Purpose and Scope 目的和范圍
The objective of this study was to develop a simplified method of predicting the fatigue reliability of steel bridge details with pre-existing cracks. The expected life of a steel highway bridge subjected to random, variable-amplitude traffic cycles is highly dependent upon damage accumulation caused by various fatigue mechanisms. The proposed probabilistic model mainly addresses randomness associated with the stress spectra imposed upon the cracked detail by vehicular passages.
本研究的目的是制定一種簡(jiǎn)化的方法來(lái)預(yù)測(cè)鋼橋的疲勞可靠性和可能存在的裂縫。在公路鋼結(jié)構(gòu)橋受到隨機(jī)、變振幅、周期交通流的條件下,橋梁的預(yù)期壽命很大程度上取決于各種疲勞機(jī)制造成的損害。
Specifically, a method of incorporating inspection data (e.g., the presence and size of cracks) into a fracture mechanics-based fatigue model to predict detail reliabili
