Uniaxial Bending of Columns
Publication: Journal of Structural Engineering
Volume 119, Issue 4
Abstract
An alternative technique is presented for the design and analysis of uniaxially loaded, reinforced‐concrete columns. The technique is based on a simple transformation concept in which the components of the cross section are transformed into an equivalent homogeneous elastic material. The modulus of elasticity of concrete as defined by the ACI code is used as the base for transformation. The pertinent elastic properties of the transformed cross section are evaluated and thereafter the classical bending theory is applied. Furthermore, an interaction formula that could be used to assess the performance of uniaxially loaded column is presented. Also, the strength‐reduction factor is reevaluated with reference to the available ductility expressed by the neutral‐axis‐to‐depth ratio. The results obtained using the proposed technique are in total agreement with those obtained using the conventional ACI code approach. A flowchart showing the iterative process is presented.
