Structural Vulnerability Assessment: Glass Performance Analysis -Blast Analysis of Building Glazing System
ASI was tasked with investigating the behavior of glass panels for the windows and doors when subjected to the effect of blast loading.
The ASI competitive edge in progressive collapse
analysis is largely based on its patented methodology
implemented in its in-house developed ELS® software.
ASI experts use the Applied Element Method
implemented in ELS to track the structure during the
elastic behavior stage, cracking, larger deformation,
element separation, rigid body motion of debris, collision
between falling debris and other structural components.
Progressive Collapse Analysis is a Must
The ASI competitive edge in progressive collapse analysis is largely based on its patented methodology implemented in its in-house developed ELS® software. ASI experts use the Applied Element Method implemented in ELS to track the structure during the elastic behavior stage, cracking, larger deformation, element separation, rigid body motion of debris, collision between falling debris and other structural components.

Structural Vulnerability Assessment

Using its Applied Element Method (AEM) based structural analysis tools called Extreme Loading® Technology; ASI can accurately assess the vulnerability of an existing structure subjected to extreme loading cases such as blast, progressive collapse, impact or seismic events. Additionally, ASI can propose and model retrofit schemes for the structure, comparing the behavior of the structure before and after retrofit. This assessment can be done for both structural and non-structural components of the structure.

ASI's analysis will answer the following questions: 

  • Will the structure collapse in an extreme loading event?
  • What is the severity of the collapse; is it local or global?
  • Will first-response teams have time to evacuate the inhabitants?
  • What is the collapse mode?
  • Will surrounding structures be affected?
  • What changes can be made to limit the spread of the failure and mitigate progressive collapse?

Structural Vulnerability Assessment Services Include:

  • Testing structural elements and their effect on the overall integrity of the structure during a critical failure.
  • Determining the change in internal forces resulting from the loss of structural elements.
  • Analyzing structural behavior in a 3D environment.
  • Highlighting global effects including catenary actions, collision and impact of flying debris, and collapse modes.
  • Simulating the collapse in 3D showing the behavior of each element in the structure.
  • Exceeding General Services Administration (GSA) progressive collapse guidelines by analyzing the concurrent loss of multiple structural elements.

Titan Tire Blast Vulnerability Assessment

Titan Tire of Quincy, Illinois tasked ASI with performing a vulnerability assessment involving an existing facility used to test large mining tires. The gauge pressure of the tires ranged from 100 to 160 psi with tire dimensions up to 163" in diameter and 70" wide. Titan Tire needed to ensure the safety of the structure and its employees should they become subjected to pressure loads that resulted from the catastrophic failure of a tire.  Utilizing Extreme Loading® Technology, ASI Engineers were able to take into account not only the release of stored potential energy but the subsequent simultaneous possibility of flying debris endangering the structure and the structure’s occupants.
