Time Variable Reliability Analysis for Old Concrete Bridge Using the Response Surface Method
The concrete strength and steel rod strength degradation gives rise to concrete bridge bearing capacity failure. The influence of the concrete carbonation and the induced rebar corrosions and the resist force function degradation with time elapsed were studied. The bridge member resisting force as a function of service was investigated using the time variable strength model. The statistical bridge live load model is considered in the analysis. The OpenSees reliability analysis module was applied in the analysis. The evolution of the reliability was obtained. The proposed method was applied in an old concrete bridge time variant reliability analysis.
