| Abstract: | Based on the basic assumption of the actual internal forces of appro aching to reinforced concrete beam,the calculating formulas of coefficient of r einforced concrete beam with T-shaped section were presented according to the a nalytical results.The paper also studied the influence of section geomatric siz e changes on ductility of T-shaped section,and compared then with those of rec tangular section.The analytical results can be taken as references for engineer ing designers. |
