Development of an effective slab width design equation for reinforced concrete coupling beams in flat plate structural systems using a three-dimensional finite element method

Coupling beams represent an essential structural member for reduction of the bending moment and increased energy dissipation capacity in a coupled shear wall. Flat plate structural systems are frequently used for calculation of floor height and room space. In this study, the effects of reinforced concrete coupling beams with respect to flat plate structural systems are discussed. Additionally, the coupling beam and slab size for use in flat plate structural systems are investigated. Examined parameter variables include beam width, slab width and slab thickness. Non-linear three-dimensional finite element analyses have been effectively employed in the development of a design equation for the calculation of effective slab width.
