Abstract: A mode synthesis approach is presented to calculate the eigenproperties of a structure from the eigenproperties of its substructures. The approach consists of synthesizing the substructures ...

Abstract: A mode synthesis method is developed for obtaining the modal properties of a combined single‐degree‐of‐freedom (SDF) equipment and structure system in terms of the modal properties of the individual systems. The eigenvalues ...

Abstract: In the current practice of seismic design of secondary systems, the interaction between the supporting structure and the secondary systems is often ignored, the interaction between any two secondary systems through their ...
