| Abstract: | In order to objectively reflect the influence to bearing capacity from the factors like material degradation,structure damage,operating environment change and the working state change of structure and so on,the bridge strengthening calculus characterisitc is analyzed.Bearing capacity computing formula of normal section and inclined cross-section of R.C.beam-type bridge is geven here.The general procedures of strengthening calculation based on damage and degradation model are represented and are used by an engineering example to indicate the calculation method. |
