Transversely Loaded Horizontally Curved R/C Slabs
Publication: Journal of Structural Engineering
Volume 112, Issue 6
Abstract
A practical and simplified method for the analysis and design of continuous and horizontally curved two‐way reinforced concrete floor slabs is presented. The slab panels are assumed to be uniformly loaded and supported on all sides by rigid boundary supports (beams or walls). The method is based on the use of design moment coefficients that are derived from the classical elastic theory of curved plates. Continuous edges are treated as clamped, and discontinuous edges as simply supported. Twelve possible combinations of clamped and simply‐supported boundaries are considered. The positive and negative design bending moments in the radial and angular direction are obtained from the corresponding moment coefficients and proportioned to middle and column strips. Circular and horizontally curved floor systems are treated to illustrate the use of the proposed method in design practice. The proposed method is similar to the one developed by Marcus for the design of two‐way rectangular slabs which was later adopted by ACI 318‐63 in Section A2003 as “Method 3.”
