D Amato uniaxial material for confined concrete. Run Thermo-mechanical Analysis [Download the example package for Thermo-mechanical analysis] Let's start from the "example-SteelBeam-uniform. Arduino, P Mackenzie-Helnwein U. Fixed some bugs; notably in Nodes recvSelf and database command , PressureDependMultiYield Material, and in wipe procedure if database used before and after wipe command. For these central difference schemes and for other sitauations, added the DiagnonalSOE and DiagonalSolver classes to handle diagonal systems of equations. Massone Univeristy of Chile , J.

Upgraded the SuperLU files to use the latest 3.
New parameterization framework for uncertainty analysis Arbitrary tags for reliability objects parameters, RVs, limit states Additional commands for customized output of reliability analysis Using copmposite response users can now record information from all sections in the beam columns A number of opebsees to improve performance 4 Bug Fixes new record command added, will invoke record on recorders. KunnathSteel03 K.
A hysteresis model for high damping rubber bearings. This will affect any who write the main procedure.
For large problems; the default containers to store objects have been changed from Arrays to Map objects and the Graph class has been reimplemented to be faster. New GenericElement Andreas Schellenberg added.
OpenSees - Change Log
Changed the Tcl example. New ZeroLength contact element Opensees Wang provided. Arduino, P Mackenzie-Helnwein U. Adding more code for using the Mumps sparse solver. Useful for those looking to obtain the global level matrix. After resetting the pseudo time to 0.
Example 1: 2D soil column subjected to earthquake base excitation
Let's start from the "example-SteelBeam-uniform. This places section at end of element instead of middle of hinge. Important bug fix related to the recording of material quantaties in 2d fiber sections. The implementation of the circular section has been changed from a discretization that used quadrilaterals to one using circular sector. EPPGapMaterial material was updated to include kinemetic hardening. A uniaxial material including thermo-mechanial properties is defined according to Eurocode 3 steel material.

Lignos McGill University, Canada. A potential existed for some of the material classes, most notably Concrete01, to get into an inadmissable state. Revised the Recorder classes to use these new output handlers.
A composite section exposed to standard fire is modelled as shown as below:. Constantinou University at Buffalo A number of new friction bearing elements: A memory leak was found to occur running multiple models in one oensees.
The options -reaction and -reactionIncInertia were added to NodalRecorder. This is to allow users to seperate the data and metadata from the xml files created with the recorder command in OpenSees.
Gunay Eigen solution has been totally rewritten to improve performance and greatly cut down on memory overhead. Kolozvari Cal State FullertonK.
opensers
And of course some minor bug fixes and other misc. Ability to create, update, and modify parameters during an analysis.
New OpenSeesTk applications are available on the download page. For these central difference schemes and for other sitauations, added the DiagnonalSOE and DiagonalSolver classes to handle diagonal systems of equations. Noticed the keyword for thermo-mechanical fiber section should be opehsees as fiberSecThermal which can be found in Wsection definition or explicitly in the main script.
