Two Way RCC Slab Designer | IS Code – 456:2000 This tool helps you to Design two way slab based on IS Code 456:2000. Fill all red Coloured details below & Proceed Types of Slab: One short Edge Continous One Long Edge Discontinous Two adjacent Edge discontinous Two short Edge discontinous Two long Edge discontinous Three Edge Discontinous (One Long edge Continous) Three Edge Discontinous (One short edge Continous) Four Edge Discontinous Interior Panels Shorter Clear Span (lx): meter Longer Clear Span (ly): meter Width of Beam in Shorter Span: mm Width of Beam in Longer Span mm Basic Value (k) (35 to 40 Reccomended) Reccomended Effective Depth of slab mm …………………………………………………… Assume Effective Depth of slab mm Input Clear Cover of Slab: mm Overall Depth of slab mm Effective Span (lx) m Effective Span (ly) m Status …………………………………………………… Live Load: kN/m² Floor finish Load: kN/m² Self load taken kN/m² Total Factored load kN/m² …………………………………………………… Bending moment coefficient (Table-26, IS 456:2000) *Input Values Below according to (ly/ly) and Type of Slab Selected from IS Code Table: See Table (ly/lx) is between: & αx(-)l: αx(-)h: αy(-) : αx(+)l: αx(+)h: αy(+) : (+)ve Moment in Shorter Span: kN-m (-)ve Moment in Shorter Span: kN-m (+)ve Moment in Longer Span: kN-m (-)ve Moment in Longer Span: kN-m Maximum Moment: kN-m Shear Force (Vu): kN-m …………………………………………………… Check for Depth of Slab Select Rebar Fe 250 Fe 415 Fe 500 Strength of Concrete (fck): M Minimum Depth of slab required: mm Depth of slab Provided: mm Status xu,max/d: mm Mu,lim: kN-m …………………………………………………… Design of reinforcement (-ve) Along x-direction Strength of Rebar (fy): Area of steel Required: m² …………………………………………………… Assume Dia of Bars: mm Spacing of Rebar required: mm …………………………………………………… Provided Spacing of Rebar: mm Area of steel provided: mm² …………………………………………………… Design of reinforcement (-ve) Along y-direction Area of steel Required: m² …………………………………………………… Assume Dia of Bars: mm Spacing of Rebar required: mm …………………………………………………… Provided Spacing of Rebar: mm Area of steel provided: mm² …………………………………………………… Design of reinforcement (+ve) Along x-direction Area of steel Required: mm² …………………………………………………… Assume Dia of Bars: mm Spacing of Rebar required: mm …………………………………………………… Provided Spacing of Rebar: mm Area of steel provided: mm² …………………………………………………… Design of reinforcement (+ve) Along y-direction Area of steel Required: m² …………………………………………………… Assume Dia of Bars: mm Spacing of Rebar required: mm …………………………………………………… Provided Spacing of Rebar: mm Area of steel provided: mm² …………………………………………………… Check for Shear 𝜏v : N/mm² Percentage of reinforcement (100*Ast/bd): % Grade of Concrete: M …………………………………………………… *Input Values Below according to (100*Ast/bd) & Grade of Concrete from IS Code Table: 𝜏c (From Table-19, IS 456:2000): See Table P1 M1 P2 M2 *Input Values Below according to Depth of Slab from IS Code Table: Ks (From clause 40.2.1, IS 456:2000): See Table 𝜏c’ N/mm² Status …………………………………………………… Check for Deflection (l/d) Provided N/mm² Steel stress of service load(fs) : Percentage of reinforcement: …………………………………………………… *Input Values Below according to Reinforcement Provided from IS Code Figure: Modification factor (k) (From figure-4, IS 456:2000): See Figure Allowable (l/d) ratio: Status Print this page How to use slab designer tool? Fill all the input boxes with a red-colored line and then press proceed button from starting to end.All the red colored lines are to be filled according to requirement and IS Code 456:2000.At last check for shear, deflection, and depth of slab are ok or not.If you passed all checks, then make detailing of slab reinforcement according to negative and positive reinforcement provided by the tool above.
