［摘要］分別采用等代梁與虛梁兩種模型對北京當(dāng)代MOMA工程異形板無梁樓蓋體系進(jìn)行了整體分析。通過結(jié)構(gòu)自振周期、層間位移、樓板剛度以及配筋量等指標(biāo)的對比，總結(jié)了高層結(jié)構(gòu)異形板無梁樓蓋體系的受力特點，給出了異形板無梁樓蓋的合理計算模式。并針對樓板開有較大洞口的實際情況，采用SATWE復(fù)雜樓板有限元及ETABS分析程序，對異形板無梁樓蓋的撓度、配筋及沖切進(jìn)行了詳細(xì)的補充計算，給出了該類樓蓋體系的實用設(shè)計方法和局部補強措施，供類似工程參考。

Abstract:Special-shaped slab-column system used in Beijing MOMA is analyzed by equivalent beam model and conjugate beam model respectively. Behavior and analysis model of special-shaped slab-column system are given by comparison of vibration periods, story drift angle, slab rigid and reinforcing bar. Moreover, due to large holes in slab, additional analysis about deflection, reinforcing bar and punching shear capacity of slab is carried out using SATWE and ETABS. Based on analysis results, design method and strengthening measure of special-shaped slab with large holes are provided.
Keywords:special-shaped slab-column system; equivalent model; conjugate model beam; steel shear connector; hidden beam
