Abstract: Superelastic (SE) shape memory alloy (SMA) is an advanced material that may be used as an alternative to conventional reinforcing steel in civil engineering structures to control residual deformations. The most common SE ...

Abstract: A method to utilize fiber composites for rapid repair of earthquake damaged flared columns was developed. Two 0.4-scale reinforced concrete columns that had been tested to failure in previous research were used. Both columns ...

Abstract: Accurate prediction of instantaneous and time-dependent deformation of superstructure in-span hinges is important for preventing a mismatch of bridge decks. Time-dependent deflection of in-span hinges hinge curl in ...

Abstract: Prefabrication of structural elements is the integral part of accelerated bridge construction (ABC). Providing constructible beam-column and column-foundation connections that can tolerate inelastic cyclic deformations is ...

Abstract: The main objective of this study was to develop a rapid and effective repair method using carbon fiber–reinforced polymer (CFRP) fabrics for earthquake-damaged circular RC bridge columns based on apparent damage states. A ...

Abstract: This paper presents the results of an experimental and analytical evaluation of one-way reinforced-concrete pier hinges subjected to a combination of axial compression, shear, and moment in the strong direction. Thirty-four ...

Abstract: Different types of connections have been used in practice to simulate a hinge behavior at the base of bridge columns. Previous earthquakes demonstrated that none of them could remain elastic and damage free during the ...

Abstract: Three unconventional details for the plastic hinge regions of bridge columns subjected to seismic loads were developed, designed, and implemented in a large-scale, four-span RC bridge. Superelastic shape memory alloys ...

Abstract: This paper presents a simple model to calculate concrete properties for reinforced concrete members that are confined by carbon-fiber-reinforced plastic (CFRP) sheets. The model simplifies and incorporates formulas from ...
