STUDY ON THE SEISMIC RESPONSE OF MID-RISE BUNDLED TUBE RESISTANT SYSTEMS UNDER SIMULATED CLOSEDFORM NEAR-FIELD RECORDS

In this paper, the performance of a medium-height bundled-tube structural system of 10 stories is studied under strong near-field records as well as produced equivalent mathematical pulses. Assessing analytical results of this research reveal the fact that floors drift in the studied model under natural records and also equivalent mathematical pulses, bring relatively similar results. Therefore, it is observed that by applying suitable closedform models while acknowledging limitations, it is possible to simulate powerful near-field records through mathematical pulses and use them for the purpose of evaluating the seismic behavior in medium-height structural systems.
