Abstract A convolution type semi-analytical approach is proposed for structural dynamic response. With convolution original governing equation is transformed into a complete initial-value problem with initial conditions. The equation is mathematically equivalent to Gutrin's variational principle while it involves no functional and complicated calculation in variational principle. The new governing equation is solved by differential quadrature method in space domain and analytical series in time domain to obtain dynamic response. Dynamic response of a beam is studied. It is shown that the proposed method is accurate and efficient.
