基于人群走动仿真的楼板振动时程分析方法的技术研究

2008年上半年,我开始研究大跨度楼板的振动分析方法,通过研究发现,很多理论来源于单自由度体系的公式推导,对于特殊边界及支承条件的楼板,这些公式显得太过粗糙。因此,我在考虑基于SAP2000良好的二次开发环境,做一个楼板振动分析的前后处理,接入SAP2000进行时程分析.基于这些思考,我开始了楼板振动分析的研究,研究了半年时间,初步出了一些成果。
对于楼板荷载生成程序及人群活动楼板振动的验算理论,我总结了一下,并写成论文《The Research of Time-History Response Analysis of Floor Vibration Based on Simulation of Group Walking》(《基于人群走动仿真的楼板振动时程分析方法的技术研究》)发表在国际会议《2008建模、计算、仿真、优化及其应用学术会议》,并发表在论文集上面,现与大家分享一下。

The Research of Time-History Response Analysis of Floor Vibration Based on Simulation of Group Walking

Abstract. Occupant comfort when large-span floor systems are subjected to crowd-induced vibrations has become an important index to evaluate serviceability of structures. Control of deflections stipulated in current code requirements cannot sufficiently represent the serviceability requirements of floor systems. Harmonic vibration analysis procedure is introduced by foreign code requirements to deal with floor vibrations, with the restriction to those with regular shapes and simple boundary conditions. This paper proposes a time-history analysis program for the generation of load induced by human activities based on the stimulation of group walking, analyzing the floor systems with special boundary condition, span and damping by time-history method. Compared with the results of crowd-induced load experiment, the analytical results confirmed the accuracy of this analysis procedure in representing the characteristic of crowd-induced floor vibrations,which is applicable for evaluation of floor systems with arbitrary shape and boundary condition.

Keywords: floor vibrations; time-history analysis; crowd-induced load; group walking stimulation
