摘　　要：介绍了无梁楼板(板柱结构)的历史沿革以及美国某板柱结构经受强震的情况。概括了板柱结构抗震性能的优缺点。附图讲解了《建筑抗震设计规范》(GB50011—2010)公式(6.6.4)所需要的构造要求及其做法。给出了板柱结构的设计步骤和设置抗震墙的详细要求。在计算中应由抗震墙承担全部地震作用,并注意验算柱周边板的抗冲切承载力。抗冲切宜采用栓钉,板厚小于300mm者不宜采用箍筋。The application of flat slab column structure in earthquake zone is described and the performance of a flat slab building in strong earthquake in America is introduced.The merit and demerit of seismic capacity of flat slab structure are summarized.The detailing requirements of the formula（6.6.4）in Code for seismic design of buildings（GB50011—2010） of China is explained with drawings.Design steps is summarized and the requirements of adoption of shear wall is introduced in detail.Earthquake action must be beared by shear wall totally in calculation.The design methods and detailes are provided.The calculation of punching shear capacity of slab should be paid attention to designer.Shear studs have better punching shear capacity.Hoopings are not suitable in slabs of thinner than 300mm.
