  • Abstract:
    This report presents the analytical study of the shear capacity of reinforced concrete columns using both the AASHTO LRFD Bridge Design Specifications and the AASHTO Guide Specifications for the LRFD Seismic Bridge Design. The study investigates various levels of axial load, transverse reinforcement and longitudinal reinforcement to determine how the two specifications compare. The AASHTO Guide Specifications for the LRFD Seismic Bridge Design permits the designer to use the AASHTO LRFD Bridge Design Specifications or equations within the AASHTO Guide Specifications for the LRFD Seismic Bridge Design with predetermined values. In order to develop a comprehensive understanding of shear behavior, in addition to examining conventional reinforcement, the comparison will also be conducted on high strength concrete and reinforcement. Experimental data is limited for high strength concrete and reinforcement columns, but some test points will be provided to compare with the models. A database of numerous tested reinforced concrete columns, including conventional and high strength reinforcement, was developed. A list of shear equations was used to predict shear strength, which shows how the concrete and reinforcement shear capacity was predicted using shear equations. The key parameters investigated are column axial load, amount of transversereveal differences in predicted shear strengths. A parametrical study was extended to conventional full-scale columns, using both the AASHTO LRFD Bridge Design Specifications and the AASHTO Guide Specifications for the LRFD Seismic Bridge Design to predict shear strength in order to analyze the direct effects of the parameters on the shear strength predictions. and longitudinal reinforcement and deformation ductility demand.
