How do you calculate thickness (depth) of one-way slab? For solid non-prestressed slabs not supporting or attached to partitions or other construction likely to be damaged by large deflections, overall slab thickness (h) shall not be less than the limits in Table-1, unless the calcu­lated deflection limits of 7.3.2 are satisfied.

2021年9月12日 · This calculator uses 35% of balanced rebar area as the steel area for design of slab. If Steel grade 60 is to be used, the minimum slab thickness is taken as L/20 where L is the span of slab. If the steel grade is other than 60 ksi, this value of minimum thickness is multiplied by a factor (0.4 + 0.01 f y ) where f y is in ksi.

What Is One Way Slab? When a slab is supported on all four sides and the ratio of long span to short span is equal or greater than two, it will be considered as one way slab. The load on the slab is carried by the short span in one direction.

2024年9月14日 · Here you can get a free excel sheet where a engineer easily design one way or two way slab by one click. We also explain a slab design example in this excel sheet. Slab Dimensions: Applied Loads: Concrete Strength = 2.5 ksi. Steel yield strength = 60 ksi. Design Moments. Loads: Short Span Moments: Reinforcement Calculations. = 0.08 k/ft <5.1 k/ft….

2024年3月29日 · This calculator uses the formula t = sqrt((w * l^2) / (f_ck * b * (f_y / gamma_c))) to calculate the thickness of a simply supported one-way slab. Related Questions Q: What is the importance of slab thickness in structural design?

UBC recommends minimum thickness of Concrete floor slabs supported directly on the ground to be 89mm, whereas BCGBC4010A - Apply structural principles to residential low-rise constructions determined minimum thickness to be 100mm.

Mu = φ ρ fy b d2 [1 – (0.59 ρ fy/fc’)] Solve the quadratic equation of ρ. You will get two values of ρ. Accept the value of ρ which satisfies ρ min <= ρ <= ρ max . If none of the values satisfies, you need to change d. Select bar size and spacing Check: Bar …

ar, it is easy to get an effective depth value. If we assume the use of #4 bars, e.g., in a slab which is 5 in thick, the d value will be 5 in les.
