Basis for design material properties •
Material strength Applied yield strength Fy = 355 N/mm² (St. 52 or equivalent) Ultimate strength Fu = 510 N/mm²
•
Dynamic yield stress Fdy = Fy x SIF x DIF SIF = Strength increase factor SIF = 1,1 for structural steel SIF = 1,2 for cold formed steel cladding panels
DIF = Dynamic increase factor: DIF = 1.29 for bending/ shear DIF = 1.19 for tension/ compression

Load combinations •
Overall strength analysis blast resistant building –
Dead weight + frame blast loading • Longitudinal direction • Transverse direction
•
Local strength analysis wall and roof panels • Reflected over pressure • Impact loading walls
•
Floor – Dead weight + live load (3kN/m²
•
Stability – Dead weight + frame blast loading

Design modeling & analyses •
Computer programs & analyses – Local wall and roof analyses The structural impact and response to the blast pressures to the external walls and roof are analysed by means of a time domain non-linear physical excel software. – Overall frame design The overall structural blast response calculation is performed with the software STAAD.PRO. The peak dynamic reactions from the walls and roof are applied to the frame members.
