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...

متن کاملFlexural Performance of High-strength Prestressed Concrete-encased Concrete-filled Steel Tube Sections
The sections composed of concrete and steel, which include concrete-encased concrete-filled tubes, generally have defects due to the low tensile strength of concrete. Therefore, an appropriate method was used for the combination of concrete-filled tubes (CFT) and prestressing strands which is encased in concrete. The conventional design guidelines are commonly developed for materials with norma...
متن کاملDuctility of Prestressed and Partially Prestressed Concrete Beam Sections
D analyses of structures responding elastically to ground motions recorded during severe earthquakes have shown that the theoretical response inertia loads are generally significantly greater than the static design lateral loads recommended by codes. Hence, structures designed for the lateral earthquake loads recommended by codes can only survive severe earthquakes if they have sufficient ducti...
متن کاملEvaluation 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...
