| Abstract: | In order to research the wind effects on large cooling towers,one project under construction in India is taken as an example to illustrate the wind tunnel tests and structural analysis of the large cooling towers systematically.The wind tunnel tests mainly include simulation of Reynolds number effect for single cooling tower model,force balance wind tunnel tests of rigid models by 1∶500,and external pressure wind tunnel tests of rigid models by 1∶200.The structural analysis mainly includes finite element analysis on piles,diagonal columns,and shells of the cooling tower,global and local stability analysis,and stability analysis during construction period.Some useful conclusions are given which can be references in the design of other similar cooling towers. |
