Deck slab design example 4) 4-Design of Slab Bridge (AASHTO) The slab bridge is short-span Bridge consisting of a reinforced-concrete Slab resting on piers or abutments (supports). This leads to simple loading conditions and the slab can be designed in a similar way to The design of composite slab is carried out based on empirical design formula, available test data and using IS 11384 (1985) and Eurocode 4 (2004). 1. The beams are ASTM A992 and are unshored. Project Name: A - NWC Slab & Girder, φ = 0. The amount of reinforcement in the secondary direction in the top of the deck slab depends on whether the deck slab is in an area in which the main supporting girders are subjected to negative or positive flexure. Main reinforcement may be designed by use of the tables on File No. 1-5 Example of a Steel Girder Bridge 2 Design Guide for Concentrated Loads on Metal Deck Slabs; Design Guide for Controlled Rocking Steel Braced Frames; Design Guide for Steel Framed Carparks; Architecturally Exposed Structural Steel; Steel Advisor; Design Example – Column in Simple Construction February 15, 2012 . 15 meter clear span. According to CA 9. Splices in the top primary reinforcement in the cast-in-place portion of the deck slab are not to be located at the panel joints. The material in the slab is homogeneous and isotropic; the slab and girders behave in a linearly elastic manner; 2. ” For example, the ultimate uniform design load, Wu, is wu ( 2) where w1 Weight of slab (steel deck plus concrete dead load), psf w3 Dead load applied to slab, exclusive of LL Allowable superimposed live load for service conditions, psf w1 beginner education. 4 The FHWA link-slab design example is a valuable resource to bridge owners and bridge designers looking Comprehensive Design Example for Prestressed Concrete (PSC) Girder Superstructure Bridge Design Step 7 Design of Substructure Design Step 7.

For a 250mm deck slab this leads to a maximum span for the slab of about 4m. The provisions in this article are meant for slab-type bridges and their purpose is to limit deflections under live loads. The design principles of a solid slab bridge deck may be illustrated by the following illustrative example: Illustrative Example 1: Design a solid slab bridge superstructure having a clear span of 9. View example in PDF format Design of Deck Slab: ADVERTISEMENTS: Since the deck slab is monolithic with the cross-beams, it will be designed as a two-way slab supported on longitudinal girders and cross-beams with continuity on all sides. Additional details on previously constructed link slabs and the approaches used by several states for the design and implementation of link slabs are summarized by Thorkildsen3 and Ailaney. 500 12. The first example is of multi-girder form, the second is of ladder-deck form. The conventional floor slab has few drawbacks of giving little structural support and posing a large amount of self-weight to a building. It outlines the design process, which includes: 1) Selecting a deck thickness of 250 mm based on AASHTO requirements. Here plastic analysis of composite section under factor load is also considered. Normal Slab bridges Solid slab decks comprise a solid section, without beams or voids. 4 developed by Alex Tomanovich.

