The flexural strength of multistory flat-slab buildings subjected to combined vertical and horizontal (sidesway) loadings is investigated by inelastic theory. It is postulated that the columns will be made strong enough so that failure will occur in the slabs. Yield-line theory is used to determine the flexural strength of the slab-column joints and to analyze the overall flexural collapse mechanisms of the slabs when the structure is subjected to the combined loadings. Equations and graphs are presented that will also facilitate the limit design of orthotropically reinforced slabs against sidesway-type flexural failure of both the slab-column joints and the overall slab structure. The bending moments for which the columns must be designed are also obtained in the course of the slab-design process.
