Abstract
Combined Bending and Axial Compression for irregular shaped (such as L-shaped, Channel shaped, T-shaped) reinforced concrete short column is a common design problem. Current code provisions and the available design aids do not offer an insight into the determination of strength and ductility of biaxially loaded reinforced concrete columns. The reason is that the information on the behavior of irregular shaped reinforced concrete members under combined biaxial bending and axial load is not well known. They are usually overdesigned and this may cause the structure to be stiffer, which may result in loss ductility when applied to seismic regions. Thus the primary objective of this thesis is to address the strength and deformational behavior of irregular shaped reinforced concrete members under combined loading.
Here different shape of reinforced concrete columns are analyzed by ACI Handbook or CRSI Handbook method using an equivalent rectangular column method. These results are compared with analytical and test results of other investigators. The studies show that an equivalent rectangular column section, representing some typical channel and T-shaped sections, can reasonably predict the ultimate strength capacity of channel and T-shaped reinforced concrete short and tied columns under combined biaxial bending and axial compression.
