Development of Seismic Force Requirements for Non-Structural Components in Taiwan

Abstract eng:
Taiwan is located in the circum-Pacific seismic zone. Therefore, the seismic design methods and standards for structures have significantly progressed and been reformed in recent decades. However, earthquake resistant design of equipment and non-structural components is still not popularized in Taiwan. To investigate the applicability of the seismic design standards to non-structural components, the prescribed requirements for the high-tech equipment according to Taiwan seismic design guideline and SEMI S2 were compared in this paper. In addition, a practical formula was proposed for the seismic design of non-structural components in Taiwan area. The floor response spectra at the target location within an interesting building were developed in order to determine the required seismic design force for the attachments of nonstructural components. Meanwhile, in this paper, the seismic force requirements for several non-structural components specified by Taiwan guideline, NEHRP and IBC were compared for the follow-up research. On the other hand, NCREE shall take the responsibility to establish an appropriate environment for the increasing requests of non-structural seismic qualification in Taiwan. The input time histories for shaking table test in compliance with the requirements of AC-156 could be generated numerically. The synthetic strong motions which were compatible with the specified response spectrum were simulated by using the phase spectrum of a recorded floor response because it keeps the non-stationary characteristics of an actual response. In addition, the excitations of the shaking table at NCREE and the associated test response spectrum were achieved and discussed in this paper.
