灵活划分户型的蜂窝型钢空腹夹层板楼盖刚度与舒适度研究

Research on stiffness and comfort of honeycomb steel vierendeel sandwich panel floors with flexible division of house types

该研究提出灵活划分户型的蜂窝型钢空腹夹层板楼盖结构,为研究其静力性能、自振频率特性以及舒适度问题,以某拟建工程为例,采用子空间迭代法,建立ANSYS模型进行分析,并与国家规范规定的相关指标进行对比分析。研究结果表明:楼盖挠度满足跨度1/300的要求;自振频率为8.403 Hz,楼盖的刚度较大;舒适度也满足规范规定的竖向振动最小频率4 Hz的要求,同时楼盖具有节约层高、灵活划分房间和设置喷淋等优势,未来在高层住宅中有一定的应用前景。

This research proposes a honeycomb steel Vierendeel Sandwich Panel floors with flexible division of house types.To study its static performance,natural frequency characteristics and comfort,taking a proposed project as an example,the ANSYS model is established to analyze by using the subspace iteration method,and compared with the relevant indexes specified in the national code.The results show that the deflection meets the requirement of 1/300 span,the natural frequency is 8.403 Hz,the rigidity is relatively large,and the comfort meets the requirement of 4 Hz minimum frequency of vertical vibration stipulated in the code.Due to the advantages of saving floor height and setting the spraying,the future in high-rise residential has great application prospects.
