~ * Subroutine Name : RECTAH ("' RECTANgular section)

Purpose : To determine the amount of bending reinforcement

for a rectangular beam section.

Com* Reference : Section 4.7 of Chapter 4.

SUBROUTINE RECTAH (B, BETAB, D, DDASH, FCU, FY, KDASH, H, X, Z,

' AS, ASDASH, FSDASH, MU)

~ • • • • • Input parameters

REAL B, BETAB, D, DDASH, FCU, PY, KDASH, M, X, Z

~ • • • • • Output parameters •

REAL AS, ASDASH, FSDASH, MU

~ ---------------------------------------------------------------

~ I calculate the moment capacity due to concrete Mu in Hmm.

~ I from Eqn 4. 7-4 of Chapter 4.

~ ---------------------------------------------------------------

MU = KDASH * FCU * B * D ** 2

~ ---------------------------------------------------------------

~ I Check the moment capacity of the concrete Mu.

~ ---------------------------------------------------------------

IF (M * l.OE6 .LE. MU) GO TO 100

IF (M * l.OE6 .GT. MU) GO TO 200

Com ---------------------------------------------------------------

~ case 1 : Ultimate moment M is less than or equal to Mu.

Com The section is to be singly reinforced.

~ calculate the minimum amount of tension steel required from

~ Eqn 4. 7-9, see St.ep 2 of Section 4. 7 in Chapter 4.

~ ---------------------------------------------------------------

100 AS = M * l.OE6 / (0.87 * FY * Z)
