The first example is of multi-girder form, the second is of ladder-deck form. Generally, reinforced concrete deck slabs are the most often used type of deck for steel bridges. Shreedhar, Rashmi Kharde Abstract- The simplest form of bridge is the single-span beam or slab which is simply supported at its ends. Author(s) Kromel E. This thesis focuses on the design of reinforced concrete skewed slab highway bridges that are simply supported on discrete bearing pads. Abutment Design. The design concept of link slabs was then examined to form the basis of design for FRP grid link slabs. Performing Organization Name and Address Department of Civil Engineering 7. After you have summed all the expenses, add 10% from above, since the rule is that the final cost of the project is always higher than the original one. And Comparative study of simply supported slab bridge and Integral Slab Bridge are also performed with taking some spans. design and check the stability of piers and abutments v. Approach slab references were removed and added to Article 19. Slabs are constructed to provide flat surfaces, usually horizontal in building floors, roofs, bridges, and other types of structures. Debris accumulation in the joints can restrain deck expansion, causing undesirable forces in the deck and damage to the structure. The deck can be either an integral part of the support-ing member or, with a thinner upper flange, the pre c a s t member can serve as support for a cast-in-place slab. Deck-type bridges refer to those in which the road deck is carried on the top flange or on top of the supporting girders. K Jain” we find the following load positioning gives the severest effect among other combinations. Deck plate girder bridge over S.

In first chapter are presented two options of bridge and one them is selected to next counting. Introduction , Continued • Bridge deck joints should protect the interior edges of concrete decks from vehicle loads, seal the joint openings, and accommodate movements resulting from temperature changes and creep and shrinkage of concrete • Joint failure is a nationwide problem in the United States • Failure is not necessarily caused by the joint. Berkeley Electronic Press Selected Works. These charts were originally developed using BS 5400 and the Highways Agency's Design Manual for Roads and Bridges (DMRB). Then results of a big test series with slabs under wheel loads, straight and haunched beams under monotonic loading, and RC beams under cyclic loads will be discussed. bridges generally have more stringent performance requirements compared to steels used in buildings and many other structural applications.

The standard 4. 5 bridge deck overhang (cantilever slab) and barriers (railings). The design of the link slab is influenced by variables such as span arrangement, bearing type and arrangement, girder end rotation due to live load, and bridge skew. [2] Link slabs are designed to protect the steel reinforcement from corroding by either: using concrete that bends with microcracking, cracks small enough to prevent water from infiltrating to the steel reinforcement; or covering the surface of the deck link slab with waterproofing membrane. 1, Approximate Methods of Analysis of the current edition of the AASHTO LRFD Bridge Design Specifications, with the following exceptions: 1. A bridge is a structure providing passage over an obstacle without closing the way beneath. The bridge deck will have no footpaths. Beam in Bending. Feldmann, R. Even though the problem of seat width at intermediate hinges was. In cases where the traffic lanes are less than 12 feet wide, N. On that basis, a modified geometry of the transition slab and a new detail for the connection between the bridge deck and the transition slab are proposed. Since the design of steel deck floor slabs is primarily based upon the load-carrying characteristics in a one-way direction (parallel to the deck corrugations), the performance tests are performed on one-way slab elements (see Fig. Deck Slab; Precast Girder; Strands; The excel sheet can be used for the following purposes:-Deck Reinforcement Design; Girder Design; Elastomeric Bearing Design; There are diverse types of bridges which contain various types of structures. Six large scale laboratory tests were performed on two bridge deck cantilevers with a span of 2. LENGTH: 3 spans (2 at 18. Bridge Superstructure deals with the behaviour of different types of bridge decks under different systems of loading. The stringers could be steel beams, precast‐prestressedconcrete girders, or other materials. Furthermore, prestressed deck slabs are commonly used in considerably significant bridge deck replacement projects for example the Woodrow Wilson Bridge shown in Figure-12. Study of effect of curbs on solid deck slab bridges using conventional and finite element method. User Note: Refer to Section 1. The PCA computer program pcaSlab can be used to expedite the design of different slab systems. SITE CONSIDERTION AND DESIGN. Bridge Approach Slab Settlement Solutions. bridge deck design - federal highway administration - us. In order to provide designers guidance on the design of full-depth precast slab systems with their full composite strength, the horizontal shear resistance provided at the slab-to-beam interface must be quantified through further investigation. The details may be incorporated into either the District or the Structure Plans. These slabs, which form the transition from a roadway to the bridge deck are susceptible to settlement due to consolidation of underlying natural foundation soils or local loss and settlement of fill materials. 075 ksf Wearing Surface = 30 psf w. Deck slabs in ladder decks span longitudinally between transverse cross-girders and the primary function of these cross-girders is to support the deck slab. SITE CONSIDERTION AND DESIGN. = Manning's coefficient of friction. When designing a steel girder bridge using phased construction with dead load deflections exceeding 2", my state (Nebraska, USA) requires a closure pour. The top of deck slab (including the sidewalk) shall receive a protective coating (silane penetrant sealer).

Without such an assessment, long term decisions by transportation officials cannot be made accurately. And Comparative study of simply supported slab bridge and Integral Slab Bridge are also performed with taking some spans. Both composite deck slabs and form deck slabs can be analyzed and designed for 3 different loading conditions.

The design traffic lanes and the live load within the lanes should be arranged to produce beam. Slabs are classified into 16 types. MODELLING AND METHODOLOGY First structure of simply supported slab is model in FEM software, then this slab is converted into continuous slab and integral slab. As outlined in Article 9. Since in bubble deck (BD) system, the concrete in the middle of deck's cross sections, mainly in the middle of the spans, is removed, the slabs become lighter compared to the traditional slabs. CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): This paper presents an experimental study on the monotonic and fatigue behavior of a link slab designed for a durable concrete bridge deck system.
