Shear Reinforcement Requirements For High-Strength Concrete Bridge Girders, J. A. Ramirez, Gerardo Aguilar Jan 2005

Shear Reinforcement Requirements For High-Strength Concrete Bridge Girders, J. A. Ramirez, Gerardo Aguilar

JTRP Technical Reports

A research program was conducted on the shear strength of high-strength concrete members. The objective was to evaluate the shear behavior and strength of concrete bridge members with compressive strengths in the range of 10 000 to 15 000 psi. The goal was to determine if the current minimum amount of shear reinforcement together with maximum spacing limits in the 2004 AASHTO LRFD Specifications, and the upper limit on the nominal shear strength were applicable to concrete compressive strengths up to 15 000 psi.

A total of twenty I-shaped specimens were tested monotonically to failure. Sixteen specimens were reinforced concrete ...
