PREDICTION METHOD FOR SEISMIC DAMAGE OF REINFORCED CONCRETE BRIDGE COLUMNS

Seismic Response of Reinforced Concrete Columns

There are a large number of reinforced concrete buildings in seismically active areas of the world that are not built in accordance with modern seismic design provisions such as those published by American Concrete Institution ([ACI] Committee 318, 2008). In the United States and other parts of the developed world, these buildings were constructed between 1930s to mid 1970s according to the bui...

Yield curvature for seismic design of circular reinforced concrete columns

Seismic Behavior of Steel Reinforced Concrete Beam-Columns and Frames

The ability to perform accurate nonlinear simulations is a key component in the assessment of the behavior of seismic force resisting systems. A three-dimensional distributed plasticity formulation for composite beam-columns suitable for nonlinear static and dynamic analyses of composite seismic force resisting systems has been developed. New uniaxial constitutive relations are developed for th...

Identification of Damage in Reinforced Concrete Columns under Progressive Seismic Excitation Stages

Prompt and accurate detection of realistic damage in constructed facilities is critical for effective condition assessment and structural health monitoring. This paper reports the experimental investigations of eccentric reinforced concrete columns mounted onto a shaking table and subject to progressively increasing seismic excitations. The investigation was aimed at studying the changes in the...

Rehabilitation of Reinforced Concrete Columns

In recent years, rehabilitation has been the subject of extensive research due to increased spending on building work and repair of built works. In all cases, it is absolutely essential to carry out methods of strengthening or repair of structural elements, and that following an inspection analysis and methodology of a correct diagnosis. The reinforced concrete columns are important elements in...
