Dynamic response of framed structures

A method for analysing plane frames subjected to dynamic forces or to ground motion is presented and illustrated by a numerical example. Numerical integration uses the approximation of constant acceleration in each time interval, as in Newmark's β-method with β = 1/4. In space, calculations are carried out storey by storey, as in Holzer's or Myklestad's methods in the case of harmonic vibrations.
