Earthquakes are the most critical loading condition for all land based structures located in the seismically active regions. A recent earthquake in India on January 26th, 2001 caused considerable damage to a large number of RCC high-rise buildings and tremendous loss of life. The reasons were (a) most of the buildings had soft and weak ground storey that provided open space for parking, (b) poor quality of concrete in columns, and (c) poor detailing of the structural design. Therefore, this incident has shown that designers and structural engineers should ensure to offer adequate earthquake resistant provisions with regard to planning, design and detailing in high rise buildings to withstand the effect of an earthquake. As an earthquake resistant system, the use of shear walls is one of the potential options. The use of shear wall-buildings is quite common in some earthquake prone regions. Shear walls majorly resist the seismic force, wind forces and even can be build on soils of weak bases by adopting various ground improvement techniques.
