aashto-lrfd flexural strength for superstructure tutorial is about flexural strength, compression block depth and minimum reinforcement. in design of precast prestressed girder design, it is necessary to check flexural strength of composite section which is girder and deck. at the ultimate limit state, the loads are magnified,

regarding precast deck, connection details between precast decks are very important because flexural performance of the structures is greatly affected by them. so connection details to secure constructability and safety, profitability are very important. in this study, new connection detail on the precast deck connections is,

standard effective deck properties are typically reported such that the section moduli used for bending are calculated assuming a maximum bending stress in the extreme fiber of the deck equal to the design yield strength (fy) of the deck steel. moments of inertia are typically calculated and reported at a stress level equal to,
type b deck is factory mutual approved. type ba and. bv decks are not factory mutual approved. •. type b, ba and bv decks are manufactured from steel conforming to astm a1008-00 grades c, d or e or from a653/a653m-00 structural quality grade sq33 or higher. the minimum yield strength used by nmbs is 33. ksi.
dura composites supplied over 800m2 of. dura deck type 295 which was chosen because of its' ease of installation. the type. 295 double width planks can halve installation time and have specially designed sub-surface fixings which make it barefoot friendly, uniform and safe for all shoe types. dura deck is produced,
