The 1999 Chi-Chi earthquake revealed the poor performance of the RC school buildings in Taiwan. It also indicates an urgent need of seismic evaluation and retrofit for the remaining schools. In order to realize the behavior of a typical school building subjected to lateral load, an in-situ test for an existing 2-story school building was carried out. Three experiments were conducted: static pushover test to identify the strength, stiffness and toughness of the building, and pseudo dynamic test and cyclic pushover test to study the differences between the seismic responses induced by monotonic load or cyclic lateral load respectively. In the pseudo dynamic test and cyclic test, a 2-classroom building constructed in 1926 was cut in the middle where actuators were set for cyclic loading alone the longer axis of building. It is the first in-situ pseudo dynamic test in the world and needs excellent experimental technology and equipments. These experiments also provides great opportunities to further enhance the in-situ pseudo-dynamic test and data archiving techniques, This webpage could present experimental results and some analytical predictions computed from a general purpose frame response analysis program, PISA3D (Tsai and Lin, 2003), simultaneously,
and evaluates the demands imposed on the experimental facilities and the experimental specimen.
