| Abstract: | Taking the computation practice of a prestress-strengthened RC beam's deflection as an example,limit state equation for this deflection computation is established with Improved JC Method and the reliability index of the computation is obtained after four iterative trials.And the comparison of reliability index obtained by Improved JC Method with that by JC Method indicates that the former one is more accurate. |
