Evaluation of Flexural Behavior of Hollow Prestressed Concrete Pile for Continuous Pile Wall

Ductility Evaluation of Prestressed Concrete Members

In this paper, moment-curvature behavior and ductility of prestressed concrete members based on nonlinear analysis is investigated. Influence of various design parameters on ductility of flexural members is determined according to appropriate materials models for stress-strain curves of concrete, prestressing steel and conventional reinforcements. Parameters studied include reinforcing index (ω...

Evaluation and Modifications of the AASHTO Procedures for Flexural Strength of Prestressed Concrete Flanged Sections

Different interpretations of the equivalent rectangular stress block approximation used by the American Association of State Highway and Transportation Officials (AASHTO) Load and Resistance Factor Design (LRFD) and AASHTO Standard Specifications may lead to inconsistencies in the sectional response of the prestressed concrete flanged sections predicted by the two specifications. According to t...

Non-destructive Impulse Response S’mash Method for Concrete Pile Testing

Nowadays, in the civil engineering practice, the pile-building is the most universal type of foundation. It is usually associated with bridges, fly-overs and other civil engineering objects, industrial buildings, tall buildings, chimneys, tanks etc [1]. It is essential to control the quality of concrete piles. The most accepted weight-bearing capacity measurement technique is the static probe l...