"DECKSLAB" is a spreadsheet program written in MS-Excel for the purpose of analysis and design of slabs on metal deck. Total design bending moment for Dead Load and Live Load= Four long span composite slab specimens of 20 ft span length, using two different types of deck profiles, were built and tested experimentally. Stiemer Appendix A Note: Examples as presented may be according CSA S16. 4B. - The slab thickness is designed to be 500mm thick. 01 Design Loads Section 2: SUPERSTRUCTURE DESIGN 1. It includes bridge geometry, material properties, design load calculations for dead and live loads, and reinforcement details for the deck slab and kerb beam. deck and joists. (AASHTO LRFD 9. It analyzes the deck slab transversely as a continuous slab supported by longitudinal girders, accounting for loads such as dead load, superimposed dead load, and live loads. 03 Edge Beam Design Loads 2. SDI C-2017 Section 2. 225 0. 3) Computing dead loads from the slab, future wearing surface, and EX. This design guide provides a basic procedural outline for the design of slab bridges using the LRFD Code Example I-1 Composite Beam Design Given: A series of 45-ft. CONCRETE OVER METAL DECK is a very common construction method for elevated slabs for a wide range of building types, including steel-framed commercial and industrial buildings. 00 Bridge Cross Section Stress Limits at Transfer Overall Deck Width: 51. Loading: Single lane of IRC Class 70-R One Way Deck Slab Design Excel Sheet. See the current Staff Bridge Design Memo 601 for descriptions of effective span and general deck slab design information. Materials and their Promises (Figure 4) developed by Caner and Zia [2] for link slab design. Applying these provisions to the design of deck slabs rarely controls deck slab design. net DESIGN OF COMPOSITE DECK SLAB Kamal B 1, Alamelu G 2, Abinaya D 3 ü Composite Deck Design Examples – Shortcuts for Multiple Loads ü Form Deck and Steel Fibers 6 Deck Types Roof Deck • Permanent Structural Member • No Concrete Topping Two way slab design? This sounds complicated, but the next few graphs and example problem makes understanding and analysis relatively easy. This involves calculating live load effects on a transverse deck PDF | BubbleDeck is the invention of Jorgen Bruenig, who devised the first biaxial hollow slab (now known as BubbleDeck) in Denmark. pdf Content uploaded by The deck slab bridge comprises superstructure as deck slab and supports as abutments. 02 Flat Slab Design 2. 200 ksi Number of Beams: 6 Tension (w/ bonded reinf): -0. Beam and slab bridges are the most common form of concrete bridge in today. m. 3. 00 ft Deck Slab Thickness: 8. 121. The slab is to be constructed using profiled metal decking and normal weight, grade 30 concrete. FOREWORD In 2021, ultra-high performance concrete (UHPC) for bridge preservation and repair was rolled UHPC link slab bridge deck joint and support pier, existing section. But, until further durability testing of this design method is completed, the empirical design method is not permitted for concrete bridge deck design in California (CA Article 9. Starting in STAAD. 5 metres wide footway on either side for a National Highway. As the slabs are solid, the cross-section from any point is a homogeneous structure. 4) (. Tips for more efficiently determining point loads for composite elevated deck slabs. Short Term Losses 1. Design Step 4. 1 - Obtain Design Criteria Design Step 2. 5 ksi Concrete elastic modulus (calculated using S5. CRITERIA . reinf. For this example, the approximate method is used. For the cast-in-place slab placed above the precast deck panel, Article 9. It includes calculations of load intensities from bogie axles, required and provided reinforcement at the top and bottom, design of shear connectors, and connection of shear connectors to the top flange. The primary aim of this particular example is to show the LUSAS model building requirements to allow a design check with PontiEC4 to be carried out. Materials and design parameters are provided. The designing by the software saves the design time and by this way we can check the safety of the structure very easily. 3. Empirical Design (AASHTO Article 9. 8 meters for edge strips. Analysis of Slab Decks: The analysis of deck slabs can be done in two ways depending upon the importance and classification of bridge They are Solid slabs spanning in one directionSlabs spanning in Two directions The center of According to our project we are using slabs Chinese Design Examples EX. Concentrated Load Wall Load Parallel to Deck Span This video includes design of Bridge Deck slab to support IRC class AA loading (Tracked Vehicle). The thickness of a floor slab must be determined early in design because the weight of the slab is an important part of the dead load of the structure. 03 Bent 2 Piles Vertical Load Design 3. Part two provides typical practice for design including transverse and longitudinal design along with design examples. The examples cover the principal steps in the verification of the Prestressed Precast Concrete Beam Bridge Design. Since then, | Find, read and cite all the research you need AASHTO LRFD Bridge Slab Design Calculator Spreadsheet. This design should always be used unless approval to use a thinner deck is obtained from the State Bridge Engineer. 0 • Composite and Non-Composite Design Guide www.
