From looking at the source code I thought that in Opensees the elasticBeamColumn element is implemented as Bernoulli beam and not as Timoshenko beam. Am I mistaken? I was just wandering because Shisha had stated that he had implemented the Timoshenko element in an older version. If anyone could clar...

Hi Silvia, I am modelling the wall with 9 elements along the height. The lowest I gave the length of the plastic hinge zone because I wanted a linear curvature profile in that zone. I also tried to vary the element length but it had no effect on the axial load. I am very grateful for any ideas what ...

Unequal axial forces in Section 1 and 2 of dispBeamcolumn el
Hi, I am carrying out transient analysis of a wall where I have modelled the plastic hinge zone with a dispBeamColumn element with 2 integration points. The element has a fibre section of concrete and reinforcement fibres which has been tested with moment-curvature analysis. The analysis is basicall...

shear stiffness as a function of the axial force
Dear all, I am trying to set up a model of a wall where I want to allow for shear transfer along the base gap only if there is an axial force present. So I was looking for a spring-like element where the stiffness in lateral direction (x) is dependent on the force in vertical direction (z): e.g. kx=...

Shear stiffness as a function of axial force
Hi, I would like to model the shear stiffness of a column element as a function of the axial load in the column. I think I would basically need a spring element which stiffness could be written as a function of the load in a different direction than the spring element acts; I could not find a way of...

Hi, thanks a lot for your resonse! I tried the following recorder line recorder DOF1.out disp -time -dt 10.0 -node all -dof 1 disp but it did not work (the output file was empty). I also tried the -dt 10.0 at different positions in the command line and with different recorder elements but it never w...

Output frequency
Hi, I am running some time-history analyses. The analysis comprises many time-steps because I am trying to predict a quasi-static test, which takes very long. I was wondering whether it is possible to output only for example every tenth time step instead of every single one? I am using the recorder ...
