This research includes a theoretical investigation about the behaviour ofsimply supported composite slim floor beams with partial interaction. For thepurpose of analysis, the slim floor slab system is simplified to a multi-layeredcomposite beam. The slim floor beam is embedded in concrete. Therefore, thelayers of the slim floor are connected together by natural shear bondgenerated between the steel and concrete and distributed uniformly along theinterface without using shear connectors. Linear behaviour with one degree offreedom of the slim floor (slip only) without separation is studied according toJohnson and May approach using different material properties and differenttypes of loading.Equilibrium and compatibility are satisfied for the forces and displacementsat an assumed element to arrive at two differential equations of second-orderin terms of slip and axial force. The equations are solved numerically usingthe finite difference method. A computer program is written in Visual Basiclanguage to solve the problem.The current model is applied to three typical simply supported slim floorbeams tested experimentally by “Corus Construction Center”. The modelshowed close prediction with the observed results.
