SAFETY AND HABITABILITY OF HIGHRISE BUILDING SUPPORTED BY SPATIAL MEGATRUSS STRUCTURE

Abstract

Takasaki city hall is a high-rise building supported by spatial megatruss structure. Construction method influences to load allotment and building accuracy. It is important to grasp stress conditions and study stress transmission mechanism. And it is necessary to estimate vibration environment of office floors. This paper introduces dynamics behavior of steel beamcentrifugal casting steel pipe column joint with experiments, stress conditions during the construction period and evaluation of habitability to vibration.
