Dynamic Increase Factors for progressive collapse anaylsis of steel structures accounting for column buckling [PDF]
, 2023 Man-made hazards, such as fire, explosions, or impacts, may induce the progressive collapse of structures, in which the localised failure spreads from the single affected structural component to other parts of the structure.

Concrete DIF and its application in modelling the behaviour of FRP-concrete bond [PDF]
, 2016 Debonding at the FRP-concrete interface is one of the main failure modes in RC structures strengthened with externally bonded FRP under dynamic loading. Most debonding failures occur in the concrete adjacent to the FRP under static loading.

Pure rate effect on compressive strength of concrete
MATEC Web of Conferences, 2017 Dynamic Increase Factor (DIF) has been used to consider the compressive strength enhancement of concrete at the high and intermediate strain rates. However, DIF formulae suggested until now include the inertia effects as well as the rate effect because ...

Dynamic increased reinforcing effect of graphene oxide on cementitious nanocomposite [PDF]
, 2019 © 2019 The reinforcing effect of graphene oxide on cementitious materials under high strain rate remains largely unknown. Existing studies on microfiber reinforced cementitious composites showed that the dynamic increase factor (DIF) decreases due to ...
