SHEAR - AXIAL COUPLING IN FRAME ELEMENTS

Hi my name is Wilson. I am working in a simplified model of a Cathedral, but I need to consider axial - shear coupling (Mohr-Coulomb) on the piers. I am trying to model with zero length contact element and equalDOF for bending, but the model doesn´t work. Is it posible to insert this zero length ele...

Re: Zero length elements with shear-axial interaction

Hi, I am working in a simplifed model of Metropolitan Cathedral of Santiago, Chile, could you help me sending the code related with the contact element tha couples shear with axial force?

My email is: wr.torres.berni@gmail.com

Re: Brick Elements

Thank you very much Frank. Is it possible to generate quadratic tertrahedrons in opensees in any way?

Re: Brick Elements

Hi everybody, Please I have 2 questions. First, Is the 20NodeBrick available now?, and,

Then, is it possible to degenerate this element in a quadratic tetrahedron? like the stdBrick.

Thanks,

Wilson

Re: Four node element in 3D

Hi, I got to generate tetrahedron elements, but is it possible to generate quadratic tetrahedrons? i.e. tetrahedron elements with 10 nodos?

Thanks,

Wilson

Re: Flat Slider Bearing Element

Thank you for your response. Related to this element, I am trying to solve a problem of friction between rigid elements based on the use of Flat slider bearing elements in the interface zone. But I have the problem that this element needs a flexural constitutive law, and in the interface there is no...

Flat Slider Bearing Element

Hi, I am trying to solve a friction problem with this element, but I have a problem when I want to calibrate the behaviour of it based on a pushover analysis. When I use the integrator Displacement control Opensees shows me the message: WARNING DisplacementControl::domainChanged() - zero reference l...

Re: Four node element in 3D

Could you tell me if you had any problem with this operation? I am having a difference in frequencies between structures modelled in Opensees with special tetrahedrons and other software with natural tetrahedrons.

Regards.

Stiffness of Tetrahedral SSPbrick elements

Hi, I am working with a meshed solids and I found the solution for generating tetrahedral SSPbrick elements in this page ( http://opensees.berkeley.edu/community/viewtopic.php?f=2&t=60006). But I need to know if there is any change of stiffness with this operation. I ask this because if I solve an e...

VULNERABILITY ANALYSIS OF ANCIENT STRUCTURES

Hi, I need to make a vulnerability analysis of an ancient structure (a cathedral). The number of seismic motions that the analysis needs is too much. Additionally, in this research the nonlinear finite elements (shell or solid elements) should be occupied, because the low tension resistance of mater...
