Modeling the post shear failure behavior of reinforced concrete columns
Numerous reinforced concrete buildings vulnerable to earthquake induced collapse have been constructed in seismic zones prior to the 1970s. A major contributor to building collapse is the loss of axial load carrying capacity in non-seismically detailed columns. Experimental investigations have …

Seismic Evaluation of Reinforced Concrete Columns and Collapse of Buildings
There are a large number of reinforced concrete (RC) buildings in seismically active areas of the world that are not designed and constructed in accordance with modern seismic design provisions. These buildings are vulnerable to severe damage or collapse due to their low lateral displacement …

Behaviour of Fibre Reinforced Polymer Confined Reinforced Concrete Columns Under Fire Condition
In recent years, fibre reinforced polymer (FRP) materials have demonstrated enormous potential as materials for repairing and retrofitting concrete bridges that have deteriorated from factors such as electro-chemical corrosion and increased load requirements. However, concerns associated with fire …

Performance of Full-Scale Reinforced Concrete Columns Subjected to Extreme Earthquake Loading
Seven full-scale reinforced concrete (RC) columns were tested at the Multi-Axial Subassemblage Testing (MAST) Laboratory of the University of Minnesota to investigate their performance under extreme seismic events that would produce near-collapse conditions. One of the goals of the tests was to …

A Hysteresis Model for Reinforced Concrete Space Frame Structures
A hysteresis model to simulate the behavior of reinforced concrete columns subjected to biaxial bending and varying axial load is proposed. The model, identified as the U-model, is based on cross-sectional properties. The U-model combines the Otani's modification of the Clough model and the Ziegler …
