This document provides guidance on designing slab bridges using Load and Resistance Factor Design (LRFD). SCI design guides have generally adopted deck and joists. It discusses two methods for deck design allowed by the AASHTO LRFD specifications: the approximate equivalent strip method and the empirical design method. In the example, Class 70-R tracked vehicle will govern the design. Full composite action occurs between the slab and ec­ centric girders; 3. The deck carries a 100mm depth of surfacing, together with a traffic load (LM1) udl of 5. 3. 1. Develop influence line diagrams and determine maximum shear and moment. This spacing is consistent with the maximum span of permanent formwork, typically about 3. Slab bridges are defined as structures where the deck slab also serves as the main load-carrying component. A RCC deck slab is to be constructed over a channel on a national highway for Class AA tracked vehicles. Decking not only serves as a permanent formwork for concrete, RSTAB 9 is a powerful analysis and design software for 3D beam, frame, or truss structure calculations, reflecting the current state of the art and helping structural engineers meet requirements in modern civil engineering. The design for the slab is checked firstly for bending capacity assuming full bond between concrete The designer needs to consider required deck thickness. the Mid Span: For this example, a slab thickness of 8 in.

The material in the slab is homogeneous and isotropic; the slab and girders behave in a linearly elastic manner; 2. Girder spacing is controlled by the spanning ability of the concrete deck slab. Materials and design parameters are provided. View. 3 & R8. 1 Introduction: For short spans, a solid reinforced concrete slab, generally cast in-situ rather than precast, is the simplest design. Preliminary Slab Design Before making a decision regarding which floor framing alternative to adopt, it is necessary to establish the maximum decking span corresponding to the spacing of the secondary beams. The Applying these provisions to the design of deck slabs rarely controls deck slab design. The design provisions are Based on the concrete deck design example, the total area of longitudinal deck reinforcing steel in the negative moment region is computed as follows: Slab Haunch. 40 2 Loads “Adjacent”, M w b e Download CAD block in XLS.

Short Term Losses 1. 1 - DECK DESIGN GENERAL INFORMATION Based on AASHTO LRFD Bridge Design Specifications 9. 1 shows the typical sections of the solid deck Slab Bridge which contains components such as deck slab wearing coat, abutment and footing. 3, meaning Clause 6. Depending on the span length and the amount of prestress ing, the slabs will deflect upward. Use f c’=30MPa and f y =400 MPa. STANDARD DIMENSION OF DECK SLABS Based on the Standard Drawings of MORT & H (1991), dimensions of deck slabs are taken as follows: Span (m) Avg. This document provides a design example for a reinforced concrete slab bridge. 8m. SDI C-2017 Section 2. It includes summaries of the superstructure design process, which involves deck design using the standard NMDOT detail, girder analysis and design using CONSPAN software, and bearing pad design. ” SAMPLE SLAB DESIGN DETAILS - Free download as PDF File (. Four long span composite slab specimens of 20 ft span length, using two different types of deck profiles, were built and tested experimentally. 750 RCC T-BEAM 3. This document provides a design example for a three-span prestressed concrete girder bridge with a 50 ft wide roadway. The designing by the software saves the design time and by this way we can check the safety of the structure very easily. McCabe1 The enclosed example is presented to demonstrate the intent and use of the AISI "Tentative To make the slab design independent of the type of rail, we will place the wheel load 1' from the nominal face of the rail (1ft from the edge of the slab). 1 (Caltrans 2008a), the minimum deck thickness is to “conform to the deck design standards developed by Caltrans”. 500 1. 4) (. reinf. 500 0. Shoring will not be used. 1. (2017) design code. Composite Joists And Deck Create Spans Up To 60 Feet. com Non-composite deck 6 inch depth, 12 inch coverage 14 foot to 25 foot Span Range No Acustadek® Option Allows for longest unshored spans For use when metal deck is used as a leave in place form Design Step 4 – Design of Deck Prestressed Concrete Bridge Design Example Task Order DTFH61-02-T-63032 4-3 For this example, a slab thickness of 8 in.
