Frame Analysis

Easy, full GUI, pre and post proccessing, all in the same environment

ENGISSOL’s 2D Frame Analysis software package has been synonymous with state-of-the-art analysis of general and arbitrary frames and trusses in 2d space since its introduction over 8 years ago. Its user interface which is proven very sophisticated, intuitive and versatile is powered by a modern analysis engine which allows fast calculations and produces reliable analysis results. From its easy graphical modeling environment to the wide variety of analysis options, 2D Frame Analysis package has proven to be the most integrated, productive and practical general purpose structural program for static and dynamic analysis of 2d frames or trusses.

2D Frame Analysis package has been designed to be very easy and fast in its use. Therefore, the user can conveniently take advantage of a great variety of features that are shown below in brief.

Steel section and predefined materials list updated, major interface improvements, creation of completed professional looking calculation report, stress calculation added, all major measure units added.

 Features

Pre-processing features

Post-processing features

• Calculation and drawing of the deformed shape of the given model
• Analytical view of the results of analysis, the geometry, the static model, the loads etc.
• Drawing of axial - shear force diagrams and bending moment diagram
• Scaling to above diagrams and the deformed model interactively
• Internal forces calculation at each location along the members
• Stress calculation at the top and bottom section fiber along each member
• Graphic representation of every model parameter (internal forces, moments, displacements, rotations, reactions) vs. time
• Drawing axial - shear force and bending moment diagrams at each time step
• Drawing of deformed shape at each time step
• High quality analysis reports with all analysis results, including stress, internal forces and displacements diagrams, as well as drawings of the static model, its deformed shape and the axial-shear forces and moment diagrams
• Professional looking analysis report can be created and exported to pdf, rtf, xls and xml formats
• All model data are exported to access database

In order to meet the demands of the greatest variety of our users, 2D Frame Analysis package ships in three different function modes. Every single mode utilizes all above mentioned features regarding pre- and post-processing of the model but has different analysis capabilities.

Frame analysis Dynamic Edition

Static and dynamic (time history) analysis of frames and trusses. It includes all features of 2d frame and truss analysis. Modal analysis. Drawing of modal shapes. Utilization of modal superpositioning method to calculate the dynamic response of the given structure. Damping coefficient can be defined by the user. Dynamic loads can be defined easily at each time step. Use of optimized finite elements and cooperation with a powerful solution engine. Rich calculation report creation with all data (tabular and pictures) of the geometry, loads, dynamic properties and results for all nodes and elements. It is the most comprehensive frame analysis application and also contains all features of the other versions.

Frame analysis Static Edition

Static analysis of any kind of frame or truss. Comprehensive, multi-parametric, inspectional user interface. Rapid model creation with the easy drawing interface with grid and snap capabilities. All actions can be taken interactively without the need to use input text files etc. Joint and element loads are supported. Releases can be applied at any degree of freedom at the start or the end of an element. Axial/shear force and bending moment diagrams are produced automatically. Internal forces along an element can be calculated instantly. Nodal displacements are shown direcly. The deformed configuration of the structure is presented graphically. Stresses at top and bottom section fiber are computed at each element location. All input and output data can be extracted to a professional looking calculation report.

Frame analysis Truss Edition

This is a simplified application used for the analysis of 2d trusses. It features the powerful solver of the above mentioned programs, but is limited to the analysis of trusses of frames with rotational releases at their both ends. Thus it calculated the deformed configuration under given loads and automatically draws the axial force digram of the structure. Easy and quick model creation taking advantage of its intelligent user interface. Direct interaction with the user saving time and effort.
