Abstract
In order to enhance their functionality and extend their useful lifetimes, structural
components in buildings and infrastructure must be retrofitted. A vital component of many
structures, two-way slabs are typically susceptible to numerous types of degradation,
including cracking, bending, and reduced load-carrying capacity, which can compromise
the operation and safety of the entire structure. This thesis examines Carbon Fiber
Reinforced Polymer (CFRP) systems, an innovative and sustainable solution for
retrofitting two-way slabs. This study's primary objective is to completely evaluate how
CFRP retrofitting techniques enhance the structural performance of two-way slabs. The
study employs an interdisciplinary approach that also incorporates analytical modelling
and finite element analysis. On full-scale two-way slab specimens before and after
retrofitting with CFRP materials, experimental testing will be done to gauge the
improvement in load-carrying capacity, stiffness, and ductility. To fully understand the
mechanical properties of CFRP composites, testing for material characterization will also
be conducted. Analytical models and finite element simulations will be used to forecast
how retrofitted slabs will behave under various loading scenarios. Parametric studies will
be done to optimize the retrofitting properties, such as CFRP orientation, thickness, and
spacing, in order to get the best performance increase. In addition, the economic and
environmental viability of CFRP retrofitting will be evaluated, taking into consideration
factors like a lower carbon footprint and life-cycle cost analysis. Additionally, practical
concerns with CFRP retrofitting will be covered in the thesis, including installation
techniques, quality control, and compatibility with present building materials. Case studies
of actual retrofitting projects will be looked at in order to obtain insight into the practical

application of CFRP retrofitting in different structural configurations and environmental
settings. It is hoped
That the findings of this study would significantly advance the field of structural
engineering. The research's conclusions will assist structural engineers, architects, and
building specialists in making well-informed decisions about changing current structures
to improve their resilience, safety, and sustainability.
