Dear viewers, today I have come up with a very useful and informative tutorial especially for Civil Engineers. As we all know that beam is an integral part of a civil engineering structure like a building which may be a home, an office, shopping mall, commercial plaza, hospital, schools etc. Beams take the load of the slab and the structure built over the ground floor or basement and transfer that load to the columns which subsequently transfer whole of the load to the foundation of the structure.
Before starting the design of a beam, you must know the following data you need to input. Find out the factored load.
Find out the moment considering your case. A list of formulas is introduced for different conditions of location of the beam. However we are designing a simply supported beam.
Now find out the reinforcement ratio. For tension controlled failure we use ɸ (phi) = 0.9
Select the reinforcement accordingly.
At the end check your section against minimum reinforcement ratio for flexure and maximum reinforcement ratio for ϵt=0.005. Check the moment against the design moment. If design moment ɸMn < Mu revise the section with greater dimensions.
Here is the Excel Sheet for the design of a rectangular beam. You can edit this sheet by inserting your own load values and other specifications and check if your design is safe or not and hence produce a design that is safe yet economical.
Excel Sheet for Beam Design
This sheet is really gonna prove beneficial for you in your design projects. Do try to make your own design sheet following the guidelines given above, but for this you must have enough knowledge and expertise in Microsoft Excel. Also see other civil engineering softwares tutorials on my blog and make your knowledge overflow 🙂 I would suggest you Safe Tutorial for the design of slab. Learn things with dedication, interest and go ahead to mark your place in this world. Good Luck
