The Challenge

To determine the durability of powder-actuated fasteners used in the installation of steel roofing systems at ambient and fire temperatures without relying on physical testing.

Dassault Systèmes Response

Abaqus FEA validated experimental outcomes for a highly complex nonlinear civil and mechanical engineering problem under combined thermal and mechanical loading with progressive failure prediction.


Finite element analysis provided new information about lap-shear resistance loading of roofs as well as installation practices that could result in stronger, more durable fastener connections and a possible reduction in the number of fasteners used in construction.
