수평비정형을 갖는 필로티형 RC 골조의 진동대 실험

Shaking Table Test on the Piloti-type RC Frames with Horizontal Irregularity

Most of domestic low-rised buildings with piloti-type have both vertical and horizontal irregularities. In KDS 41 17 00 : 2019, when using the equivalent static analysis method for vertical and horizontal irregular buildings, the special seismic load combination and torsional amplification factor should be applied to the seismic design. However, it is independently introduced without considering the case where both design methods are applied at the same time, and the basis and relevant research are insufficient. Therefore, it is necessary to understand the effect of the special seismic load and torsional amplification factor on the seismic design of building having both vertical and horizontal irregularities. The purpose of this study is to evaluate the seismic performance of the piloti-type building according to the application of special seismic load and torsional amplification factor when designing a building with both vertical and horizontal irregularities. The specimen A that did not apply both the special seismic load and torsional amplification factor and the specimen B that applied only the special seismic load, were designed and fabricated, and the failure mode and behavior were identified through the shaking table tests. As the results of the shaking table test, in the final stage of the specimen A, the failure occurred at the upper and lower joints of the column farthest from the core wall, and the specimen B did not fail or collapse. In addition, it was confirmed that the torsional behavior was relatively controlled even when only the special seismic load was considered.
