<b>NUMERICAL STUDY OF NON-SEISMICALLY DESIGNED RC INTERIOR BEAM-COLUMN JOINTS WITH FULLY-FASTENED HAUNCH RETROFIT SOLUTION</b>

<p dir="ltr">The work follows the study of the behavior of non-seismically designed (NSD) RC interior beam-column joints. Many old RC structures, those bulit prior to 1970's have NSD beam-column joints. During earthquake, these joints are prone to brittle joint shear failure leading to catastrophic collapse of the entire structure. To correctly assess the response of an entire frame structure during an earthquake, the behavior of all joint conditions in a RC structure is needed. Since, most of the researchers have conducted experimental and numerical tests on exterior beam-column joints, this work consists of numerical study of interior beam-column joint with and without Fully Fastened Haunch Retrofit Solution (FFHRS). The numerical model considers realistic modeling of the connection system (i.e., the connection between the steel baseplate with concrete by bonded anchors).</p>
