Abstract: This paper presents an analytical investigation of the nonlinear behavior of precast concrete coupling beams under monotonic lateral loading. In contrast to conventional monolithic concrete coupling beams, coupling of ...

Abstract: This paper describes the results from eight half-scale experiments of unbonded posttensioned precast concrete coupling beams under reversed-cyclic lateral loading. Each test specimen includes a coupling beam and the adjacent ...

Abstract: This paper provides an experimental validation on the analytical modeling and design of unbonded posttensioned precast concrete coupling beams. Previous test results from a series of floor-level coupling beam subassembly ...

Abstract: In New Mexico, bridges without plans are currently an issue as in other states in the US. Standard techniques cannot be used for load rating due to the lack of design plans that contain necessary information such as material ...

Abstract: This paper uses the experimental results presented in a companion paper to develop a seismic design approach for unbonded posttensioned hybrid coupled wall subassemblages. The test results are also used to verify and refine ...

Abstract: Eleven half-scale experiments were conducted to investigate the nonlinear reversed cyclic behavior of coupling beam subassemblages in a new type of hybrid coupled wall system for seismic regions. In this new system, coupling ...

Abstract: This paper presents the experimental investigations and analytical modeling of the strength and flexural characteristics of a locally (Las Cruces, New Mexico) developed fiber-reinforced ultrahigh-performance concrete (UHPC). ...

Abstract: Acoustic emission (AE) data were investigated to better understand damage conditions in a three-span prestressed concrete girder bridge during a load test. The innovation lies in classification of crack extensions (stable ...

Abstract: Ultrahigh-performance concrete (UHPC) exhibits exceptional strength and durability properties that facilitate smaller, more efficient members that have longer expected lifespans compared to conventional concrete. However, ...
