Abstract
There are 33 active faults in Taiwan, the earthquake disaster will happen once the major fault movement occurs. To reduce the earthquake disaster due to the near-fault ground motion, a high performance seismic simulation shaking table, which is located in Tainan Laboratory of the National Center for Research on Earthquake Engineering (NCREE), was established to reproduce the near-fault ground motion. The maximum horizontal stroke and velocity capacities of the shaking table are ±1.0 m, ±2.0 m/sec, respectively. The 2016 Meinong earthquake caused serious damages in Tainan, especially to several mid- to high-rise mixed-use residential and commercial buildings. Earthquake reconnaissance investigations show the major causes of damaged structure as follows: (1) soft and weak first story and (2) non-ductile detailing. In order to grasp the seismic performance of this type of the buildings, a serious of specimens with the structural characteristics of the typical mixed-use residential and commercial building in Taiwan in the 1990s were designed. A three dimensional, half scale, three-story reinforced concrete (RC) frame infilled with RC walls except the lower two stories has been tested on the novel shaking table with size 8×8m and maximum loading capacity 250 ton. The scaled specimen will be extended to seven-story by applying the concept of modular design, which is going to be tested in the near future. The dynamic behavior and damage features of the building under near-fault ground motions will be studied. In this paper, the design of the specimen, instrumentation layout and the findings from the shaking table test from the near-fault ground motion will be introduced and discussed. On the other hand, the test results provide an important reference for researches on developing the seismic performance assessment tools for mid- to high-rise RC buildings. ? NCEE 2018.
