Rehabilitation of RC buildings in seismically active regions using traditional and innovative materials

Abstract

The field of research in the frames of this paper will be Application of Traditional and Innovative Materials for Repair and Strengthening of RC Buildings in Seismically Active Regions. The need for repair and strengthening of RC buildings and their structural elements occurs when their elements are insufficiently strong, stiff and/or ductile out of different reasons or due to slighter or more severe damages most frequently caused by earthquakes. Within the frames of this paper, special emphasis will be put on RC buildings where, during construction, the built-in concrete fails to achieve the designed concrete class and/or buildings that cannot satisfy the required strength, stiffness and deformation characteristics particularly in earthquake conditions due to built additional storeys or enlargements. In these cases, it is necessary to take measures for repair and strengthening of both individual structural elements and whole structures using traditional and Innovative Materials.
