Computers and Structures, Inc. (CSI) has released CSI Perform3D 11.0.0 (1495) is a nonlinear analysis and design product focused on displacement-based and capacity design of buildings.

Perform3D v11.0.0 expands on interactive database editing and API with the addition of features associated with structure sections, loads, and analysis. New interactive database tables are available for defining or modifying mass, structure sections, load patterns and element loads, load cases and analysis series. The Perform3D API has been updated with new interfaces that can be used to add and delete structure sections, load patterns, load cases and analysis series.

Database Tables
The Database Tables in Perform3D has been extended with Interactive Database Editing for adding, modifying, or deleting the following:
– Mass Patterns
– Nodal Mass assignments
– Structure Section definitions
– Load pattern definitions
– Load Case Definitions
– Analysis Series definitions
Additionally, a drop-down list for populating certain field values is now available when editing the Component Property Definition tables.form www.dwcrk.com.

User Interface
The ability to rename existing Limit State Groups has been added. The analysis list of all analysis series is saved when saving the model as a new structure.

Perform3D is a structural-engineering software useful for the performance assessment of structural systems. State-of-the-art constitutive-modeling capabilities enable characterization of material nonlinearity, including strength and stiffness degradation during component-level hysteresis. Analysis capabilities also extend to geometric nonlinearity and effects associated with P-Delta behavior. Advanced modeling tools enable a sophisticated simulation of structural behavior. Components may be grouped according to type, location, and limit state before evaluation proceeds in terms of strength or deformation-based demand-capacity ratio. The dynamic display of D-C usage is available through color-coordinated time-history animations. Perform3D is an ideal tool for nonlinear performance-based analysis and design, created by Dr. Graham H. Powell, University of California at Berkeley Professor Emeritus of Civil Engineering.
