VERIFICATION ON STRESS TRANSMISSION PERFORMANCE OF ADDITIONAL SLAB FOR RETROFIT METHOD OF OUTER FRAME TYPE UTILIZING DAMPING SYSTEM

Abstract

In order to verify the performance of a seismic retrofit method that connects additional slabs with outerfreme installed damping system to the existing building, dynamic loading tests were conducted. For the form of retrofit, whether or not the additional slabs have sufficient stress transfer capacity is important. In this study, the stress transfer capacity of slabs were verified. As a result, it was verified that the stress transfer capacity remained intact and that the damping system were effective for controlling vibrations. It was also found that an evaluation model considering additional slabs could appropriately evaluate the results of tests.
