im sorry. it's not Vc/bwd but Fv = (phi)(0.17)(lambda)sqrt(f'c) rather (in SI units).
@DaveAtkins is averaging shear values an acceptable method? is there any provision from any code that allows us to get the average shear for our design? if yes, then i think it will help me on my current...
where should i compare the values of SQx and SQy? is it only for fv = Vc/bwd?
what if concrete shear capacity is not enough? what can i do?
how can i design link bars to increase shear capacity?
i am currently investigating a wall footing. from the natural grade, they elevated the area by 1.5m. the designer rests the wall footing by 0.6m from finish grade, which means that it doesn't rest on the native soil. is that okay? aren't we expect a large immediate settlement for this?
can we recommend that column footings may rest on compacted backfills? is it common to practice? do we need to do geotechnical tests to compute for the bearing capacity of backfill?
