轻型门式刚架结构优化设计

Optimization Design of Portal Frames

轻型钢结构已被广泛使用,本文针对工程实际情况详细论述了轻型门式刚架结构的设计方法,突破常规设计中采用6m或9m来确定柱距的做法,优化柱距方案.同时采用了更符合刚节点力学模型的连接方式,横梁采用了变截面方案,以达到节约钢材的目的.

According to The actual intance, the traditional module of 6m and 9m for the column spacing is broken through and a new scheme of the column spacing is put forward. Morver, It is adopted that a new jiontingmethod which is better to accord with the rigid joint mechanics model.The non- uniform beam plan is adopted in order to save material.
