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: A method for obtaining the Kostiakov equation parameters for the different U.S. Soil Conservation Service (SCS) infiltration families is given along with the results. The deviation functional integrated over period of time ...

Abstract: The precast wall with end columns, known as the PreWEC, was developed as a solution for resisting earthquake lateral loads and validated using quasistatic testing. This paper presents a shake table investigation of this ...

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: The strength and ductility of concrete can be improved by adding confinement, which helps RC structures to withstand extreme loads in a ductile manner. However, the confined concrete behavior in hollow sections is not well ...

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 ...
