In these days, many of high-rise residential buildings are constructing with flat plate slab structure system. These buildings tend to adopt a 'building frame system' and 'dual system' as primary seismic resisting structural system. But, there exist several ambiguities and difficulties in designing theses systems in practical. So, 'KBC2005 & commentary(0306.6.1)' published in 2006 November refer that if the moment frame of 'The dual system(R=5.5)' cannot resist the above 25% of seismic load, it will transfer 'The building frame system' in the form "Immediate moment frame(R=5)"and the shear wall does not have the necessity which will resist completely the seismic load. By appling 'KBC2005 & commentary', flat plate slab structure system are designed according to the method , such as "Deformation Compatibility" and "immediate moment frame(R=5)". 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.
