Abstract
Concrete is the most frequently used material in the construction material worldwide. High elevation bridges with very large size columns are constructed to accommodate high moment and shear demands. In particular, bridge piers designed in accordance with old design codes may suffer severe damage during seismic events, caused by insufficient shear or flexural strength, low ductility and inadequate reinforcement anchorage. Many parameters may influence the overall hollow column response such as: the shape of the section, the amount of the longitudinal and transverse reinforcement, the cross section thickness, the axial load ratio and finally the material strength of concrete and reinforcement. This paper focuses on circular hollow cross sections and investigates the columns behavior under a state of compression. The experimental results have been compared with solid sections on the behavior of the hollow column strength of concrete M20 grade concrete mix designed as per I.S. 10262-1982 method.
