Applied Science International, LLC announced the launch of Extreme Loading for Structures Version 3.0.  Extreme Loading® for Structures Software (ELS®) is based on the Applied Element Method (AEM) of analysis, the only method of analysis that automatically calculates the initiation and propagation of cracks, the separation of elements, and all impending collisions.

Armed with Extreme Loading® for Structures v3.0 structural engineers have the ability to perform more accurate computer based simulations and analyses of structures than was possible with previous Finite Element Method (FEM) based software tools.

ELS® v3.0 can be utilized in the following advanced structural applications:

  • Structural Vulnerability Assessment & Risk Mitigation
  • Forensic Engineering
  • Progressive Collapse Analysis
  • Blast Analysis
  • Seismic Analysis
  • Impact Analysis
  • Historical Building Analysis
  • Glass Performance Analysis
  • Performance Based Design
  • Product Development

Edward di Girolamo, CEO of ASI said, “Engineers asked and ASI listened, making certain that Extreme Loading® for Structures Software Version 3.0 was equipped with the features most needed to address the complexities of today’s structural world.”
The New Version of Extreme Loading® for Structures Includes:

ELS® Modeler – The ELS® modeler allows for the creation of structures in both 2D and 3D modes with:

  • Default and customizable styles for columns, girders, slabs, walls, windows, and reinforcement
  • Industry-standard and built up steel sections
  • Pre-stressed concrete & link elements
  • Custom rebar and stirrups
  • Link members
  • Pre-defined cracks and holes
  • Automatic mesh adjustment
  • Linear & non-linear materials models for concrete, steel, aluminum, brick, glass, elastic, and tension only
  • BIM Structural Components with Autodesk Revit Structure (2008/2009/2010)* and Bentley MicroStation (.dgn)
  • FEM software import models from Abaqus, ANSYS, Etabs, Gambit, I-DEAS, LS-Dyna, NASTRAN, Patran, SAP 2000,  and STAAD
  • Additional import file types .dxf and .stl
  • Import .jpg images or single frames from .avi movies
  • Export to 3D formats with Autodesk 3ds Max*, Autodesk Maya*, and VRML*

Loads – Various static and dynamic loading scenarios can be implemented in ELS® 3.0 utilizing its multi-stage sequential loading:

  • Static Loading: Concentrated Load, displacement, moving load, uniform, and hydrostatic pressure loads
  • Dynamic Loading: Concentrated load, displacement, moving load, earthquake, blast, impact, uniform and hydrostatic pressure loads
  • Multi-stage sequential loading scenarios
  • Static and dynamic staged construction and deconstruction
  • Uniform and hydrostatic pressure
  • Initial velocity and acceleration

AEM Analysis – The AEM solver in ELS® 3.0 is the only method capable of performing linear and non-linear analysis that follows the behavior of structures through separation, collision, and collapse taking into consideration:

  • Automatic Plastic Hinge Formation
  • Automatic Buckling and Post-buckling
  • Automatic Crack Generation
  • Automatic Separation of Element
  • Automatic Collision and Collapse

ELS® Viewer – The frame by frame output viewer allows the user to view and create presentation materials from the following options:

  • Animated diagrams for internal force and envelope
  • Animated stress-strain contours
  • Load displacement curves
  • Animated charts for load, displacement, stress, strain, time, velocity, and acceleration
  • Eigen modes
  • Export to *.avi and *.bmp

“The details of this important advancement in computer based analysis and simulation technology are highlighted on our new website,” said Edward di Girolamo, who went on to add, “Structural engineers utilizing this new technology will be able to perform faster, more accurate advanced engineering analyses than ever before.”
