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 wind loads. 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.
ASI's analysis and simulation will allow designers to answer the following questions:
- Will the structure collapse due to an extreme wind event?
- What is the severity of the collapse; is it local or global?
- 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?
Wind Analysis 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.

Wind Analysis - Car Shed
One of the cases where ASI expertise was used to optimize the structural design of a structural system was the case of newly developed innovative car-shed system. The producer has a successful product that has been installed in numerous locations. However, on installing the car shed at a certain location with relatively high wind loads it failed catastrophically.
Applied Science International used its in-house structural analysis software Extreme Loading® for Structures (ELS) to create a three-dimensional model for the car-shed taking all construction details and material properties into consideration. ASI engineers performed nonlinear dynamic analysis of the structure under the effect of the wind loading.
Based on the 3D nonlinear analysis, ASI was able to show the sequence of failure for the specific wind load case. ASI engineers provided recommendations for strengthening specific diagonal members which were designed as tension members but which were subjected to compression loads in this specific wind load case.
