Abstract:
The distribution function of resistance can be influenced by the prior service loads and which can increase the ability of the existing structures.The proof influence of dead load is prior to that of live load according to the property of dead load and live load,in the paper the proof influence is analyzed which taking into account the ratio between characteristic values of the dead load and live load,prior service period and the degradation of resistance.
