Can u show me how joint reinforcement detailing is done for released and unreleased moment? Thanks. =)

brick2011, oh. . I see.. Does that mean if I don't provide full Ld on my concrete beam supports, no moments will be transferred to the adjacent frames because it will behave as simply supported? In that case, If we want a fixed support we provide full Ld, For simple support don't provide full...

Thank you all. I highly appreciate all your comments.. =)

IDS, I use the method mentioned by TLHS if both compression & tension bars yield. If only the tension bars will theoretically yield, I would use the Moment Capacity contributed by the Concrete block and compression steel bars with yield stress lesser than Fy by summing up moments about the...

Thank you very much... If I understood it right, fixed support for concrete frame element can be replaced with pin connection to eliminate torsion in case of secondary to main beam, and so that there would be no moment transferred to core wall if it is applied on the weak axis.. If we made...

TLHS, This is the method I use to verify beams adequacy against moment. The method for the first case uses the difference between tension and compression bars which is 3-2 = 1. If both top & bottom bars are equal, the difference would become zero. If it is zero, then I'll assume compression...

Thanks to you all. you're all great! =)

Thank you very much. =)

Thank you very much for the response. =)

Hello Everyone, I wish to hear your ideas and experiences about these things. =) 1 - When you design concrete beams, should you always consider deflection? 2 - If the beam is adequate against shear and moment, isn't that already enough? 3 - Does deflection affect beam capacity performance...

Thank you for your kind respond. I so appreciate it. =) 1 - Is it even allowed to change the support condition of concrete frame element from fixed to pin? 2 - I saw some designers applying end releases on edges of concrete beams & columns if it is not a cantilever, is that allowed? This will...

CAN SOMEBODY EXPLAIN TO ME THE REASON OF USING A TYPICAL 30% SUSTAINED LIVE LOAD USED IN COMPUTATION OF CONCRETE BEAM DEFLECTIONS? THANKS. =)

HELLO EVERYONE. I WOULD TO HEAR YOUR IDEAS ABOUT THE USE OF "END RELEASES" IN ETABS. 1 - WHEN IS IT ALLOWED TO BE APPLIED IN BEAMS AND COLUMNS? 2 - AREN'T THE CONCRETE BEAMS AND COLUMNS SUPPORT SHOULD ALWAYS BE FIXED? 3 - CAN SOMEBODY TELL ME THE PURPOSE WHY WE SHOULD PUT END RELEASES? THANK...

Hello Everyone. I would like to hear your ideas about doubly reinforced beams that has equal amount of reinforcement in compression and in tension. Is that ideal or no? Thank you. =)
