Abstract:
Based on the cooling towers' pressure-measured wind tunnel tests of rigid models, finite element model was founded to research the diagonal columns' mechanical property when removing one pair in different positions. The results show that tensile force is dominating in the diagonal columns' all inner forces, and the lee-wind side is the best place to remove one pair of diagonal columns in the temporary period. It is suggested that the removing position should choose the lee-wind side with the smallest wind effect factor based on the wind tunnel tests and the wind speed and direction materials in the field. The convenience in the construction and transportation should also be considered, and the blowing angle in lee-wind side should be collected for smaller group towers' effect factors.
