| dc.description.abstract | Flat slabs can be analyzed by finite element method or equivalent frame method . Computer application of frame analysis method requires that each equivalent frame geometry, material characteristics and member properties be defined effectively. Two simplified methods exist, namely the effective beam width method and the equivalent column method, in which the effect of the slab is accommodated by appropriate modification of the beam width or the column stiffness, respectively. In this study an idealized flat plate slab system under gravity loading only is analyzed using equivalent frame method and finite element analysis method. Effective beam width modeling method is used for equivalent frame analysis method. Comparisons are made for slab moment, column moment and reaction force results with nonlinear finite element analysis results. The results suggest that two dimensional equivalent frame method, that consider nonlinearity effects, is effective in determining slab moments only. Three dimensional equivalent frame method underestimate slab and column moments. Linear finite element analysis method can be used to analyze slab and columns by modifying the stiffness of the slab only. Generally, Consideration of nonlinearity effect is important when analyzing flat plate slab system, both for the slab design to be economical and for the column design to be safe. It is recommended to use load pattern while analyzing columns of flat plate slab system building. | en_US |
