摘要
分别采用等代梁与虚梁两种模型对北京当代MOMA工程异形板无梁楼盖体系进行了整体分析。通过结构自振周期、层间位移、楼板刚度以及配筋量等指标的对比,总结了高层结构异形板无梁楼盖体系的受力特点,给出了异形板无梁楼盖的合理计算模式。并针对楼板开有较大洞口的实际情况,采用SATWE复杂楼板有限元及ETABS分析程序,对异形板无梁楼盖的挠度、配筋及冲切进行了详细的补充计算,给出了该类楼盖体系的实用设计方法和局部补强措施,供类似工程参考。
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.
