Two different panel lengths were selected. Deck panel types A and B were m ( ft) long, whereas deck panel Types C and D were m (10 ft) long.   For a prestressed concrete segmental box girder bridge, both design and load rating (for oversized load permits) are determined by longitudinal and transverse analyses without considering the influence of the barriers. For the transverse analysis, the maximum moment generated from the live load is traditionally calculated from Homberg charts.

An experimental study is proposed in this paper to investigate the effect of insufficient grouting and strand corrosion on flexural behavior of prestressed concrete (PC) beams. First, experimental design is discussed with different insufficient grouting conditions and the strand corrosion in ungrouted duct.

PRESTRESSED PRECAST CONCRETE PANEL WITHOUT STRANO EXTENSIONS ON SOUTH HALF OF BRIDGE. A series of static and dynamic loading tests was conducted on a full-scale bridge specimen.

The north half of the bridge specimen was made with panels having transverse prestressing strands ex­ tending beyond the panel edges, and the south half, with smooth-sided panels.

The punching-shear behavior of bridge decks under fatigue loading, including the effects of arching action, is studied experimentally and analytically. Adjacent precast prestressed concrete box beam bridges have been used for short and medium spans for decades. This type of bridge is preferred due to its high torsional rigidity, vertical.

Precast, prestressed concrete adjacent box girders are regularly considered for short- to medium-span bridges on secondary roads. This corresponds to spans from 20 ft to ft ( m to m. The effect of excessive debonding of prestressed strands can present a marked impact on the shear performance of prestressed concrete girders.

This effect. EFFECT OF TRANSVERSE REINFORCEMENT Transverse reinforcement is used (a) to transfer shear force from the steel beam to the slabs and (b) to provide confinement against concrete splitting. The transverse reinforcement is the most influential parameter to the shear stud capacity for composite beams with precast hollow core slabs.

Corrosion presents a serious problem in severe marine environments, especially for bridges. This paper explores the use of carbon fibre reinforced polymer (CFRP) strands for prestressing precast concrete girders.

Interaction between Longitudinal Shear and Transverse Bending in Prestressed Concrete Box Girders Article in Journal of Bridge Engineering 22(1) August with Reads.

The idea of prestressing concrete was first applied by Eugene Freyssinet, a French structural and civil engineer, in as a method for overcoming concrete’s natural weakness in tension.

Prestressed concrete can now be used to produce beams, floors or bridges with a longer span than is practical with ordinary reinforced concrete. Adjacent precast, prestressed multibeam bridges have often been used for medium- and short-span bridges. However, there have been longitudinal cracking problems in shear keys and overlays commonly seen on some adjacent precast multibeam bridges during their service years.

The fundamental reason for the problem is the poor transverse connection. The effects of prestress levels on the flexural behavior of concrete beams strengthened with near-surface-mounted (NSM) fiber-reinforced polymers (FRPs) were experimentally evaluated.

Eight beams were tested. Failure of the prestressed strengthened beams occurred because of concrete cover separations at one end of the carbon FRP (CFRP) plates. the analysis of transverse prestressing restraint effects in slab-girder bridges assume that a bridge deck basically be-haves compositely as an elastic slab continuous over the supporting girders.

To illustrate Eq. (1), if the design transverse prestress is psi ( MPa) in an 8 in. ( cm) slab, then the transverse slab prestress force per unit. Precast, prestressed concrete adjacent box girders are widely used in short-and medium-span bridges.

Rapid construction and low construction cost are the main attractions of this system. Also, the continuous flat soffit and relatively high span-to-depth ratio make this system aesthetically pleasing.

Scribner, Kazuo Kobayashi Click here to access the full journal article. Abstract. Basic research was done to determine the characteristics of bond for initially untensioned seven-wire strands subjected to repeated and. This paper describes a preliminary investigation on factors related to the use of recycled concrete aggregates (RCA) in precast/prestressed concrete applications.

In particular, the effects of RCA are experimentally investigated for: 1) the bond between seven-wire prestressing steel strand and concrete; 2) the compression strength gain of.Strand debonding is a common procedure used in prestressed concrete members for limitation of compressive and tensile concrete stresses near the element ends, i.e., in the anchorage zone.

The use of high curing temperatures during fabrication affects the level of prestress because the strand length is fixed during the heating, the coefficients of thermal expansion of steel.
