Project Overview
Recent seismic events and escalating energy demands have exposed major shortcomings in the existing building stock, particularly in older structures that lack both seismic resilience and thermal efficiency. Conventional retrofitting approaches typically address these challenges separately by applying structural reinforcement and thermal insulation in discrete layers resulting in complex, time-intensive, and often inefficient interventions. To overcome this limitation, the present research proposes the development of an innovative Polymer Matrix Composite (PMC) panel system that integrates both seismic strengthening and thermal insulation functionalities in a single, prefabricated retrofit solution. The primary objective of this project is to design, develop, and experimentally validate PMC panels made from rubber/plastic-based polymers, reinforced with glass or carbon fibers, and thermally efficient fillers such as silica. These panels will be characterized for mechanical and thermal properties and attached externally to walls using adhesive mortar. Sub-assemblage tests (flexural and diagonal tension) and pseudo-static cyclic loading of six half-scale wall specimens will be conducted to evaluate structural improvements. Simultaneously, thermal conductivity, specific heat, and U-value assessments will determine energy performance. The hypothesis to be tested is that an integrated, composite retrofit system can simultaneously enhance both seismic resistance and thermal efficiency of masonry structures. Finite Element Modelling (FEM) and energy simulation tools will complement experimental findings to optimize design through parametric analysis. The project may significantly advance the construction field by establishing a unified retrofit methodology that is structurally robust, energy-efficient, and industrially scalable. The outcomes will contribute to safer, climate-resilient buildings while aligning with national goals for sustainable infrastructure and disaster risk reduction.
