Two lanes loaded, there will be a constant value LF2. There’s one lane loaded, there will be a constant value LF1 if there’re Per design criteria, we have to consider train longitudinalĪcceleration & deceleration load (call it LF) along with the live I’d like to find the stress at the footing calculatingįrom the concurrent vertical reaction FZ, longitudinal moment MY, and transverse The abutment consists of backwall, stem, and footing at the bottom. Spans are supported by the abutment as shown. Let me explain what I need to do first and see if you have better suggestions.įirst of all, the model consists of 2 spans, and these 2
