| Abstract: | In the chemical tower equipments, plate column downcomer, as the main support structure, plays a key role in the static and dynamic performance of the whole tray panel. Ac- cording to the types of downcomer and loads behavior, the finite element model of plate column downcomer has been estimated. The stiffness and strength of structure was studied. The ribs were used to improve the stiffness of structure. The topology optimization method was used to determine the location shape and number of the ribs. The influence on the thickness and height of ribs was discussed. The results may provide the guide for the design of the ribs in the plate col- umn downcomer. |
