At first,the feasibility of using numerical simulation method to analyze building shape coefficient is verified by comparing the results of the wind tunnel test with it. Then the roof shape coefficients of L-shape and rectangular gable buildings are compared,and the shape coefficient of the rectangular roof is compared with that in standard. The results show that the roof shape coefficients of L-shape buildings are relatively smaller under most of the working conditions,which means that the L-shape buildings are more advantageous for wind resistant. The results also point out that the shape coefficients in the norm are small when the number is negative. Finally,the shape coefficient values which are used to calculate L-shape buildings based on test values are suggested.
