CALCS PROC007
FLANGE BEARING DISSIPATION

NOTATION

tethickness, effective
twthickness, web

Pnormal force

APPLICATION

Beam flange subject to normal force, supported by web. Found where beams bear on one-another.

OUTPUT

Web compression stress. Local stability not accounted for.

SEE ALSO

other porcs & progs

THEORY

BS5400

GUIDANCE

Requires DIM T(Nt). Flange dissipation effectivity is reduced as they do not act as a single bending section. This is not accounted for in the BSs.

INPUT FORMAT

LET Nm=:Nk=:Nt=:T(1)=:T(2)=:T(3)=:xbrg=:Tw=:P=:PROC007

EXAMPLE

Call Statement

LET Nm=1:Nk=1:Nt=3:T(1)=.5:T(2)=.4:T(3)=.6:xbrg=5.5:Tw=.3:P=5.4:PROC007

Output

PROC007 FLANGE BEARING DISSIPATION, Rev 190995
sum= +T(1)^3+T(2)^3+T(3)^3= 0.405
Te= (sum)^(1/3)= 0.7399
xw= xbrg+2*Te/TAN(RAD(30))= 8.063
fd= P/(xw*Tw)= 2.232
UF= ABS(fd)/(Kc(Nk)*Fy(Nm))= 0.952
