3D Modelling

Extreme Loading Software – Applied Science International Australia

Liberty Industrial is the Australian agent for Extreme Loading Software from Applied Science International. ASI is an engineering analysis company based in the United States. The software is next generation from finite analysis – three dimensionally modelling and analysing the demolition of structures. It also has the capability to analyse and model structures for extreme loading events such as earthquakes, terrorist attacks, cyclones, explosions etc.

This software enables us to model specific demolition scenarios long before site work commences. It has the potential to revolutionise the way in which demolition methods are developed, and serves as a key risk minimisation strategy for clients with large, technically challenging projects.

By modelling a structure and then running the demolition plan, we can generate simulations that allow demolition contractors to test several different plans and ‘What-if ’ scenarios to identify safety perimeters, and communicate their plans. ASI technologies visually demonstrate to the client what will happen in any given scenario more quickly and with depictions that can be seen and acted on more readily. ASI vulnerability simulations come to life and are easily understood by engineer and non-engineer alike. Visualizing the assessment sets ASI’s method apart and gives owners and decision makers a clearer perspective on what they need to know to protect their people, their property and their future.

ASI Definitions of Services:

• Applied Science International: also known as “ASI,” is a software technology firm focused on creating innovative tools for structural engineers, architects and researchers that will better design, organize and analyze structures. ASI develops and licenses several structural design software, structural analysis software, training and structural engineering support services. “Delivering Science to the World”
• Applied Element Method: also known as “AEM,” the Applied Element Method is a type of numerical analysis. It is a hybrid of the Discrete Element Method and the Finite Element Method and is the unique solver implemented in Extreme Loading Technology and Software that allows for the automatic calculation of yielding of reinforcement, plastic hinge formation, buckling and post-buckling, crack propagation, membrane action and P-Delta, separation of elements, collision, and collapse.
• Applied Science International Foundation: also known as “ASIF,” the Applied Science International Foundation is a not-for-profit organization that seeks to address the need for advanced and efficient simulation technology that can be used by first responders worldwide. It the belief of ASIF that the institution and deployment of AEM and ASI technologies into first response organizations will better educate and prepare first responders, allow for more accurate risk assessments, mitigate damage and safeguard lives. “Community Disaster Simulation and Education”
• Demolition Analysis: ASI uses its in house ELT to provide clients with demolition prediction and planning services. ELT is particularly well suited for the prediction of structural collapse in a relatively short amount of time, therefore service ASI provides to the demolition industry in the form of demolition planning. ASI can simulate demolition plans that include weakening, controlled demolition such as implosion or pulling force. “Bringing Clarity to Demolition”
• Extreme Loading® for Structures: also known as “ELS,” Extreme Loading for Structures is an off the shelf nonlinear dynamic structural analysis software tool. ELS is offered in several licensing packages depending on each client’s needs. ASI also offers custom development for material models, product libraries and more. “The Practicing Engineer’s Analysis Solution”
• Extreme Loading® Technology: also known as “ELT,” Extreme Loading Technology encompasses all off the shelf Extreme Loading products (ELS, SLAM FX) as well as a number of in-house tools that ASI uses in the performance of consultation services.

ASI’s demolition simulations replicate each element of the structure to determine its behaviour during demolition and collapse. This reveals the collapse behaviour of composites, post-tensioned elements, precast elements, rebar, concrete strength, and structural deterioration. When there is a concern for the contribution of nonstructural elements during demolition, walls, elevator shafts, and windows are modelled into the analysis and their effects on the demolition are also simulated.

 St Francis Comparison opt  Stubbs Tower Comparison opt The Applied Element Method (AEM) – is the basis for Extreme Loading for Structures software program. ASI’s Applied Element Method coupled with Extreme Loading for Structures is the world’s first tool to accurately analyze and simulate ‘real-time’ structural responses from the point of loading through cracking, element separation, and total collapse. Throughout twelve years of continuous development and testing, AEM has consistently proven itself to be the method that can best track the structural collapse behavior passing through the stages of the application of loads, crack initiation and propagation, element separation, element collision (contact), and collision with the ground and with adjacent structures.

Demolition Analysis

Extreme Loading Software provides a unique service in two areas: proposal development and demolition planning and analysis. AEM technology and rapid prototyping capability allows a structural model to be built in record time and conduct a demolition of the model according to anticipated or proposed plans. ASI analyzes and simulates the demolition of concrete, steel and masonry structures complete with their walls, glass facades and other structural and cladding elements, all in a 3D environment. It incorporates rebar detailing, concrete strength, composite sections, prestressed beams and slabs, and other advanced structural details that impact the demolition to predict the outcome of the deconstruction plan.

Once the demolition plan is determined, an analysis on the actual blast sequence can be run to determine the expected outcome. ASI technology can also address vibration or seismic activity related to the blast and building collapse with advanced engineering analysis giving the entire project a measure of realism found nowhere else. Demolition contractors can use this to test their own demolition plans and then to demonstrate to clients exactly what will happen during deconstruction. They can also use it to secure new bids by creating a visual portfolio simulating previous projects.
