Shaking Table Test on Indoor Seismic Safety of Highrise Buildings (Part II. Movement of Furniture under Long Period Earthquake Ground Motion)

Abstract eng:
Long period components of earthquake ground motions may amplify the response of large scale structures with long natural periods such as high-rise buildings, long-span bridges and oil storage tanks. From the computer simulation, the maximum displacement at the top of a 40 story high-rise building in Tokyo exceeds 1.5 m under a long period earthquake ground motion caused by Tokai, Tonankai and Nankai Earthquakes, and the shaking of the building continues several minutes. To examine the safety of the living space in high-rise buildings, a new shaking table called “BRI Large Stroke Shaking Table” was developed in the Building Research Institute. Using this shaking table, movement of furniture inside the rooms of high-rise buildings was examined to find the safety criteria for the design of high-rise buildings.
