网架与钢屋架的技术经济分析

设计方案的技术经济分析是广大设计人员的一项经常性任务。由于缺少网架与钢屋架的技术经济分析资料，设计人员只能从两种结构的特点分析着手，使设计方案的确定缺乏应有的说服力。本文经济分析比较给出了常见矩形平面周边支承情况下网架与钢屋架的技术经济指标，可供有关人员在选择方案时参考。

Technic and Economic Analysis in Grid Space-Framed Steel Structure and Steel Truss Structure

The technic and economic analysis of designing plan is a regular job for de- signers. Because of lack of analysis data in this field,the designers work only from the analysis of these two structural properties,so that it couldn't have enough convincing to determine designing plan.By analysing and contrast,under the condition of a four-side supportted common rectangle plane,the technic and economic index of grid space- framed steel structure and steel truss structure is given in the paper,which can be ref- ered to the relative persons who determine designing plan.
