RISImpact of Code Requirements in the Central United States: Seismic Performance Assessment of a Reinforced Concrete Building
Publisher: American Society of Civil Engineers
Abstract: The close proximity to the New Madrid Seismic Zone and the significant population and infrastructure presents a need to evaluate the seismic provisions in building codes adopted in Memphis, Tenn., and other central U.S. ...
Nonlinear Punching Shear Failure Model for Interior Slab-Column Connections
Publisher: American Society of Civil Engineers
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 ...
Live Load Distribution Factors for Spread Slab Beam Bridges
Publisher: American Society of Civil Engineers
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 ...
Seismic Behavior of Wood Diaphragms in Pre-1950s Unreinforced Masonry Buildings
Publisher: American Society of Civil Engineers
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 ...
Flexural Behavior of High-Early-Strength Self-Consolidating Concrete Pretensioned Bridge Girders: Experimental Evaluation
Publisher: American Society of Civil Engineers
Abstract: A research program investigated the application of high-early-strength self-consolidating concrete (SCC) for precast, prestressed bridge girders. The SCC and conventional concrete (CC) in mixtures had a target 16-h release ...
Probabilistic Assessment of Structural Damage due to Earthquakes for Buildings in Mid-America
Publisher: American Society of Civil Engineers
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 ...
Design and Constructability of Spread Slab-Beam Bridges
Publisher: American Society of Civil Engineers
Experimental Investigation of a Full-Scale Spread Slab Beam Bridge
Publisher: American Society of Civil Engineers
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 ...
Probabilistic Models for the Tensile Strength of Corroding Strands in Posttensioned Segmental Concrete Bridges
Publisher: American Society of Civil Engineers
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 ...
Mechanical Property Prediction for High Early Strength Self-Consolidating Concrete
Publisher: American Society of Civil Engineers
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 ...
