How to detail Beam Reinforcement

Structural Detailing of beam is an essential skill for entry level civil engineers. Reinforcement detailing is not generally taught in any of the civil engineering design courses. Any civil engineering job especially, site engineering job need a thorough understanding of reinforcement detailing and bar bending schedule preparation.
There are many detailing tools like Revit and AutoCAD that can be used for beam rebar detailing. However, without an in-depth understanding of code provisions for detailing of rebars, one cannot prepare a drawing that can be used at site, good for construction. An expertise in rebar detailing means a lot of technical understanding that is useful, correct, practical and sometimes accurate as in the case of pre-cut bars where we prepare bar bending schedules and pre order bars that are delivered at site and used at construction sites with very minimal manual intervention.
understanding of code provisions for lap locations, the methods for detailing, appreciating the need of economising by reducing the quantity, understanding the standard or stock length of rebars are all very important to finalise a beam detail.
In addition to this, the structural engineer or the drafting engineer need to know the
• minimum steel provisions
• maximum allowable percentage of the rebars
• maximum allowable spacing
• minimum needed spacing
• Where you can lap rebars
• Where you should not lap
• Any additional rebar detailing rules
• If side face rebars are needed
• If you need two layers of rebars or one layer or three
• If you need two bars in a layer or three or more
• The ways of curtailing the bar to have economy
In this video, the focus is on the rebar detailing methods, curtailment lengths and rules and what SP34 – The design aids for IS 456 talks about rebar detailing.
A complete explanation is provided to a student’s doubt on if two rebars need to be adopted or three number of rebars in a layer. A comparison and explanation of both these detailing is provided with full information in this video.
Rebar needed for stress reversal as well as due to compressive steel requirement is explained with examples.
This video is comprehensive and you can detail beams with ease after watching this video.
