| Abstract: | The fundamentals of improved robust design method and a new signal to noise ratio are introduced.Parameters reviewed consist of the concrete strength,the yield strength of horizontal hoop and the yield strength of vertical hoop.The softened truss model is applied to predicting shear strengths of exterior RC beam column joints for seismic resistance.And the improved robust design method is applied to analyze several important factors of shear strengths of exterior RC beam column joints for seismic resistance.The results give the degree of importance of different factors.The result of improved robust design method agrees with the testing result better than Taguchi method. It is more accurate and convenient than Taguchi method. |
