many of the precast bulb-T (PCBT) beams used in the Commonwealth of Virginia develop cracks within the anchorage zone region. The lengths and widths of these cracks range from acceptable to poor and in need of repair. A diagram of a typical crack pattern in a PCBT anchorage zone is shown in Figure 1.

Bulb-Tees SHERRELL HELM Standard AASHO precast, prestressed concrete beams are widely used throughout the United States. The standard sections were developed in the 1950s taking into account the casting and han dling techniques and the concrete mix design technology of the 1950s.

DESIGN RECOMMENDATIONS FOR THE OPTIMIZED A bridge comprising simple-span precast, prestressed bulb-T beams made continuous with a cast-in-place diaphragm and composite with a cast-in-place deck is a very efficient and durable system. In 2005, Newhouse presented a detail for the positive moment connection for
Decked Bulb Tees Decked bulb tee girders are a versatile long span girder that incorporates the benefits of both an I girder, and a precast slab deck. These girders are typically used for vehicle bridges and can range in length from as small as 40 up to 160. Many of the benefits of these girders come from the versatility of the deck.

Flexural Behavior of CFRP Precast Prestressed Decked Bulb The new bridge superstructure is assembled from precast prestressed decked bulb T-beams reinforced and prestressed with corrosion-free fiber-reinforced polymer (FRP) materials. An experimental investigation accompanied by analytical and numerical sim- ulations was developed to evaluate the performance of the newly developed beams.
Northeast Prestressed Products, LLC and its predecessor have worked hard since 1950 to become your single source for the highest quality prestressed/precast concrete bridge components; including I-Beams, Bulb Tees, Adjacent & Spread Box Beams as well as bridge items not traditionally specified as prestressed/ precast concrete.
Prefabricated Bridge Elements and Systems for Bridge Prestressed Bulb Tee AASHTO girders are modified which is more economical for spans of larger than 24 m. the beams possess large section modulus to weight ratio and beams with span of larger than 54 m have been produced. a prestressed bulb tee is illustrated in Figure-8.

precast material, precast material Suppliers and A wide variety of precast material options are available to you, such as 100% polyester, 100% polypropylene. You can also choose from anti-static precast material, as well as from ce precast material There are 12,522 suppliers who sells precast material on , mainly located in Asia.
Precast girders are corrosion and deterioration resistant, use less seams than traditional methods, and ensure quality through structural consistency. For projects requiring heavy loads or long spans, Oldcaslte Infrastructure prestressed, post-tensioned girders provide
