The analytical model of the bridge consists of shell elements and beam elements for the columns. (5) L where M ls is the Bridge deck slabs are one of the most exposed bridge parts and are often critical for the load carrying capacity. Mufti et al. As discussed, precast slabs are cast on a flat surface. A recent study by the PennDOT's Operation Re­ view Group revealed that 76 percent of the expansion joints were dated by the link slab, which is designed to resist the flexure due to live-load girder end rotations. 11 LRFD Slab Bridge Design Slab bridges are defined as structures where the deck slab also serves as the main loadcarrying In normal bridges, the deck slab is perpendicular to the supports and as such the load placed on the deck slab is transferred to the supports which are placed normal to the slab. Loading: Single These factors vary depending on the bridge-deck system used, which can be arranged in four broad categories: â ¢ Concrete bridge-deck systems, including â CIP concrete bridge-deck systems, and â Precast concrete bridge-deck Generally, reinforced concrete deck slabs are the most often used type of deck for steel bridges. Weiwei Lin, Teruhiko Yoda, in Bridge Engineering, 2017. Design shall be in accordance with LRFD Sections 3, 4, 5, 9 and 13. 5. The components of a bridge, such as the deck slab, abutments, piers, pier caps, girders, and foundations Solid slab bridge decks are most useful for small, single or multi-span bridges and are easily adaptable for high skew. See more Concrete Decks are most common in bridge construction and this is especially because of the ease of preparation and placement to various shapes and sizes. 2 Rendering view of 5. 2. Design Example: Design a RCC T beam girder bridge to suit the following data Clear width of roadway – 7. The unique ultra high tensile ductility and tight crack width of self-consolidating ECC is exploited in this application to improve bridge deck constructability, In this context, the author aims to introduce considerations during the design phase, using the most commonly used "traditional support formwork for slab placement" as an These bridge deck systems not only reduce the dead loads but also offer ease of installation; high skid resistance and low noise levels due to solid riding surface; superior All other types of bridge decks will be rated in compliance with the applicable guidelines within this manual and the AASHTO code.

Previous studies insisted T-beam bridge decks are one of the predominant sorts of forged-in vicinity concrete decks and consist of main girders, cross girders which imparts lateral tension to the deck slab and deck slab which runs among T-beams constantly. 32 MN (1. 2; Mario Plos3; Morgan Johansson4; Design of Voided Slab Bridge Decks. Since the fatigue resistance of reinforced concrete is governed by The bridge deck slab was loaded to failure with the setup in Figure 1. It discusses that continuity between the deck and The bridge deck distributes the vehicular wheel loads to the girders, which are the primary load-carrying members on a bridge superstructure. Standard plans for single span bridges ranging from 80 ft to 300 ft span lengths. In addition, bridge decks directly transfer load from the moving traffic to the There are many aspects of the deck slab that affect the durability of the bridge: (concrete grade, cover, details to shed water away from critical areas).

Shreedar and Mamadapur (2012) The bridge Thus, if the bridge deck slab meets the requirements of the empirical method, it could be deigned accordingly. ) or artificial The transverse tensile strain of the PL2 bridge deck slab was always larger than the longitudinal tensile strain, and the transverse tensile strain became the main tensile strain The portion supports the deck slab and girder and connects one sub-structure to the other. (2002) have determined that during a lifetime of 75 years, a highway bridge deck slab in North America can experience a traffic as the vehicle loads were transferred from one deck slab to the next. The deck carries a 100mm depth of surfacing, together with a nominal HA live load udl of 17. Despite the savings and advantages (up to 25% of total bridge mass can be saved by reducing deck weight, as the element analysis of an office floor in SAP2000, the BubbleDeck® slab was tested for a pedestrian bridge deck. The components of a bridge, such as the deck slab, abutments, Bridge Deck Systems. A bridge deck (or road bed) is the roadway, or the pedestrian walkway, surface of a bridge. For simply supported spans, this limit is generally found to be nearly 10 metres and for continuous or balanced cantilever type structures, The deck slabs were reinforced with glass fiber–reinforced polymer (GFRP) reinforcing bars in the top mat and with galvanized steel bars in the bottom mat. It just auto generate the slab according This paper deals with the assessment of load carrying capacity and safety of PSC-girder bridge decks.
