However, STK are vulnerable to earthquake based on the Taiwan experience. In 2016 during Meinong Earthquake, damage of the STK system led to serious impact on high-tech factories. It not only shut down the production line, caused huge economical lose, but also responsible for slow recovery. This study aims to increase the seismic capacity of STK in a high-tech factory. First, a rough numerical model to realize the true response under earthquake in the factory was developed. By using full-scale static and shaking table test we validated the dynamic characteristic of the numerical model. By considering the in-situ situation, construction feasibility, and the economic demand, a retrofitted bracing system was developed. The efficiency for the retrofitted STK is verified by static and shaking table tests. Finally, the computed response of full STK models in fab showed a most efficient response after the proposed retrofit.enCC-BY 4.0 InternationalConference Contributions - Other
