Abstract: A model for predicting punching shear failures at interior slab-column connections was developed based on experimental results obtained at various universities. This model has been incorporated into a new RC slab element ...

Abstract: The design and construction of spread slab beam bridges is becoming commonplace in Texas. Although this relatively new class of bridge is somewhat similar to spread box beam bridges, it is unclear whether the existing live ...

Abstract: This paper documents an experimental testing program on the lateral in-plane behavior of pre-1950s existing and rehabilitated wood floor and roof diaphragms in unreinforced masonry buildings found in the Central and Eastern ...

Abstract: This paper provides an approach to conduct a probabilistic assessment of structural damage due to seismic events with an application to typical building structures in mid-America. The developed methodology includes modified ...

Abstract: The Texas Department of Transportation (TxDOT) uses precast prestressed concrete slab beams in a side-by-side configuration for short-span bridges in low-clearance areas. To reduce costs, a new bridge type called a spread ...

Abstract: The presence of air voids, moisture, and chlorides inside tendon systems on segmental posttensioned (PT) bridges has been cited as a reason for the early age corrosion and failure of strands in these bridges. This paper ...

Abstract: Concrete design codes include equations to estimate the modulus of rupture (MOR), modulus of elasticity (MOE), and splitting tensile strength (STS) of concrete based on the compressive strength. These equations have been ...

Abstract: The steel strands in posttensioned (PT) concrete systems are typically embedded inside cementitious grout for protection from the environment. However, strands not embedded in grout have been observed in PT systems. The ...

Abstract: Posttensioned (PT) bridges are used on major thoroughfares because they are economical structures for traversing long spans. Special inspections of these bridges have revealed corrosion of the strands at void locations in ...
