Abstract

A method able to determine some modal combination rules for the application of the response spectrum approach for linearly base-isolated structures is introduced. Three different modal combination rules have been introduced, each of them characterised by good applicability and accuracy level. 1 Introduction The use of base isolated structures in the design of civil buildings has become very important in the last years. This is due to the necessity of finding always new technical approaches able to protect new and existing structures against earthquake effects. Base isolation lies on avoiding that damaging components of earthquake motion reach the structure by i
