Abstract:

In the calculation of uhimate axial compression ratio for irregularly-shaped columns,the grid method is usually applied to the cross-section integration.In order to overcome the dificulty in d division,this paper proposes a simplified calculation method of the uhimate axial compression ratio without the grid division of cross-see-tion.On the basis of plane assumption,a new and simple CroSS-section Gauss integration method is adopted to numerically analyze the ultimate ax ial compression ratio for reinforced concrete iregularly-shaped columns,with cotresponding software being finally programmed.It is found that the theoretical analysis results are in good agreement with the ones presented in literature,and that the P method is simple,accurate and needless to iterate.

Key words: iregularly-shaped column, uhimate axial compression ratio, simplified calculation, across-section Gauss integration method
