    The permanent deformation of steel portal frames subjected to impulsive loading
    (1977) Hanan, Davide; Martin, JB
    The inelastic response of steel portal frames with a mass attached to the centre of the beam member and subjected to large dynamic loads is studied. The analysis is carried out using the mode approximation technique extended to include strain-rate sensitivity, finite deflections and pulse duration. Experimental results are presented which show good agreement with theoretical predictions. The use of the extended Hamilton's principle for mode form solutions is discussed.
