A simulation for computational fluid dynamics is carried out to predict wind pressure coefficients for cladding. The simulation is carried out against a low-rise building for cladding and the results are compared with the field data, wind tunnel experimental data, and those obtained by the computational simulation using CFD by means of Smoothed-particle hydrodynamics(SPH). SPH is a computational method used for simulating fluid flows It is a mesh-free Lagrangian method, and the resolution of the method can easily be adjusted with respect to variables such as the density. The CFD simulation by means of the mesh-free Lagrangian method based on SPH was used a commercial tool. It is found that the predicted wind coefficients agree well with the reference data. According to thus results, it is compared and analyzed the wind pressure coefficients over low-rise building for cladding.
