The Penobscot Narrow Bridge, Maine’s first cable-stayed bridge, was constructed between May and December (Fig. 7). The bridge, with twin pylons and a ft ( m) span, uses an innovative cradle system to carry the stays from the bridge deck through a pylon and back to the bridge deck. In each pylon, 20 stays run.

Application of transverse prestressing for bridge decks book This paper summarizes a series of interrelated physical tests and computer analyses which were conducted to provide necessary information for the development of design criteria for transverse prestressing of bridge by: 6.
Previous research and utilization of transverse prestressed elements was reviewed for the purpose of developing a state-of-the-art report on the concept of transverse prestressing of bridge decks. This material served as the basis for panel discussions among senior engineers to develop new and innovative concepts for design of prestressed decks.
The project's aim is to investigate the potential for improving the serviceability and economy of bridge decks through use of transverse prestressing. Corporate Authors: Engineers' Society of Western Pennsylvania.

The deck slab of a prestressed concrete (PSC) box girder bridge serves as an integral part of the structural box section, and any damage to the deck may seriously affect the load-resistance mechanism of the bridge. Transverse Analysis of a Prestressed Concrete Wide Box Girder with Stiffened Ribs concrete box girder with transverse ribs is already used in certain countries to meet the requirements of wide bridge decks of single-cell concrete box girders.
However, little research has been conducted on the mechanical properties of this spine-like box. prestressed concrete bridge deck panels.
These guidelines are based on the latest research and practical experience gained from their use in various parts of the United States. After a brief review of the history of bridge deck panels, suggestions are given for the dimensioning and detailing of panels, techniques for casting.
The entire bridge deck, including the swing bridge, is made of prestressed concrete. The main bridge was built by incremental launching, with a unit length of m corresponding to 1/3 of the regular span.
With respect to this construction procedure, its depth is m, corresponding to 1/ of the regular span. The swing bridge. An Investigation on Transversely Prestressed Concrete Bridge Decks 5. Report Date December 6.
Performing Organization Code 7. Author(s) application of deck edge transverse post. Composite bridge decks under concentrated wheel loading develop compressive membrane action that tends to increase significantly the strength of the deck slab.
Transverse prestressing of the deck slab can improve the compressive membrane action and allow a. Transverse post-tensioning can be determined as a function of bridge geometry such that deck cracking due to temperature changes and traffic loads is mitigated.
The recommended transverse post-tensioning system is defined by the number of diaphragms and the force applied at each diaphragm. Transverse post-tensioning. Figure 8 - Minnesota’s first major prestressed-concrete bridge, Bridgecarrying 94th Street over Interstate 35W in Bloomington, Minnesota.

The basis for calculating the transverse post-tensioning force according to PCI’s Precast Prestressed Concrete Bridge Design Manual is discussed. composite deck, and transverse. BRIDGE DECKS September DESIGN DETAILS FOR BRIDGE DECKS General The following general criteria apply to bridge decks that are constructed compositely in conjunction with concrete girders, steel girders and the top slabs of cast-in-place, post-tensioned box girders: 1.
Thickness. Each box-beam bridge model consisted of 2 precast prestressed box beams placed adjacent to each other and a CFRP/CFCC reinforced deck slab. The 2 box beams of each bridge model were prestressed using 7 pretensioning tendons/strands and consisted of 4 transverse diaphragms for transverse post-tensioning.
1) Identify ways of controlling cracking in precast, prestressed bridge deck panels; and 2) Optimize reinforcement in the cast-in-place concrete placed on bridge decks.

Almustafa, R., "The Analysis of Transverse Prestressing Effects in Bridge Decks," PhD Dissertation, The University of Texas at Austin, December 7.Transverse post-tensioning is done to strengthen the deck slab (or sometimes diaphragm) in direction perpendicular to traffic flow.
It's purpose is similar to longitudinal post-tensioning, only the direction of application is different. It is usua. 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-stayed, extradosed, and even suspension.
