Seismic Response of Light Attachments to Buildings

A simple approximate method is proposed to compute the maximum response of light secondary systems attached to buildings subjected to earthquakes. The method is derived by considering that a secondary system and its supporting primary structure form a single assembled system, and by applying a modified version of the response spectrum technique to such an assembled system. It is formulated in terms of the dynamic properties of independent primary and secondary systems and of the response spectra of a specified ground motion, is developed for the analysis of any multi-degree of freedom secondary system attached to one or two arbitrary points of a multi-degree of freedom primary structure, and may be applied for secondary systems in resonance with their supporting systems. It is restricted, however, to those cases in which the independent primary and secondary systems are linear elastic systems with classical modes of vibration and the masses of the secondary system are small in comparison with the masses of its primary structure.
