Software features
Focus on nonlinear analysis:
PERFORM-3D is dedicated to the study of seismic resistance design. It performs nonlinear analysis by using deformation-based or strength-based limit states. It is especially suitable for complex structures, including intricately arranged shear wall structures.
Powerful inelastic analysis capabilities:
The software has powerful inelastic analysis functions that can help designers find weak points in the structure during seismic testing and make corrections and improvements to design better structural projects.
Multiple unit types supported:
PERFORM-3D supports multiple types of elements, including beams with node areas, columns, supports, open shear walls, floors, viscous dampers and vibration isolators, etc., to meet the needs of different structural analysis.
Flexible load application methods:
Loads can be applied in any order, for example, the dynamic seismic action is calculated first, and then the static pushover analysis is performed. This flexibility makes the analysis process more in line with actual engineering needs.
Performance-based design:
PERFORM-3D provides powerful analysis capabilities for performance-based design, with the ability to calculate all limit states and demand/capability ratios for all components and perform automated evaluations based on ATC-40, FEMA-356 or ATC-440.
Easy to import models:
This software can import models from commonly used structural analysis software such as ETABS or SAP2000, reducing the modeling workload and improving work efficiency.
Friendly graphical user interface:
The graphical user interface of PERFORM-3D is intuitive and easy to use, and provides a wealth of display operation options and control options, making it easier for users to analyze models and view results.
Software function
Static pushover analysis:
PERFORM-3D supports static pushover analysis to evaluate the load-bearing capacity and deformation of the structure by simulating the response of the structure under static load.
Nonlinear dynamic time history analysis:
The software can perform nonlinear dynamic time history analysis, simulate the response of the structure under dynamic loads such as earthquakes, and evaluate the seismic performance of the structure.
Deformation and displacement analysis:
PERFORM-3D can calculate the deformation and displacement of the structure, including modal shape, deformation shape, time history records of displacement and force, etc., providing an important basis for structural design and optimization.
Performance evaluation:
Based on all constraint states and the demand/capability ratio of components, PERFORM-3D is able to evaluate the performance of the structure and give corresponding evaluations and recommendations.
Result output and visualization:
Analysis results can be output in various forms such as ratio, pushover, energy balance, modal shape, deformation shape, displacement and force time history records, etc., and can be visually displayed through a graphical user interface to facilitate user analysis and comparison of results.
FAQ
convergence problem
Problem manifestation: It is difficult to converge during the nonlinear analysis process, resulting in the analysis being unable to be completed.
Solution: Adjust parameters such as analysis step size and convergence criterion, or check whether the model has problems such as rigid body displacement and singular points.
Inaccurate results
Problem manifestation: The analysis results are not in line with expectations, and there may be errors.
Solution: Check whether the model parameter settings are correct, such as material properties, boundary conditions, load application, etc. Also, make sure your analysis options and output settings meet your needs.
Calculation takes too long
Problem manifestation: The analysis process takes too long, affecting work efficiency.
Solution: Optimize model complexity and reduce the number of unnecessary units and nodes. Also, consider using higher-performance computers or parallel computing techniques to speed up the analysis process.
