The design process becomes complicated due to combined force effect, LRFD crash test level requirement and the existence of several load combinations. Using this program, different LRFD load combinations are plotted together with the interaction diagram and the design is validated. 1. Introduction and...

The girders are designed based on the current AASHTO LRFD Bridge Design Specifications 2010. ^ The four types with the greatest maximum spans of the six Types of AASHTO Girders are considered. The girders are analyzed and designed according to latest code, Strength Limit State and Serviceability ...
the bridge may be proportioned such that either of the following criteria are satisfied: where: W = the weight of the supported structure, including only dead load (kips) f = the fundamental frequency in the vertical direction (Hz) 7.1-HALF-THROUGH TRUSSES 7.1.1-Lateral Frame Design Force Th...
multiplied by the appropriate load factors specified for the load combination under consideration. Factored Resistance --The nominal resistance multiplied by a resistance factor. Fixed Bridge --A bridge with a fixed vehicular or navigational clearance. Force Effect --A deformation, stress, or ...
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 ...
This paper presents the reliability analysis of NU girders designed using the strength I limit state of the AASHTO LRFD bridge design specifications. Resistance models are developed for several types of NU girders (NU1600, NU1800, and NU2000) and considering different combinations of girder span (...
