Optimization analysis of steel structure wall stiffeners of petrochemical heating furnace
【Summary】In order to delay the buckling of the wall panel and improve its buckling bearing capacity, it is necessary to arrange a certain number of stiffeners on the wall panel. The current stiffener arrangement on the steel structure wall panel of the heating furnace is difficult to determine with the existing standard calculation methods.

The current stiffener arrangement on the steel structure wall panel of the heating furnace is difficult to determine with the existing standard calculation methods.
Through the establishment of a finite element model for the three-span side of the radiant section of a heating furnace in an actual project for analysis and calculation, it is concluded that applying a horizontal concentrated load at the apex can ideally simulate the deformation of the overall structure under lateral load, which is reasonable The layout of stiffeners can effectively control the out-of-plane deformation of the wall panel, ensure the use of the structure under the design load, and the wall panel will not fail before the main structure. The reasonable layout principle of the wall panel stiffener is determined, and it provides for engineering design. refer to.
