How to design the Rc-beam Design? - it's parameters
Determine loads & moments
Preliminary (initial) Sizing of element
Flexural Design
Shear design
Detailing
1. Determine loads and moments
-Calculate the Dead-load, live-load.
- Calculate the load combination
-Calculate Factored BM (Mu) +factored SF (Vu)
2. Preliminary Sizing
-Assume beam depth (h) = L/10 ~ L/18
- Assume beam width (b) = 0.5h ~ 0.67h
3. Flexural design
Solve Mu ¢ Vc design stirrups Vs = Vu /¢ - Vc
- Select the stirrups size / spacing
Vs = As × fy x d/ S
ensuring ----
S< min (d/2 , 24")
5. Detailing
-Provide the reinforcement cover ( 1.5 " - indoor beam)
-Check deflection and crack control
( bar spacing < 15" for serviceability)
