Moreover, it is observed thatthe structure amplifies the soil uncertainty more than the seismological uncertainty.Furthermore, this dissertation evaluates the economic viability of allowingfor controlled inelastic deformation of special moment resisting buildings during wind storms. This is achieved through a set of case studies involving steelbuildings of varying heights made of special moment resisting frames locatedin three different cities in the United States of America, with different intensitylevels of wind and seismic hazards. It is shown that, controlled inelastic deformation of buildings under wind load may be economically advantageous,depending upon the properties of the structures and characteristics of both hazards.Finally, this dissertation explores financial aspects of selecting retrofit strategies for an interdependent civil infrastructure system subjected to multiple hazards.
