近二年设计的高层建筑大多具有地库深(设多层地下车库)、柱网大(便于平面布置)及层高低层数多的特点。如今甲方更着重于建筑面积的充分利用,建筑师也把建筑体型设计得更多样化和艺术化。这一切都给结构设计带来新的课题。本文以中房大厦为例,简述大柱网高层结构设计中所遇到问题与难点,以及为之采取的措施:如采用宽扁梁、设置消能柱间支撑、应用高强混凝土等,对大柱网高层结构设计提出探讨意见。 Most of the high-rise buildings designed in the past two years are characterized by deep underground (multi-layered underground garage), large column net (facilitate the layout of the plane), and a high number of floors. Nowadays, Party A focuses more on the full use of the building area. The architect also designs the building body more diversified and artistic. All this brings new issues to structural design. This article takes Zhongfang Building as an example to briefly describe the problems and difficulties encountered in the design of high-rise structures of Dali-Net, and the measures taken for them: such as the use of wide flat beams, installation of energy dissipation column supports, application of high-strength concrete, etc. Large column network high-rise structure design puts forward the opinions.
