Jul 1, 1999 An iterative procedure is developed to calculate minimum thickness for one-way slabs corresponding to prescribed deflection limits. The minimum thicknesses obtained are compared with values given by the ACI Code. Results of a parametric study are presented showing the effects of design variables on
Definition: Slab is a common term used to describe the structural elements such as floors and roofs where the thickness of the element is very small compared to the length and width. Rectangular Slabs are mainly two types: one-way and two-way. One-way slab means the load is transferred in one direction

Comments: 1. Concrete slabs can't be treated as simply supported. Top reinforcements are needed near the beams. 2. Using applicable codes, live loads and dead loads must be multiplied with certain factors for safety. 3. The effective length of the slab is from the center line of the beam. 4. The typical
identify one-way and two-way slabs stating the limits of ly lx ratios for one and two-way slabs,. explain the share of loads by the supporting beams of one- and two-way slabs when subjected to uniformly distributed vertical loads,. explain the roles of the total depth in resisting the bending moments, shear force and in
determine minimum thickness h. For continuous one-way slabs and beams, determine h based on one-end continuous, since this thickness will satisfy deflection criteria for all spans. The preliminary thickness of a solid one-way slab with normal weight concrete and Grade 60 reinforcement is l 24, where l is the span length
“ONE WAY SLAB IS A SET OF A RECTANGULAR BEAMS SIDE BY SIDE” But How ??? Lets find it….. 9. For purpose of analysis and design a unit strip of such a slab is cut out , which may be considered as a rectangular beam of unit width (say 1ft or 1m) with a depth 'h' equal to the thickness of the slab and
Minimum Cost Selection of One-Way Slab Thickness. Considerable cost savings can result from the design of one-way reinforced concrete slabs, beams of constant width, and footings based on cost minimization techniques of flexural capacity. Equations for minimum cost slab depth are developed and a simple iterative
Rectangular Beams and One-Way Slabs. 2.1 Introduction. This chapter covers the analysis (checking the strength) and the design (sizing the concrete and steel) of reinforced concrete beams and slabs that span primarily one way. The previous chapter . These items exert about 12 13 lb ft2 in. thickness. Thus, a 2 in.
Procedure for Slab Design (One Way). 1). Compute slab thickness according to the table provided by ACI. 2). Compute the total factored load (dead load, self weight, and live load). 3). Compute the ultimate movement (M ) at the ends (negative moment) and the middle (positive moment) using the ACI coefficients. 4).
Minimum thickness for two way slab construction designed as per methods provided by ACI 318-11 Code i.e., direct design method and equivalent frame method.
