The accuracy of these  design techniques may not be sufficient to ensure an economics and safety design because  important factors are neglected in the techniques. To evaluate the economics and safety of tall  building design based on 2D frame analysis, tall building models with varying building  parameters are tested by 2D frame analysis and more rigorous by 3D analysis. A real case study  of tall building in Thailand are tested also.  The results show that for frame building system without shearwall, a design based on  simplified 2D frame analysis under static or dynamic load is acceptable. Coupled frame-shearwall  building will be over-designed if results of 2D analysis are used especially at lower stories for  building which basically deform in bending mode and of which the number of stories is above  twenty five. Tall building designed from results of a three-dimensional analysis can very well  resist the worst loading condition as expected. Building design based on 2D frame analysis is  partly over-designed and partly unsafe 0aTall buildings 0aStructures, Theory of0 aWorsak Kanok-Nukulchai,eChairperson0 aPichai Nimityongskul,eExamination Committee1 aUeda, Tamon, eExamination Committee2 aThe Government of Japan, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
