Abstract: The structural behaviors of rectangular slab-column connections in modern flat plate structures are still unclear due to currently limited experimental data. One of the unclear aspects is the design value of transferred unbalanced moments, which are critical contributor to the connection shear stresses beside the gravity shear stresses. More accurate values of unbalanced moments can be obtained by modeling reduced slab stiffness due to slab cracking more accurately. However, currently available models do not represent the actual behavior of the cracked slab. The objective of this study is to improve the analysis and design of flat plate structure slab-column connections by obtaining representative values of unbalanced moments. It is achieved by proposing reduced slab stiffness model based on the modified effective moment of inertia method. The use of the effective moment of inertia method ensures simplicity and, with appropriate use of parameters, can lead to accurate prediction of reduced stiffness of cracked flexural members. Accurate reduced slab stiffness computation is important in obtaining representative values of unbalanced moments. Unlike currently available models that are only applicable for flat plate structures with regular column layouts, the proposed model is also applicable for irregular column layouts.
