Rehabilitation of Longitudinal Joints in Double-Tee Girder Bridges
… Among several bridge girder types, precast double-tee girders are common on county bridges in South Dakota because of the ease of construction, the reduced construction time, and the potentially lower overall cost. However, the longitudinal joints of these bridges are rapidly deteriorating …

The Development of a Steel Embedded Connection for Double-Tee Beams
… Pittsfield, Massachusetts. JVI has developed a steel embedded connection, referred to as a shooter. The shooter is provided in capacities, a 40 kip capacity shooter and a 50 kip capacity shooter. This steel connection is embedded near the end of a double-tee prestressed girder. Double-tee …

Glulam Timber Bridges for Local Roads
… Dakota (SD) local roads are prestressed precast double-tee bridges. Currently, there is only one double-tee girder manufacturer in South Dakota (SD). In an attempt to provide more bridge type selection options for local governments, a study was performed at South Dakota State University to …

Precast Full-Depth Deck Panels Supported on Inverted Bulb-Tee Bridge Girders
… of Transportation (SDDOT) currently uses precast double-tee bridge deck systems for many of its county bridges because they are economical and fast in construction. Current bridges are designed for a service life of 75 years. However, many double-tee girder bridges are deteriorating and some need …

Fundamental frequencies of I-joist, solid-sawn wood joist, and truss floors based on tee-beam modeling
… were built and their frequencies were measured. Double tee-beam floors were built and also cut from the full size floors and their frequencies were measured. The floor joists investigated included: solid sawn, parallel chord floor trusses, and composite I -joists. The first natural frequency of …

Immediate Deflection Calculations Of Transition And Cracked Prestressed Concrete Sections
… bridge members. In prestressed concrete, the steel strands are tensioned/pulled and then concrete is cast around the strands in the form. Once the concrete has set, the strands are cut, and the member is put into compression from the pre-tensioned strands. Concrete is classified as uncracked, …

Elastic-Damaging Plasticity Model for Ductile Fracture
… can characterize ductile fracture in ferritic steels and that can be used in practical engineering problems. Ductile fracture occurs by a sequential process of nucleation, growth and coalescence of microvoids or microcracks. However, the model uses a continuum approach that can capture the …

Model-based optimization of ultra high performance concrete highway bridge girders
… Design solutions are proposed for prestressed double-tee sections for small and medium span highway bridge girders (21.3 - 36.6 m (70 - 120 ft)), which possess many advantages over conventional precast concrete solutions (reduction in height and weight, elimination of shear reinforcement, …

Development and Behaviour of a New Long-Span Composite Floor System
… the floor looks like a nine-metre-long double-Tee floor with hanger systems at its supports, but with unusually thin ribs. Internally, a new load-carrying system has been developed, using a centrally placed perforated light-gauge steel sheet. By providing a continuous medium for internal …
