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: Some results pertaining to co-dimension two stochastic bifurcations are presented. The normal form associated with non-semi-simple double-zero eigenvalues is considered. The method of stochastic ...

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: In this paper the effect of small parametric and external stochastic perturbations on a two-dimensional system exhibiting Hopf bifurcation is discussed in detail. It is shown that even small ...

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 ...
