Title: Comparison of Analysis Procedures for Two-Way Slabs

Abstract:Two-way reinforced concrete slabs act with columns and walls to form structural systems for resisting gravity and lateral loads. Current analysis approaches for such systems usually involve finite elements or equivalent frames (effective beam widths or equivalent frame properties). Each approach has advantages and disadvantages. As currently used, neither is completely suitable for analyzing two-way slab systems under combined gravity and lateral loads. The development, advantages, and limitations of each approach are discussed, with emphasis on the equivalent frame approach. An equivalent frame analysis method is proposed that involves explicit modeling of attached transverse torsional members. Lateral deflections calculated by various slab analysis methods are compared with published experimental results for a multistory slab system under lateral loads. Slab moments calculated by various slab analysis methods are compared with each other for idealized flat-plate and two-way slab-on-beam structures. The explicit transverse torsional member method is found to give good results for drifts and slab-beam actions, and is recommended for analysis and design of two-way slab systems under combined gravity and lateral loads.
