Did the allowable pin shear change in the AISC 13th edition from the 0.22Fu in the 9th edition? If it has or if it is the same, please reference a page #.
thanks
i was looking for a refernce to the operating capacity of a bridge. According to the NBI they are inspected and rated every two years, so i have been trying to find a source that has that information.
sorry for not clarifying. I am working with bridges across the nation that are in varying conditions. Does anyone know where to find capacities for bridges across the US that reflect the current condition of the structure?
Does anyone know where to find the C value in the following equation RF = (C-A1*D) / [A2L(1+I)]
eq. 6B.5.1-1 in the AASHTO Manual for Bridge Evaluation
AASHTO specs out a 0.64klf lane loading for a ten foot width and a single design truck to be applied in a simple span bridge. Does the number of design trucks that are applied to the span change depending on the span?
If it does what is the spacing between them?
References to AASHTO would...
