Effect of Concrete Cracking on the Lateral Response of RCC Buildings

In the present study, the effect of concrete cracking on the lateral response of buildingstructures has been investigated and discussed. The research work related to the study of effect of concrete cracking on its stiffness has been surveyed. The controversies in theexpressions of the prime parameter related to the cracking of the reinforced concrete are also discussed. The modification factors and equations recommended in literature as well as in different country standards to introduce the non-linearity of concrete are also given. The framed building design examples are presented for quantitative effect of lateral response incorporating the concrete cracking under seismic loading based on Indian seismic code.
