Introduction24th December 2004 Tsunami tore apart the west coast of Sumatra causing a Tsunami which took 250,000 lives in 12 countries.

Exposed the 1400 km coastline of Sri Lanka and the economic loss is estimated in more than US $900 million .

Post-Tsunami reconstruction were required to speed up.

Strength and stability of those buildings became a question to know if they are resilient enough to resist future tsunamis forces.

Tsunami loads on buildings Typical tsunami-induced force components include hydrostatic, hydrodynamic, buoyant, drag force, impulsive and debris impact forces.

These loads are calculated from empherical equations derived in previous studies and numerical researches.

This study mainly focuses on the effectiveness of strengthening in the case of critical damage'.

Numerical analysis of tsunami loads Analytical tool and modelling

The building considered in this study is the substandard full-scale two-story one-bay RC frame building.

The structure was subjected to a series of shaking table tests to assess the effectiveness of CFRP strengthening solutions for developing countries as part of the EU-funded Ecoleader project.
