Finite element analysis for walking vibration problems for composite precast building floors using ADINA: modeling, simulation, and comparison

摘要

Building floors made of precast double-tee (DT) concrete sections could experience annoying vibration problems due to people walking. From the viewpoint of structural design, the issue of floor vibration acceptability is also important in addition to the conventional strength/safety criterion. In this paper, ADINA-based finite element (FE) techniques are described and discussed in detail for rational analysis and assessment for a large composite floor system subjected to walking vibration. In particular, the techniques of the FE modeling and the consideration and simulation of dynamic loading are addressed. Advantages of using ADINA for vibration studies and recommendations for analysis and design are presented.
