Using this program, different LRFD load combinations are plotted together with the interaction diagram and the design is validated. 1. Introduction and Background For several years American Association of State Highway and Transportation Officials (AASHTO) standard specification [1] has been the main ...

Statistical parameters for resistance and load effects are developed based on strain compatibility theory and stress levels after all losses due to applied loads. Fatigue reliability Indices are obtained using Monte Carlo simulation. ^ Combinations of different spans, concrete grades (girder and deck),...

This thesis aims to compare the design requirements related to design loads, load combinations and strength factors along with section economy comparisons for the design of retaining walls per AASHTO LRFD Bridge Design Specifications, 4th Edition and the AASHTO LFD Bridge Design Specifications, 17th ...
The obtained benchmarked models are then reanalyzed with AASHTO (2010) LRFD factors applied in separate design case scenarios. Each analysis is carried out with both limit equilibrium and non-linear analysis methods. Subsequently, results from all combinations are evaluated and compared. The results ...
