this report provides guidance on the design of steel-concrete composite bridges, which consist of steel girders and reinforced concrete slabs on top. two common forms are considered: multi-girder and ladder deck bridges.
wisdot bridge manual chapter 30 railings july 2019 30-5 30.2 railing application the primary purpose of bridge railings shall be to contain and redirect vehicles and/or pedestrians using the structure. in general, there are three types of bridge railings traffic railings, combination railings, and p edestrian railings.
design standards and specifications. design standards for this project will conform with manual of standard and specifications for two laning of state highways : sp:73 irc-2007 , specification for road and bridge work by government of india, morth and various relevant irc standards and bis standards.
bridge deck shall provide curbs, railing, drainage, and joint seals as required. pavement of deck shall extend 20 ft. past the end of the structure and be placed over a 12-inch thick minimum base.

frp composites in bridge design. ngcc has an frp bridge design group producing design guidance on frp bridge design -eurocode aligned -aims to plug the gaps in current standards and provide best practice guidance -focus on principles and failure criteria to be covered.
bridge and continuous across the width of the span. in most applications, the bridge deck is made composite with the steel superstructure through positive attachment to the girders, such as using shear connecters to attach the concrete deck slabs to steel girders. in such cases, the deck
bridge railing design aashto ca13.3.1 in this analysis it is assumed that the yield line failure pattern occurs within the parapet only and does not extend into the deck. this means that the deck must have sufficient resistance to force the yield line failure pattern to remain within the parapet.
the best material selection is: steel bridge with a fiberglass bridge deck. robust, extremely durable, immune to water ingress, de-icing materials and superior to concrete decks . concrete weighs 5x more than fiberglass. fiberglass allows pre-assembly on site, then install using lighter cranes than concrete.
the useful life extension of existing bridge superstructures with lightweight frp bridge decks; composolite composolite is a patented advanced composite building panel system suitable for major load bearing structural applications. the modular construction system consists of a small number of interlocking fiber reinforced polymer frp structural components produced by the pultrusion process.
our zero maintenance, high-strength standard trail bridges last up to 100 years. we combine a fiber reinforced polymer frp deck with weathered steel beams and aluminum railings to provide bridge systems that can resist salt, water and chemical corrosion. our sustainable products also complement their natural surroundings. costs are reduced.
the perfect material. the incredible durability of bedford structural fiberglass in a variety of weather conditions makes it the ideal choice for constructing pedestrian bridges. resistance to heat, high winds, rain, snow and corrosion are why more and more locations are replacing failing old wood and steel bridges with m e 2 pedestrian bridge solutions from bedford.

railings bridges composite bridge deck design . these loads to the steel superstructure. the deck is typically continuous along the span of the bridge and continuous across the width of the span. in most applications the bridge deck is made composite with the steel superstructure through positive attachment to the girders such as.
pedestrian frp bridge decks. we design and manufacture our frp bridge decks to the unique performance requirements of your pedestrian bridge project. design flexibility means fiberspan decking works with any superstructure configuration and incorporates all design features including crowns, cross-slope, skews, curbs, drain scuppers, non-slip overlay and railing attachments.
the very first all-composite bridge in the country was the no name creek span, placed in russell, kan. in november 1996 see ct january/february 1997, p. 7 . the cored deck was designed and fabricated by kansas structural composites russell, kan., u.s.a. and because of its short 23-ft length, it was supported only on four steel pilings support girders weren't required.
this chapter addresses bridge railings that are classified as traffic railing and combination railing, when used with vehicular traffic. see chapter 3, 'pedestrian, bicycle, and ada requirements for bridge railing,' for use of pedestrian and combination railing with non-vehicular traffic.
section 3: loads and load factors 3-3 21 this design criterion typically applies to pier columns and non-redundant through type superstructure elements, such as through trusses or through arches. due to the improbable coincidence of other loads, the analysis may be limited to the impact load and dead loads with a load factor of 1.0.
girder to design section for negative moment has to be calculated first. in general, live load effects can be calculated by modeling the deck as a beam supported on girders, with one or more axles placed side by side.
customised design and flexibility each janson bridging composite bridge can be custom designed and finished. the handrails, the wear surface and the appearance of the bridge can be carried out to your requirements. the span, width, beam height, building height and load bearing capacity can be selected without restrictions.
