In these days, many of high-rise residential buildings are constructing with flat plate slab structural system these buildings tend to adopt a 'The building frame system(R=6)' and 'The dual system(R=6.5)' as primary seismic resisting structural system. But, there exist several ambiguities, difficulties in designing theses systems in practical application. So, 'KBC2009 &
commentary(0306.6.1)' published in 2009 November refer that if the moment frame of 'The dual system(R=6.5)' cannot resist the above 25% of seismic load, it will transfer 'The building frame system' in the form "Immediate moment frame(R=6)"and the shear wall does not have the necessity which will resist completely the seismic load.
By appling 'KBC2009 & commentary', flat-plate structure system are designed according to the method such as "Deformation Compatibility" and "Immediate moment frame(R=6)". The objective of this study was to compare with stress behavior and effectiveness according to two design-method of seismic load resisting system in flat-plate slab.
