［摘要］介紹了無梁樓板（板柱結(jié)構(gòu)）的歷史沿革以及美國某板柱結(jié)構(gòu)經(jīng)受強震的情況。概括了板柱結(jié)構(gòu)抗震性能的優(yōu)缺點。附圖講解了《建筑抗震設(shè)計規(guī)范》（GB50011—2010）公式（6.6.4）所需要的構(gòu)造要求及其做法。給出了板柱結(jié)構(gòu)的設(shè)計步驟和設(shè)置抗震墻的詳細(xì)要求。在計算中應(yīng)由抗震墻承擔(dān)全部地震作用，并注意驗算柱周邊板的抗沖切承載力。抗沖切宜采用栓釘，板厚小于300mm者不宜采用箍筋。
［關(guān)鍵詞］混凝土結(jié)構(gòu)；無梁樓板；抗震性能；構(gòu)造建議

Seismic capacity of flat slab column structure
Cheng Maokun(Beijing Institute of Architectural Design, Beijing 100045, China)
Abstract: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.
Keywords:concrete structure; flat slab structure; earthquake resistant capacity; detail design
