SIR wether we need to count the formwork weight in design of slab and beam of RC structure if not then why what are the ACI LIMITATION why we not counting them because they are so heavy concentrated loads which is applied to the slab
Total beam length = 15.5 ft Beam span ( center to center) = 15.5 -6/12 = 15 ft , Vu max (60 k) was calculated at the center of the bearing - Critical shear design force at d (18") from bearing edge or (18"+ 6"/2) from bearing center . So Vu cr = 60 - 8( 21/12) = 46 k Thanks Sir
This would generally just change your shear diagram, so you would find a new shear diagram with the point load in step 1 and then continue with the rest of the problem in a similar fashion. If the point load is close to the support, you may want to use the strut-and-tie method. See my lecture on the strut-and-tie method for more information on this.
Daivd, you are my go too source, when I am in doubt.
Thanks. Keep up the great work!
Please bring an example of design a section within the plastic hinge length in SMF frame using capacity shear strength for a beam...
It is an outstanding explanation. Thank you!!
SIR wether we need to count the formwork weight in design of slab and beam of RC structure if not then why

why we not counting them because they are so heavy concentrated loads which is applied to the slab
what was the formula for the critical shearing (Vu,cr)?
in T beams do we use bw (middle web width)?
Total beam length = 15.5 ft Beam span ( center to center) = 15.5 -6/12 = 15 ft , Vu max (60 k) was calculated at the center of the bearing - Critical shear design force at d (18") from bearing edge or (18"+ 6"/2) from bearing center . So Vu cr = 60 - 8( 21/12) = 46 k Thanks Sir
How can we solve if any point load present????

Hey David, Concerning flexural design. Would you consider 15.5 ft or 15 ft as the length to M_u?
Thanks man. Great video
15 ft
Don’t get the L span, 6”x2 = 12”=1’
L beam = 15’ -1’ = 14.5’ right?
WHY70122 it’s center to center so 6 inches total. 0.5 ft. 15.5 ft - 0.5ft = 15ft
mlk tua letra nao ajuda, mas te agradeço por qualquer ajuda
