Numerical wind tunnel simulation of wind resistance for tower structure of high-rise ship lift
摘要
Abstract
In this study, numerical wind tunnel simulation technology was used, the incompressible Navier-Stokes equations for viscous fluids were employed to describe the motion of the wind, and appropriate boundary conditions for the computational domain were established. In this way, a new method for wind resistance analysis for a tower structure of a high-rise ship lift was developed based on the ADINA software for finite element analysis. The correctness and validity of this method were verified with an example. Combined with a project case, the wind-induced response of the ship lift tower structure was analyzed, and the wind-load shape coefficient of the ship lift tower structure was obtained, the expression of the downwind vibration coefficient of the ship lift tower structure was derived, and the calculated wind-load shape coefficient and downwind vibration coefficient were compared with the results obtained from the specification. Numerical simulation results show that the downwind maximum displacement of the high-rise ship lift tower structure occurs near the top of its windward side. The wind-load shape coefficient of the ship lift tower structure obtained from the numerical wind tunnel simulation technology is greater than the result obtained from the specification. The downwind vibration coefficient obtained from the specification is lower than that obtained from the numerical wind tunnel simulation for the whole region, except in the region below the elevation of the structure of 90 m.关键词
