Reinforcement Detailing of Beams from ETABS output

Detail design of beams in Etabs 2018.
The ETABS file for a G+4 building is provided. Run the analysis and design the RCC Moment ResistingFrame. The following challenge deals specifically with two continuous beams in the 1st floor.

1) 3 span continuous beam along grid A
2) 7 span continuous beam along grid 3

Address the following issues thereafter.
• Provide details of longitudinal and shear reinforcement for the two continuous beams. Sketch the beam elevation details or draft it using autocad software. A sample of how beam elevation details is prepared in consultancy firms is provided below. Participants can prepare it as per their preference:

• Provide reasons for failure of the middle span along grid A. What are the possible ways this issue can be resolved?

• Calculate value of the maximum shear force in any one of the spans in both the continuous beams, as per clause 6.3.3 (b) in IS 13920 – 2016. Also, confirm these values from shear force demand calculated by ETABS.Please note that if longitudinal reinforcement provided is more than required (as per ETABS results), the shear force demand will vary from what is provided by ETABS.

ANS-

AIM:-

• To design the beams using Etabs 2018.
• To run the analysis and design the rcc moment resting frame.
• to provide reason for failure of the middle span along grid A.

PROSEDURE:-

• first download the attachment given in challenge .
• open that file in Etabs.

• run the given model.

• after this we need to check the beam design.
• click on concrete frame design.
• select start design.

• after completing go to plan view.

• we need to provide reinforcement details for Grid : A and Grid:3
• to view shear reainforcement follow below steps.
• go to design display info<shear reinforcing.

• by right clicking on beam we can see reinforcing.

• click on details for more reinforceing details.
