Book Description
Reinforced concrete columns play a very important role in structural performance. As such, it is essential to apply a suitable analytical tool to estimate their structural behaviour considering all failure mechanisms such as axial, shear, and flexural failures. This book highlights the development of a fiber beam-column element accounting for shear effects and the effect of tension stiffening through reinforcement-to-concrete bond, along with the employment of suitable constitutive material laws.

Book Description
The ACI 318-19 provisions for computing the one-way shear capacity of non-prestressed reinforced concrete (RC) columns are primarily based on the results obtained from the RC beams. These equations were introduced in ACI 318-19 to account for the effects of the longitudinal reinforcement ratio, the depth of the column, and the applied axial load on the overall shear capacity. In this study, a column database was developed and used to evaluate the accuracy of the one-way shear provisions. Then, the ACI 318-19 shear capacity equations were evaluated by using the test results for non-prestressed RC columns. The results showed that these relationships significantly underpredict the actual shear capacity of the columns obtained from the test results. To improve the accuracy of the shear capacity equations, a new relationship is proposed and discussed in detail.

Book Description
Abstract: "An experimental study was undertaken to investigate the cyclic strength and ductility of composite columns subjected to simulatedseismic loading conditions. Eight two-thirds scale specimens were tested, each consisting of a structural steel shape encased in reinforcedconcrete. Parameters studied in the test program included: the degree of concrete confinement required to achieve adequate ductility; the effectiveness of shear studs for developing flexural stiffness and capacity under combined loading; the distribution of transverse shear resistance among the elements of the composite column; and concrete compressive strength. The results of the test program indicate that composite columns possess exceptional ductility and strength under cyclic loading if the buckling of longitudinal reinforcement is inhibited. Furthermore, the steel shape provides the primary resistance to transverse shear during overloading, and shear studs are not effective in enhancing the resistance against lateral loading. The elastic secant stiffness of the composite section corresponding to initial yielding of the longitudinal reinforcement was found to be well approximated by using one-half the gross moment of inertia (0.5I[subscript g]) in conjunction with Young's modulus for concrete. A prediction method based on superimposing the individual strengths of the reinforced concrete and structural steel shape was found to provide good agreement with test results. Current AISC LRFD provisions were determined to grossly underestimate the flexural capacity of the test specimens, which were axially loaded to 20% of their nominal pure axial load capacity [sic]."
