What kind of steel structure plant suitable for rigid frame
The rigid frame is beneficial to reduce the moment of the lower column and increase the lateral stiffness of the steel structure workshop. Because the column section height is smaller, thereby reducing the steel structure factory building area, but the roof stress is complex, the connection structure also trouble, and the difference of column foundation settlement is more sensitive, so it is suitable for foundation differential settlement is small, heavy steel structure workshop on lateral stiffness requirements are relatively high, especially single span heavy steel structure plant. In the case of single span steel structure workshop, rigid frame is usually used.
1 steel structure workshop with hard hook crane
2 steel structure workshop with two cranes
The 3 is provided with a soft hook heavy duty crane, when lifting Q is larger than 50t, the bottom chord elevation is greater than or equal to 18m;
4 when the steel structure plant height span ratio H/L = 1.5, L = 24m and the span of the steel structure workshop.
Before has heavy roof multi span rigid frame, in order to simplify the calculation especially connection structure improvement in columns and roof truss, had to connect the roof and columns under the vertical load design of plastic hinge (i.e. in roof truss and the colonnade connecting columns made of plastic deformation on tensile sit under the action of. However, the pressure can still be transferred, under horizontal load. One end is connected with the school roof, the other end is rigid. This method can simplify calculation and structure, but does not affect the lateral stiffness of the frame, is advantageous in the heavy roof, now most have adopted multi-span workshop school next frame, the less used, layout and structure of the plastic hinge.
