This work deals with an elastostatic, dynamic analysis of industrial buildings using the finite element method. The structural modeling for the beam-slab building is made by using frame finite elements to frame building sub-system and flat shell elements for the ( membrane plus flexure behavior) slab structural subsystem. Then, the coupled threedimensional structure is analyzed on a fully integrated way, so that sub-structural interactions are simultaneously taken into account. The bending effects in frame elements are based on Timoshenko beam theory where shear deformation is incorporated. The flat shell element assemblage is made by superposition membrane problem (using the classical 2D plane element CST) and bending problem (using DST element) in order to incorporate the shear deformation effect. Another focus of this work is concerned to study displacement changes due to excentricity between the beam neutral line and the plate median plane. In this work the dynamic analysis of beam-slab building and its structural subsystems is restricted to natural frequency evaluation. For these analyses both shear deformation and rotator inertia effects for mass matrix computation are taken into account for frame and flat shell elements. Numerical examples are presented and compared with other results taken from literature or run from commercial structural analysis packages.
