| dc.description.abstract | Modern residential buildings have efficient structural systems, and utilize high-strength
materials, resulting in reduced building height, and thus, become more slender and flexible
with low damping. These flexible buildings are very sensitive to wind excitation and
earthquake load causing discomfort to the building occupants. Therefore, in order to mitigate
such an excitation and to improve the performance of tall buildings against wind loads and
earthquake loads, many researches and studies have been performed. Early integration of
aerodynamic shaping, wind engineering considerations, and structural system selections play
a major role in the architectural design of a residential building in order to mitigate the
building response to the wind excitations. A residential building, whose shape is unsuitable,
often requires a great deal of steel or a special damping mechanism to reduce its dynamic
displacement within the limits of the criterion level for the design wind speed.
Understandably, an appropriate choice of building shape and architectural modifications are
also extremely important and effective design approaches to reduce wind and earthquake
induced motion by altering the flow pattern around the building, hence for this research work
four different shaped buildings are generally studied namely L,T,U and square.To achieve
these purposes, firstly, a literature survey, which includes the definition, design parameters,
and lateral load considerations of residential buildings, is presented. Then the results are
interpreted for different shaped buildings and of different stories thereby concluding as to
which shaped residential building is most stable for different conditions.
