The Numerical Simulation For Wind Pressure On The Roof Of Rhombic Plane And Saddle-Shaped Building

摘要

The existing "structure load code" did not give wind load shape coefficient of rhombic plane and saddle-shaped roof. On this issue, numerical wind tunnel method has significant advantages such as low cost, fasting, collecting more comprehensive results. Using information of CFD and the software of FLUENT, using RNG k-ε turbulence model, simulating a landform rhombic plane, the paper had numerical simulation of average wind pressure coefficient for rhombic plane and saddle-shaped roof building. It focused the effect on the numerical simulation for bending-span ratio. Finally it provided reference for reasonably determining the average wind pressure coefficient of rhombic plane and saddle-shaped roof building.
