An Electromanetic Seismic Simulator (EMSS) is proposed for full-scale testing of buildings, industrial equipment and infrastructure. The EMSS is based on an electromagnetic actuator which is moade up of a field and a drive coil. The basic module, which can be deployed in a variety of arrays, consists of three actuators (one vertical and two horizontal). The design provides a linear force characteristic at all displacements, and velocities. An example design of a 3x3 module array is presented that is capable of testing a full scale 10-storied building using the actual signal of the Kobe earthquake. This paper deals primarily with the design characteristics and the performance of the actuator under realistic seismic signals.
