APPLICATION OF HIGH-RISE PRECAST PRESTRESSED CONCRETE BUILDINGS IN HIGH-SEISMICITY REGIONS

摘要

The possibility of application of precast preslressed concrete system to buildings up to 60m high in high-seismicity regions is discussed. Three typical types of precast prestressed high-rise buildings are chosen as an object of structural design trial. The buildings are designed according to the guideline coded in a reseach project entitled "Research and Development of Structural Design and Construction Guideline for Precast Prestressed Concrete Structures", organized in Japan Association for Building Research Promotion. This guideline is based on capacity spectrum method which predicts dynamic response using capacity spectrum and demand spectrum. The results of the structual design revealed that precast prestressed concrete system are successfully applied to high-rise buildings even in high-seismicity regions, and that those buildings are comparable to equivalent steel-encased reinforced concrete buildings in terms of structural and economic performance.
