[摘要]比較了國內(nèi)外三個(gè)主要規(guī)范:英國規(guī)范 BS8110—1997、美國規(guī)范 ACI318—2005及我國規(guī)范GBJ130—90關(guān)于板柱結(jié)構(gòu)在垂直荷載作用下推薦分析方法的不同特點(diǎn),通過算例考察了不同規(guī)范之間、同一規(guī)范不同方法之間的差異性,并與桿、殼單元模型的有限元分析方法進(jìn)行了比較,探討了實(shí)用設(shè)計(jì)方法與有限元法之間的差別,指出了實(shí)用設(shè)計(jì)方法的不足。通過有關(guān)試驗(yàn)成果驗(yàn)證了有限元法的準(zhǔn)確性,并提出了設(shè)計(jì)建議。

Abstract:On analysis of flat slab structures under vertical loading, three existing code methods are introduced: BS8110, ACI318 and China code GBJ130—90. Based on a project example, compared with the finite element analysis results and the experimental test results, it examines the accuracy with which the foregoing code methods used for analyzing flat slab structures under vertical loading, and points out the deficiency of code methods. Finally, the accuracy of finite element analysis method is examined in light of a test results, and the proposed method is presented for design of concrete flat slab structures.
Keywords:slab-column structures; structural analysis; equivalent frame analysis method; finite element analysis
