| Abstract: | Experiments are conducted on six prestressed steel-concrete continuous composite beams.Based on the test results,the internal forces redistribution process and reducing coefficient of internal supporting moment are studied.The formula of reducing coefficient of internal support moment is proposed,which is universal to common continuous composite beams.The calculating results are in good agreement with the measured results. |
