摘　　要：网架结构广泛应用于大型公共建筑物和工业建筑中,其合理的用钢量不仅使得结构受力合理,而且可以节约钢材,符合可持续发展的要求。因此,针对36 m×42 m跨度的上弦周边支撑网架,计算了8种高度,采用数学拟合的方法,探究网架跨高比与单位面积用钢量、节点自重占比、杆件规格用钢量等参数之间的规律关系,进而确定了最优跨高比,并提出了相关设计建议,可以为工程设计和规范修订提供一定的参考。The grid structure is widely used in large public buildings and industrial buildings.Its reasonable steel consumption not only makes the structure stress reasonable,but also can save steel and meet the requirements of sustainable development.Therefore,in this paper,eight heights are calculated for the 36 m×42 m span top chord surrounding support grid.By using the method of mathematical fitting,the relationship between the span height ratio of grid structure and the parameters such as the steel consumption per unit area,the proportion of node self weight,the steel consumption per member specification is explored,and then the optimal span height ratio is determined,and relevant design suggestions are put forward,which can provide engineering design and code revision certain reference.
