不管是搭建厂房还是车间，大都会选用钢结构材料，在使用轻型钢结构施工时，该怎么减少用钢量呢？下面详细了解下。

Whether building workshop or workshop, most of them choose steel structure materials. When using light steel structure, how to reduce the amount of steel used? The following details.

一、长与宽的选择

I. Choice of Length and Width

一般来说，在布置柱网时应遵循长度大于宽度的原则，能减轻轻型钢结构用钢量，同时也能减少柱间支撑的风荷载，从而降低支撑系统的用钢量。

Generally speaking, the principle that length is larger than width should be followed in the arrangement of column network, which can reduce the steel consumption of light steel structure and the wind load of the support between columns, thus reducing the steel consumption of the support system.

二、柱距选择

2. Pillar Spacing Selection

标准荷载作用下的经济柱是8-9m，超过9m时，屋面檩条与墙架体系的用钢量增加太多，综合造价并不经济。

The economic column under standard load is 8-9m. When it exceeds 9m, the steel consumption of roof purlin and wall frame system increases too much, and the comprehensive cost is not economical.

三、合理跨度的确定

3. Determination of Reasonable Span

不同的生产工艺流程，和使用功能在很大程度上决定着跨度，一般根据自己的使用功能，确定较为经济的跨度。在尽可能满足生产工艺和使用功能上，应根据房屋的高度确定合理的跨度。一般情况下，当柱高、荷载一定时，适当加大跨度，刚架的用钢量增加不太明显，但节省空间，基础造价低，综合效益较为可观。

Different production processes and use functions determine the span to a great extent. Generally, according to their own use functions, a more economical span is determined. In order to satisfy the production process and use function as far as possible, the reasonable span should be determined according to the height of the house. Generally speaking, when the column is high and the load is fixed, the steel consumption of the frame increases slightly when the span is increased appropriately, but the space is saved, the cost of the foundation is low, and the comprehensive benefit is considerable.
