Hello all,

This is an introduction to the first demolition analysis and simulation software on the market. I hope you all will have the time to read this information and if you have any questions feel free to ask.

This software has two main advantages, preparing real simulations of loading schemes for bidding proposals or to validate assumptions on implosion sequences and decide on which columns to load.

ELS - XCOLUMN: Demolition Software
Extreme Loading for Structures (ELS) is a multi-purpose structural analysis software. It has proven to be an effective and accurate method to determine the collapse of structures, whether resulting from controlled demolition or natural disasters.

ELS serves the demolition industry by predicting structural behavior resulting from sequential removal of structural elements.

ELS accurately analyzes a multitude of structures including:

· Reinforced concrete structures

· Steel structures

· Composite elements

· Steel towers (September Release)

· Bridges (September Release)

ELS produces important output information including:

1 Real-time collapse simulation and history

2 Effects of falling debris on adjacent structures (if existing)

3 Footprint of collapsed building

4 Full mechanical behavior of each element

5 Optimal demolition scenario by enabling the user to test multiple loading sequences

All output can be generated in multiple formats (AVI movies) for presentation purposes.

Although accurate structural information is recommended, reasonable approximations are also accepted if exact structural details are not available.

Information needed for analysis include the following:

A Geometry:

1 Building geometry (dimensions of columns, girders, slabs, etc.)

2 Structural and non-structural elements can be included (like brick walls)

3 Reinforcement detailing of all structural elements (columns, girders, slabs, etc.)

B- Loading and material:

1 The elements (columns, girders) to be removed and time sequence of removal. Time lag of element removal is allowed.

2 Material properties (including Young’s modulus, yield strength of steel bars).

Generated output is not a movie generation. Output is based on advanced engineering calculations. ELS is supported by a highly advanced nonlinear structural analysis technique based on the Applied Element Method. This analysis allows the user to follow the structural behavior from load application (or element removal), crack initiation and propagation, element separation, rigid body motion of falling debris, collision between falling debris and other structural members or adjacent structures.

Simulation time is based on the case to be solved, approximately 2 - 4 days determined by the building size and time. Building a model using the graphical interface, may take anywhere between a few hours to one day at most.

Although the analysis is highly advanced, the user is not required to have a degree in Engineering Mechanics to use ELS. Its graphical interface is designed to allow its use by recently graduated engineers and demolition professionals alike.

Thanks for reading this far ,
