The shake table test of small-scaled steel frame structure was conducted using large-scale earthquake simulator at the National Research Institute for Earth Science and Disaster Resilience (NIED) in Tsukuba, Ibaragi. This paper presents the performance evaluation of Micro Electro Mechanical Systems (MEMS) type accelerometers, which are recently being used in various fields, comparing with the conventional servo type accelerometers. In addition, this paper discussed the integration method of the measured acceleration into displacements, which is suitable for structural damage evaluation due to strong earthquakes.
