brace and platform beam.Finally the formula of computing longitudinal brace forc... |
