If the floor is not sufficiently rigid to transform the loads, a horizontalbracing system must be provided between bents.
如果楼面没有足够的刚度去传递这些荷载。那么还必须在排架之间增加水平支撑系统。

Roof purline is adopted with cold-bending and thin-wall steel (Q345), knee bracing, roof horizontalbracing and purline drawn rod Q235.
本工程屋面檩条采用高冷弯薄壁型钢材质Q345，隅撑，屋面水平支撑，檩条拉条材质均为Q235。

Some problems are discussed, such as the mechanical mode and equivalent stiffness of horizontalbracing system, the deformation compatibility between the bracing and retaining wall.
