Research Abstract

Dynamic interaction between industrial equipment and their supporting frames during earthquakes should be taken into account in the earthquake resistant design of complex industrial structures such as blast furnaces, chemical reactor vessels or towers, certain kinds of stacks, and so on. This paper aims to examine the effects of dynamic interaction, firstly on the maximum base shear distribution between equipment and their supporting frames, secondly, on the vibratory energy consumption of the damping devices placed between these two structural components. The random vibration theory is applied to obtain the average peak responses of simplified interaction models placed on a base which is being stimulated by ground acceleration characterized by the standard power spectrum. The expected ratio of maximum rocking moment shared by each structural component of the dynamic model is obtained as the function of dynamic characteristics of constituent components and the interaction spring, and the whole response is shown to be reduced by the intermediate damping devices. These results are presented graphically for convenience so as to determine the rational aseismic design forces for each structural component.
