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 history of slab-free slab (slab structure) and the case of a plate and column structure subjected to strong earthquakes in the United States are introduced. The advantages and disadvantages of the seismic performance of slab columns are summarized. The drawings illustrate the structural requirements and practices for the “Code for Design of Seismic Design of Buildings” (GB50011-2010) (6.6.4). The design steps of plate column structure and the detailed requirements for setting anti-seismic walls are given. In the calculation, all the seismic action should be taken by the seismic wall, and the punching shear capacity of the perimeter board should be checked. Impact punching should use studs, plate thickness less than 300mm should not be used stirrup.
