Impact on the building performance of subsequently cast concrete

Abstract

There are many examples about building stock grows uncontrollably and irregularly in Turkey which is called unplanned urbanization. A serious part of this building stock which is growing uncontrolled is created by the structures called '' slum ''. In this type of construction, the quality of the used concrete is low as well as poor workmanship. Over time, when these structures become inadequate to serve the purpose, additional floors are being constructed, either controlled or uncontrolled. In this study, it was tried to determine the effect of the concrete quality used in the later constructed floors and the concrete classes used in the original construction on the building performance. For this purpose, a 5 story reinforced concrete structure; It is aimed to determine the structural performance of the C14 and C25 concrete classes using different floors and different variations by static pushover analysis.
