Prestressed concrete for short-span bridges Durable structures built quickly, competitively with standard members BY M. HURD ENGINEERING EDITOR BEFORE AND AFTER: The old bridge on a Pennsylvania farm was replaced with prestressed concrete designed for HS live load and to meet Pennsylvania Department of Transportation standards.

The?id=baf-dbf3-afbff28d   Continuous highway bridges with precast, prestressed girders have been built by a number of states. Examples of bridges of this type built by the states of Tennessee and California are presented in Figs.

Short-span bridges, having span lengths from 25 to 60 ft ( to m), account for half the publicly owned structures in New York State, which suggests the potential benefits for the State Department of Transportation and others from further economies in construction of bridges in this span ://   1 Types of reinforced concrete bridges.

The type of reinforced or prestressed concrete bridge deck depends mainly on the functional requirements, the structural form, and the main span length of the construction.

Precast or cast in situ reinforced concrete (r.c.) bridge decks can be practically applied for all structural types, like arch, cable Concrete is a leading contender for replacement or new construction of the short or short span bridges because of its adaptability, durability, low maintenance, and low life-cycle cost.

Whether bridges are cast in place or precast and prestressed--or a combination of the two--will depend on site conditions as well as local economic and /economical-short-span-concrete-bridges_o. The parametric design study indicated that for bridges spanning from – ft, continuous precast, prestressed concrete girder bridges with in-span splices can provide an economical alternative to steel girder bridges and segmental concrete box girder construction.

The tested splice connections performed well under service level ://, Home / Precast Products / Bridges Whether you want to replace a deficient structure, span a roadway or water, or create a tunnel, precast concrete bridge components provide the perfect solution. Designs include attractive single-piece arches, functional two-piece arches, conventionally reinforced flat bridges, parapets, wingwalls, headwalls and   solution in the short and medium span range.

Decisive for the success of these developments is the current low price of structural steel and the high rate of prefabrication concerning steel construction as well as precast concrete members.

EVOLUTION OF PROPOSED SYSTEM A survey8 concerning the develop­ ment of a new precast, prestressed sys­ tem for short to medium span bridges up to ft ( m) was sent to Journal//Jan-Feb/Precast Pretensioned.

However, Colorado’s standard precast concrete bulb-T shapes were too deep for the site, and steel was eventuallychosen. The designers applied solutions generally reserved for precast concrete to this material alternative.

Uses of Prestressed Concrete There are a huge number of uses: • Railway Sleepers; • Communications poles; • Pre-tensioned precast “hollowcore” slabs; • Pre-tensioned Precast Double T units - for very long spans (e.g., 16 m span for car parks); • Pre-tensioned precast inverted T beam for short-span bridges; Precast Prestressed Concrete Short Span Bridges: Spans to Feet 2nd Edition ISBN ISBN Why is ISBN important.

Precast prestressed concrete double-T beams for short-span bridges. [Osman Hag-Elsafi; New York (State). Transportation Research and Development Bureau.] Conventional slab beam bridges have precast concrete slab beams placed immediately adjacent to one another with a cast-in-place topping slab.

While this bridge system is commonly used for short-span bridges due to its shallow profile, it is more expensive than typical prestressed I-beam ://   procedures for long-span prestressed concrete bridges of segmental construc­ tion. This report presents a critical summary of the present "state of the art" for such structures.

In preparation of this report, all available pub­ lished engineering articles on the subject were reviewed, and a number of. Precast prestressed concrete can be a strong, durable, and aesthetically pleasing material for use in long‐span bridges. If erected using the proper techniques and care, such bridges meet society's demands very well.

Specifically, prestressed concrete allows for stronger bridges at lower construction and maintenance ://(ASCE)()(95). Both pretensioning and post-tensioning are included as well as precast and in situ construction.

Recent developments in the use of non-metallic materials to improve the durability of prestressing systems and higher strength concrete are included to show how prestressed concrete bridges are likely to develop in the ://  Standard AASHTO-PCI, Type BIV, Prestressed Concrete Box Beam for Highway Bridges of ft Span Length (Conversion: mm = in.
