抄録

A Full-scale reinforced concrete seven-story structure was designed basically according to the U. S. and Japanese building practices and constructed at the large-scale structural test laboratory of Building Research Institute, Ministry of Construction, to experimentally investigate its earthquake response behavior. The structure was carefully supervised in the course of construction to minimize any deviation from the original design, and such attempt was nearly achieved. Before the earthquake test of the structure, the structure's flexibility was experimentally obtained to estimate its elastic properties. It was found from eigenvalue analysis using measured flexibility that computed natural periods are very accurate for lower vibration modes but inaccurate for higher modes. It was also found that the structure's stiffness determined by inverting the measured flexibility can not be regarded as reliable.
