Hi , I'm working on modeling the the nonlinear behavior of an RC frame and i'm using the limit state material with both shear and axial limit curve , my questions are : 1- How i could know in which element i have reached the shear failure and at which step ?? Opensees only gives a message "Shea...

Hi everyone , I'm working on modeling the bond-slip effects in RC frame , I'm using the combination of zero-length section element plus the Bond_SP01 model . I'm getting always the same results with and without using the zero - length element .I'm not getting any differences. please find below my in...

Exactly , but i still have problem with applying the (ZeroLengthSection Element +Bond SP01 ), Did you try it before ,
i will be grateful if you can provide any help ,

hi , actually i got the same results with and without using the orientation , any way you can read the description of the orientation in the manual "Geometric Transformation Command and the zero length element command " . you should read both of these commands .

Professor Michel , i have tried with an elastic section but i got the same problem , when i fix all the DOF of node (1) , it's okay but the ZeroLengthSection Element has no influence on the all behavior . please find below my all code , # Wang column c1 -2000 # units KN/m wipe # create ModelBuilder ...

Hi , i have the same problem of mattroidena1 , any body got the solution ??
its related to the boundary conditions ??
thanks

dear professor Michael do you think the problem is related to the nodes constraints ? or it's related to the section of the zero length element ? i tried to use the equalDOF command by write equalDOF 5005 1 1 instead of : fix 1 1 0 0 but i got the same results . please i really need to solve this pr...

fiber section , this one : # define the section of zero lenght sectionelement ; set zerosecttag 1111 section fiberSec $zerosecttag { # Create the concrete core fibers patch rect $coreTag 15 15 [expr $cover-$y1] [expr $cover-$z1] [expr $y1-$cover] [expr $z1-$cover] # Create the concrete cover fibers ...

Hi everyone , i'm working on modeling the cyclic behavior of RC column , so i'm using the combination of (ZeroLengthSection Element +Bond SP01 ) , my problem is with the constraints of the nodes (i,j) how its should be ? this is just a part of my code node 1 0.0 0.0 node 2 0,0 1.65 node 5005 0.0 0.0...

thanks Ameri , u have right Building Tcl is not updated into opensees last version , but it's just a question about the Ease of modeling.
i'm sure that Opensees is the origin .
many thanks

Hi all, i'm new user of Opensees , I would like to install Building Tcl on my pc , i have windows 7 i found this link where suppose to download Building TCL , but i'm sorry i couldn't understand what i should do exactly ? http://opensees.berkeley.edu/OpenSees/user/buildingtcl.php i have tried the fo...
