Hi Sir! Question. If fs isn't given, you are suppose to use fs=0.50fy. Where does fy come from?

[@CALQARE]

fy is given for that case. In actual practice, it can be found at the specs of steel bar, based on what grade your reinforcement is.

[@CALQARE]

You can also find it at the tip of your steel bar. In problems, fy is given.

SIR ASK KO LNG MERUN PO BA KAYO SAMPLE PROBLEM NG BEAM DESIGN NA MERUNG WATER CEMENT RATIO COMPUTATION NA INCOUTER KO PROBLEM NA YUN NG COLLEGE, NAKALIMOTAN KO LNG

Sir pwede na ang value of d kay 494mm instead of 496mm? since it's still divisible by 2

[@CALQARE]

Yes.pwedi. depende na sa judgment sa designer

[@Kizerlk07]

Also sir, how to solve for h (beam cross section height) after determining the value of d

[@CALQARE]

For one row of bars, since centroid acts at the center of bars Overall height = eff.depth + (dmain/2) bar +dstirrup + conc cover For case of two or more rows of bars, effective depth is from the topmost fiber of concrete down to the CENTROID of bars.
