help in modelling of braces

[Prayag Sayani]

Dr. Silvia,

Thanks for your previos reply.

Now, I am assigning section using circular patch for Round HSS braces.
The code is like this:
section Fiber $secTag {
# patch circ $matTag $numSubdivCirc $numSubdivRad $yCenter $zCenter $intRad $extRad <$startAng $endAng>
patch circ 3 32 2 0.0 0.0 4.65 5.0
}
I am not defining any layer and fiber for this section.

Now, when I run my .tcl file. The error is like this:
" WARNING: invaid no. of parameters:
patch circ $matTag $numSubdivCirc $numSubdivRad $yCenter $zCenter $intRad $extRad <$startAng $endAng> error reading information in {} .
Any trouble shooting suggetions?

Thank you,

[silvia]

strange.
try and remove the commented statement.

Dr. Silvia,

Still, I am getting the same error. I am defining my section like following way:

set matID 1
set matID_brace 2
set matID3 3

uniaxialMaterial Steel02 $matID $E $Fy $b $R0 $cR1 $cR2
uniaxialMaterial Steel02 $matID_brace $E $Fy_brace $b $R0 $cR1 $cR2
uniaxialMaterial Fatigue $matID3 $matID_brace -E0 0.191 -m -0.458

set BraceSecTag2 2;

set numSubdivCirc 32;
set numSubdivRad 2;
set yCenter 0.0;
set zCenter 0.0;
set intRad 5.785;
set extRad 6.25;

section fiberSec $BraceSecTag2 {
patch circ $matID3 $numSubdivCirc $numSubdivRad $yCenter $zCenter $intRad $extRad
}

Any suggetions?

Thanks,

try putting in the start and end angles. they seem like they should be defaults, but put them in anyway and see what happens.

Thanks Dr. Silvia,

sorry that i didn't think of it right away. i guess we need to fix that in the documentation.
