| Abstract: | Considering the damage of concrete and steel as well as the condition that materials are deteriorated with time at the same time,the time-dependent computation model of existing bending structure with double reinforced rectangular section is studied according to the design and computing formulas in the code.The simplified calculation formula of time-dependent resistance and time-dependent reliability indexes are also given.This method is applied to an actual engineering project,and the calculation results p... |
