Abstract

Abstract:

Employing Reynolds-averaged method and RNG k-ε turbulent model, wind distribution on curved and open self-weighted roofs with vertical baffle of different sizes under several wind angles are numerically predicted and discussed. Results show that the baffle size and the wind angle have great influence on pressure distribution of the roof. Total shape coefficient of the roof decreases with the increase of the baffle size, as well as the increase of the wind angle. However, the influence on roof pressure by baffle size will decrease with the increase of the wind angle. Thus the structural wind resistive design should be optimized according to practical wind environment, and provide basis on structural design.

Key words: arched roof, wind pressure distribution, computational fluid dynamic, parametric study, optimizational design
