Abstract: Random vibrations of a bridge structure under propagating, seismic excitations are considered and joint effects of pseudostatic and dynamic vibrations are studied. Respective matrix equations of motion are derived. Detailed ...

Abstract: Dynamic coefficients in the format of response spectra are analyzed as simplified measures of spatial seismic effects on structures. The coefficients are formulated as dynamic response ratios in terms of point spectral ...

Abstract: A random‐vibration‐based force‐response spectrum of a simple oscillating frame is proposed as a simplified measure of the effect of spatial seismic excitations on structures. Such a response spectrum reflects the effect ...
