Behavior Of Thin-Walled Channel Shaped Reinforced Concrete Columns Under Combined Biaxial Bending And Compression, Subash Yalamarthy
Behavior Of Thin-Walled Channel Shaped Reinforced Concrete Columns Under Combined Biaxial Bending And Compression, Subash Yalamarthy
Theses
Next to rectangular, circular and L shapes, Channel section may be the most frequently encountered reinforced concrete columns since they can be used as box wall for elevators. Nevertheless, information about the load deformation behavior is not generally available to structural engineers. Most of the investigations have been emphasized on the ultimate strength of column sections under combined biaxial bending and axial compression and the resulting interaction surface. No attention is paid to load deformation behavior.
Current code provisions do not provide adequate guidelines for assessing the strength and ductility of biaxially-loaded reinforced concrete columns. Therefore, this investigation is aimed …
Behavior Of L-Shaped Reinforced Concrete Columns Under Combined Biaxial Bending And Compression, Amar Shah
Behavior Of L-Shaped Reinforced Concrete Columns Under Combined Biaxial Bending And Compression, Amar Shah
Theses
Combined biaxial and axial compression for L-shaped reinforced concrete short columns 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 column. An experimental and analytical investigation of the moment-deformation behavior of biaxially loaded L-shaped short columns were undertaken. Four 1/2 scaled specimens were tested till failure. Moment-curvature and load-deflection curves were developed from the experimental and the analytical results. The analytical results were obtained using a computer program developed by Hsu (1). From the investigation it is deduced that …
