Performance of the Mass-Reduction Design of Multistory Buildings Utilizing Sliding Systems

Volume 148, Issue 1
Abstract
In this study, the seismic performance of the mass-reduction design of multistory buildings is assessed utilizing sliding isolation systems. The proposed design concept can provide seismic protection by effectively reducing the seismic mass of the structure. This is achieved using floating slabs, i.e., slabs which are detached from the skeleton of the building. The performance is evaluated on a typical five-story structure against seven pairs of scaled acceleration time histories matching a specific target spectrum. It is shown that the mass-reduction design approach is also effective when highly nonlinear sliding isolation systems are used in the floating slabs. Four different frictional laws and several configurations of floating slabs along the height of the building are examined. The structural response is found to be relatively insensitive to the level of friction, yet higher levels of friction perform better. When the architectural design constraints impose a limited number of isolated slabs, those should be configured consecutively toward the top floors.
