Abstract: Despite growing interest in the use of shape memory alloys (SMAs) in civil structures, much is still to be understood about their behavior in real loading environments. This experimental work focuses on characterizing the ...

Abstract: To address the problem of steel corrosion, fiber-reinforced polymer (FRP) bars are often used as reinforcement in concrete structures. However, conventional FRP bars are characterized by linear elastic behavior that limits ...

Abstract: This study numerically examined the seismic performance of a multiple-frame bridge retrofitted with external shape memory alloy (SMA) spirals actively confining the plastic hinges of the bridge piers when subjected to ...

Abstract: This study evaluates the load rating procedure that is currently used in rating timber piles supporting multiple-span simply supported bridges. For simplicity, these piles are often rated under concentric loads and the ...

Abstract: This experimental work focuses on enhancing the lateral cyclic behavior of RC columns by using an innovative active-confinement technique. The thermally triggered recovery stress of prestrained shape memory alloy (SMA) ...

Abstract: This paper investigates a new simulation framework for analyzing structural systems with unconventional complex materials under extreme loading conditions. The new experimental-numerical simulation method, named material ...

Abstract: Strong earthquakes can result in large longitudinal displacements in multiple-frame bridges. This could lead to excessive displacements/openings at the intermediate joints. Bridges with small seat widths are vulnerable to ...

Abstract: Shape memory alloys (SMAs) are known for their superelastic properties, which have been exploited in numerous applications in the biomedical, aerospace, and commercial fields. More recently, these materials have been ...
