摘要
《高层建筑钢-混凝土混合结构设计规程》(CECS 230∶2008)的颁布对我国高层混合结构的设计有着重要的意义,使目前的设计工作可以有章可循。本文参考此规程完成了一钢管混凝土框架-混凝土核心筒结构的设计工作,并在设计过程中与以往的其它规程进行了比较,发现外框剪力调整方法、偏心率、钢管混凝土柱的抗弯承载力计算方法、承载力抗震调整系数、结构阻尼比等均存在商榷之处,在此提出,希望能够为这本规程的应用起到推动作用。
The issue of Specification for Design of Steel-Concrete Mixed Structure of Tall Buildings （CECS 230：2008） will have significant influence on the design of steel concrete mixed structure of tall buildings. A concrete-filled steel tube frame-concrete corewall hybrid structure was designed according to this specification, and comparisons with other specifications were conducted. As a result, sevral problems, such as modifying method of shear force in peri frame, and eccentricity ratio, flexural capacity of concrete-filled steel tube column, modifying coefficient of seismic capacity, damping ratio, are discussed here to promote the application of this standard.
