Abstract:

AASHTO LRFD (2010) requires combined live and thermal load effects for the service ; limit state design. The Design Procedure described in the appendix will follow the ; rationale developed by Ulku et al. (2009). Link slab design moments are calculated using ; the girder end rotations. HL-93 loading is used to calculate the girder end rotations under ; live load. Girder end rotations caused by the temperature gradient are calculated using ; the procedure described by Saadeghvaziri and Hadidi (2002) by ensuring strain and ; curvature compatibility among sections and reinforcements. ; One major improvement in the process presented in this appendix compared to what is ; given in Ulku et al. (2009) is the inclusion of 3D and skew effects to calculate the ; resultant link slab design moments and forces. ; In order to apply loading, the first step is to establish a composite girder-deck crosssection ; with an effective width as per AASHTO LRFD (2010) Section 4.6.2.6, the ; composite moment of inertia, and the modulus of elasticity for concrete.
