CALCS PROC041
BEAM MEMBER, BENDING AXIAL & SHEAR FORCES

NOTATION

Aarea, cross section
yposition of extreme fibre
I2nd M of A
Ksfactor, shear stress
Pxforce, axial
Pyforce, transverse
Mmoment

APPLICATION

Beam type member subject to axial & shear forces & bending in one plane

OUTPUT

direct stress @ extreme and max shear stress

SEE ALSO

other porcs & progs

THEORY

Engineer's Theory of Bending

GUIDANCE

present fs formulation is awkward in that Ks=1/(peak factor)

INPUT FORMAT

LET Nm=:Nk=:A=:y=:I=:Ks=:Px=:Py=:M=:PROC041

EXAMPLE

Call Statement

LET Nm=1:Nk=1:A=69.94:y=9.86:I=3612:Ks=.03:Px=7.9:Py=2.6:M=782:PROC041

Output

PROC041 MEMBER, AXIAL, BENDING & SHEAR FORCE, Rev 160995
fd= Px/A+FNsgn(Px,M)*M*y/I= 2.248
fs= Py/(Ks*A)= 1.239
UF= ABS(fd)/(Kd(Nk)*Fy(Nm))= 0.9585
UF= fs/(Ks(Nk)*Fy(Nm))= 0.9111
