Abstract: Potential plastic hinge zones in confined concrete columns require that sufficient transverse reinforcement be provided to avert undesirable failure modes and to ensure dependable inelastic (ductile) behavior in earthquakes. ...

Abstract: ASTM A615 grade 40 ordinary deformed‐steel reinforcing bars with a specified minimum yield strength of 276 MPa (40 ksi) and ASTM A722 high‐strength prestressing thread bars with a specified ultimate strength of 1,083 MPa ...

Abstract: A stress‐strain model is developed for concrete subjected to uniaxial compressive loading and confined by transverse reinforcement. The concrete section may contain any general type of confining steel: either spiral or ...

Abstract: Thirty‐one nearly full‐size reinforced concrete columns, of circular, square, or rectangular wall cross section, and containing various arrangements of reinforcement, were loaded concentrically with axial compressive strain ...

Abstract: Circular reinforced concrete highway bridge piers, designed in accordance with the requirements of the California Department of Transportation (Caltrans) in the U.S., New Zealand, and Japanese specifications, are experimentally ...

Abstract: Recent earthquakes such as Loma Prieta, Northridge, and Kobe have demonstrated a need for a new design philosophy of bridge piers that avoids damage in order to ensure postearthquake serviceability and reduce financial loss.

Abstract: An analytical macromodel based on an equivalent strut approach integrated with a smooth hysteretic model is proposed for representing masonry infill panels in nonlinear analysis of frame structures. The hysteresis model ...

Abstract: To investigate the seismic behavior of bridge pile-to-pile-cap connections, five full-scale H-shaped steel pile-to-pile-cap connection subassemblies representing a portion of a typical bridge pile foundation were tested. ...
