Composite materials are defined as the sum of matrix and reinforcement materials. Hand layup technique is mostly used by researchers for the fabrication of composite. The present work aims to determine the mechanical strength of hybrid composite (flax-glass-epoxy, jute-glass-epoxy, flax-epoxy, and glass-epoxy). Obtained experimental results were validated with finite element analysis using ANSYS software. Analytical study on performance of NSM GFRP bars along with hybrid composite as external strengthening for columns was evaluated using ANSYS software.

Beam-column joint is considered as a crucial zone in moment resisting frames. It is subjected to large forces during an earthquake, due to ground shaking and the response of the building depends on the behavior of the beam-column joint. During analysis, the joints are usually treated as rigid and this fails to consider the effects of various shear forces developed within the joint. So there emerges the need of seismic upgrading owing to structural deterioration, change in functions or increased performance requirements. Damping is one of the commonly adopted methods proposed for achieving optimal performance of the building subjected to seismic actions. In the present study, an economical approach towards the use of dampers in buildings to reduce the seismic effect is studied. A hybrid combination of dampers with steel bracings for retrofitting is studied in this paper. A cost effective hybrid configuration is presented which can simultaneously reduce the seismic effect and the overall cost for retrofitting.

Beam-column joint is considered as a crucial zone in moment resisting frames. During an earthquake, structures are subjected to large forces due to ground shaking and the response of the building depends on the behavior of the beamcolumn joint. In normal analysis, the joints are usually treated as rigid and due to which the effects of various shear forces developed within the joint are not considered. To avoid the failures during earth quake, seismic upgrading is required, for structural deterioration, change in functions or increased performance requirements. Damping is one of the commonly adopted methods proposed for achieving optimal performance of the building subjected to seismic actions. In the present study, an economical approach towards the use of dampers in buildings to reduce the seismic effect is studied. A hybrid combination of dampers with steel bracings for retrofitting is studied in this paper.
