Reinforcement Detailing of Beams from ETABS output

Aim:

To determine the project is Reinforcement Detailed design of concrete buildings

Introduction:

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

Procedure:

1. This is in mumty level and It is changed to 1st floor level where the two beams are located and have to design 3 span continuous beam along grid A and 7 span conitinuous beam along grid 3.

2. One the Analysis has been completed we get the status of Maximum and Minimum deflection at the left side status bar and by clicking concrete frame button in top right option which will design the longitudinal reniforcement and shear reniforcement for all the frames, Frames includes beams and columns.

3. After completing the cement concrete design check, now its showing the longitudinal reinforcement for the all the beams in te first floor level. and the screen shot is given below.

4. In this image we see the left support top recuirement, Left support bottom recuirement, and mid span to and bootom recuirement and right support top recuirement and left top support recuirement.

5. The display design Info, changed the design output into shearing reinforcing and clicked apply but we get the shear reinforcing in multiples of 10.

6. We have to check the detail of the perticular section in concrete beam design information by right clicking on the beams to know the units of figures.

7. To check why the mid span along is failed O/S this means over stressed, concrete beam design information by right clicking on the beams we can see the shrear stell is not calculated at the three combinations.

8. Open the details and shear deatils in the bottom we get some error maximum load details. the shear stress is nothing but Load/Area, one thing we have reduce or increase the loading,

9. This is the ETABS model provided for the extra combination dead load sway shear force, In load combination tab we have provide the shear in the sway formula.

Result

10. This is the result for the sway case checking in member force diagram for frames/piers/spanderls/links, Load case as sawy case. we can chell all the result like this in ETABS
