1 济南轻型钢结构有效的保证了刚架的平面外整体稳定性。若檩条或檩托板孔径过大过长，隅撑就失去了应有的作用。

Jinan's lightweight steel structure effectively ensures the overall stability of the rigid frame out of plane. If the aperture of the purlin or purlin support plate is too large or too long, the corner brace will lose its proper function.

2 隅撑角钢与钢梁的腹板直接连接，当刚架受侧向力时，使腹板在该处局部受到侧向水平力作用，容易导致钢梁局部侧向失稳。

The 2 corner brace angle steel is directly connected to the web plate of the steel beam. When the rigid frame is subjected to lateral force, the web plate is locally subjected to lateral horizontal force, which can easily lead to local lateral instability of the steel beam.

3 有的工程所用檩条仅用电镀，造成工程尚未完工，檩条早已生锈。檩条宜采用热镀锌带钢压制而成的檩条，且保证一定的镀锌量。

Some projects only use electroplating for purlins, resulting in unfinished projects and rusting of the purlins. Purlins should be made of hot-dip galvanized strip steel and pressed, ensuring a certain amount of galvanizing.

4 因墙面开设门洞，擅自将柱间垂直支撑一端或两端移位。同一区隔的柱间支撑、屋面水平支撑与刚架形成纵向稳定体系，若随意移动其位置将会破坏其稳定体系。

Due to the opening of a door on the wall, one or both ends of the vertical support between the columns were moved without authorization. The longitudinal stability system is formed by the support between columns, horizontal support on the roof, and rigid frame in the same partition. If its position is moved arbitrarily, it will damage its stability system.

5 有些单位为了节省钢材和人工，将檩条和墙梁用钢板支托的侧向加劲肋取消，这将影响檩条的抗扭刚度和墙梁受力的可靠性。故施工单位不得任意取消设计图纸的一些做法。

In order to save steel and labor, some units have removed the lateral stiffeners supported by steel plates for purlins and wall beams, which will affect the torsional stiffness of purlins and the reliability of wall beam forces. Therefore, the construction unit shall not arbitrarily cancel some practices of design drawings.

6 有的单位擅自增加屋面荷载，原设计未考虑吊顶或设备管道等悬挂荷载，而施工中却任意增加吊顶等悬挂荷载，从而导致钢梁挠度过大或坍塌。任何单位均不得擅自增加设计范围以外的荷载。

Some units increase roof loads without authorization, without considering suspension loads such as suspended ceilings or equipment pipelines in the original design. However, during construction, they arbitrarily increase suspension loads such as suspended ceilings, resulting in excessive deflection or collapse of steel beams. No unit shall increase the load beyond the design range without authorization.

7 屋面板未按要求设置，将固定式改为浮动式，使檩条侧向失稳。往往设计檩条时，会考虑屋面压型钢板与冷弯型钢檩条牢固连接，能可靠的阻止檩条侧向失稳并起到整体蒙皮作用。

The 7 roof panels were not set as required and were changed from fixed to floating, causing lateral instability of the purlins. When designing purlins, it is often considered that the roof profiled steel plate is firmly connected to the cold-formed steel purlins, which can reliably prevent lateral instability of the purlins and play an overall skin role.

8 刚性系杆、风拉杆的连接板设置位置高低不一，使得水平支撑体系不在同一平面上，从而影响刚架的整体稳定性。刚性系杆与风拉杆构成水平支撑体系，其设置高度在同一坡度方向应保持一致。

The position of the connecting plates for the 8 rigid tie rods and wind pull rods varies, resulting in the horizontal support system not being on the same plane, thereby affecting the overall stability of the rigid frame. The rigid tie rod and wind tie rod form a horizontal support system, and their setting height should be consistent in the same slope direction.
