摘　　要：日本实际用于超高层建筑的混凝土设计强度已经突破200N/mm2,而且绝大多数都是采用装配式的建造方法。这股超高层钢筋混凝土建筑的热潮,可以说在很大程度上是由于开发高强材料,完善相应的设计方法,以及施工技术的革新所带来的。在该领域,日本技术领先于世界。该文在介绍日本该领域最新动向的同时,概述超高强材料与装配式结构相互之间的关系,并结合作者本人及其团队近几年的研究,介绍关于超高强材料和装配式混凝土结构若干问题的研究成果。The design strengh of the concrete used for ultra-high-rise buildings in Japan has already surpassed 200N/mm2. The overwhelming majority of which were built with the precast construction method. This fasion of ultra-high-rise RC buidings is largely due to the development of ultra-high-strength materials, the conception of new design methodologies, and the innovation in construction technologies. In this area, Japan is the technology leader in the world. This paper includes an introduction of the latest trends of this area in Japan, as well as an overview of the relationship between the ultra-strong materials and a precast concrete structure. It provides also an insight into the recent researches and achievements of the author and his team.
