Abstract: The seismic design of cap beam-to-column bridge joints improved dramatically after the 1989 Loma Prieta earthquake, during which many bridge joints were significantly damaged. Because of high shear force resulting in ...

Abstract: Experimental investigation and subsequent analytical studies have shown that the external strut force transfer method of design is insufficient for reinforced concrete bridge joints and overly conservative for prestressed ...

Abstract: An outdoor test was conducted on a prefabricated column–pile cap–pile system at a cohesive soil site. The half-scale test unit consisted of a precast bridge column, a precast pile cap, and eight steel piles. The components ...

Abstract: This paper discusses the results of an experimental study conducted on ASTM Grade 420(60) mild steel reinforcement at varying temperatures and strain rates to aid in the design of structures that experience seasonal freezing. ...

Abstract: Use of precast substructure in accelerated bridge construction (ABC) has been gaining popularity due to its advantages over traditional cast-in-place (CIP) construction. When using vertical precast members (e.g., columns ...

Abstract: Ultrahigh performance concrete (UHPC) is an advanced cementitious material which has excellent mechanical and durability properties, making it appropriate for the rehabilitation of concrete structures. This paper investigates ...

Abstract: Since October 2007, the Federal Highway Administration (FHWA) has required the implementation of LRFD methods in all new bridge designs, including pile design. The resistance factors provided nationally for LRFD of driven ...

Abstract: The unique features of the hybrid frame, which include minimum structural damage when subjected to earthquake loading and the recentering capability, are the result of using a combination of mild steel reinforcement and ...

Abstract: In 1963, a geometry-dependent approach to estimate the coefficient of restitution (COR) was proposed for free rocking structures. Since then, this estimation has been reported as being consistently lower than results ...
