How to pass a Overstressed Beams in etabs tutorial

[@syivanikhaerunisabudiharjo2774]

thank you so much, your tutorial very helpful for my task. i used SAP2000 and its still work :)

[@EngineeringLearningPlatform]

No problem. Must watch our sap2000 and etabs course on udemy

Since the beams are supported on column....how can you release the moment in the beams ??

[@ashutoshpandya570]

You can release torsion moment in primary beams........ because it comes from the effect of secondary beams flexure moment transfer...... ultimately structure should not become unstable..... check the stability of structure...... 👍

[@MuhammadHashim-d2d]

Thanks for this incredible tutorial. You are doing a great work. I have a question? If the beam fail at 3-4 station loc against the O/S #45 how can this be solved like it passed against the combination but for a specific combination it fails? Is this ok to consider that beam as passed or we need to change the cross-section size?

[@Notjustthatvideo]

Thank you so much brother, because of you my problem is solved

[@theunanimous809]

How can you release moments for all beams... moment release is applicable for secondary beams and for the other main beams as they are rigid there should be negative fixed end moments

[@EngineeringLearningPlatform]

That might be condition for example the positive steel previously was higher to balance the compression steel, now after releasing since there is lower compression steel as we released negative moment hence lesser or no steel at bottom to balance that . But the positive actual steel required increased if u calculate by moment . As the total moment remains wL^2/8

[@santoshgadiya3718]

@@EngineeringLearningPlatform plz Give some More explanation over it...as we always release the moment of Free end and of Secondary Beams... Why to release the moments of all beams..

[@mostafizurrahman6001]

Thanks for sharing ideas. Here you are releasing the negative moment in beam near the support. i.e you are considering beam-column connection as pin connection. But how is this possible in RCC structure? Please explain..

[@EngineeringLearningPlatform]

1. In field the joints will be yeilded when design earthquake arrives . The increased positive moment reinforcement will come to action that time to carryon the dead load . 2. Releasing torsion from beam will make slab transfer very less moments(Torsion for beam) to beam and will be designed for that moment using same model.

[@hossainrakib9027]

1)you apply hinges in the beams but how do you implement that in the field? 2) you guve .001 for torsion how does it effect slab design?

@@EngineeringLearningPlatform.. What will happen if we wantedly release torsion for all the beam.. Will it cause any reduction in strength of structure

[@brynegaexy5246]

I think there is a problem in how you used release moments to solve the issue with the negative moments, by putting hinges and eliminating the excess negative moments give the structure a reaction of a steel structure

[@brynegaexy5246]

Or is this a steel structure? didn't pay attention

[@gaganpatidar9907]

when u release the moment at first u said that there is increase in positive reinforcement. But i can see that after releasing the moment , positive reinforcement further decreased.

Hello, I applied the beam modifyers and some of that beam passed, some still failed due to same Shear force and torsion exceeding its maximum value... How do I fix the problem... Increase in section size didn't work

[@EngineeringLearningPlatform]

Yes increase section size or see shear force diagram at design combo and calculate manually sectional dimensions required .

[@sagurkhan5795]

thanks a bunch for sharing valuable things.. i have few concerns that is 1. whats the purpose use of design system Sds value in the structure?? 2. can I use hinges in the beam in a real structure? if yes then how will be sort of detailing with respect to beam?

[@EngineeringLearningPlatform]

Sds value addition will i corporate Ev _ The vertical component of earthquake in results of EQ cases, while making beam pin-pin releases it from negative moment in top and increasing positive moment in bottom of beam causing bottom steel to increase hence beam becomes strong in resisting the gravitational moment in other way but doesnt matter which way, concern was to increase the capacity which is done . And yes detailing will be for IMRF no special

This will not be useful for earthquake design where we need -ve rft as well.

how to make slab strong enough to take all the torsion and not transfer it to the beams??

Is it high seismic zone? Check the design combination and see moment M3 diagram at that combination to find out behavior

[@varunchhabria1474]

Sir does etabs needs bigger beams and columns sizes than the sizes we use practically??

[@EngineeringLearningPlatform]

No.

[@jahanulreza2636]

what will be the detailing for the moment release beam?????

[@008civ_roufahmad9]

we do not provide the development length when we release the moment in a beam , but in internal supports it is practically difficult to get the beams simply supported . I think this may be the reason.

[@Osama-Anwar]

Change in I for slabs to 0.25 is for flat slabs not for slabs supported on beams.

[@EngineeringLearningPlatform]

For all slabs .

My stair beams are faling due to "shear stress due to shear force and torsion together exceeds maximum allowed". Already provided beam of 12 x 24 inch which seems to me too much for a 6 storied building. Should i release torsion?

1) to pass the OS#45 beam you released T, I22 and I33 0.001, 0.35 & 0.35 respectively... can we release only T to 0.001 and keep I22 & I33 as 1 only is it right or wrong... 2) is it ok to release T, I22 & I33 on few beams (which are failing due to OS45) only and remaining beams can take torsion 3) and also please make a video on "how the design of slab will be affected when we release T, I22 & I33 on beams

@@anand4236 No. It will transfer forces to slab itself, and design slab to take all moment, however don't release from external beams as it is compatibilty torsion and for internal beams can be ignored as balanced from two spans on each side
