Numerical Procedure to Generate Interaction Diagrams for
Numerical Procedure to Generate Interaction Diagrams for Circular Concrete Columns Wrapped With FRP. Fiber reinforced polymers (FRP) is an attractive material to the field of strengthening and confining new and existing structures. FRP is usually used to wrap columns to increase the ultimate strength and strain of the concrete through confinement.

Seismic behavior of circular reinforced concrete bridge
Reinforced concrete (RC) columns of skewed and curved bridges with unequal spans and column heights can be subjected to combined loading including axial, flexure, shear, and torsion loads during earthquakes. The combination of axial loads, shear force, and flexural and torsional moments can result in complex failure modes of RC bridge columns.
Columns (Chapter 10) - Reinforced and Prestressed Concrete
Because of the interaction between axial force and bending moments, the analysis and design of reinforced concrete columns, subjected to either uniaxial or biaxial bending, are considerably more complicated than the treatments for beams. In addition, the stability of slender columns and problems associated with column side-sway need to be
