Dynamic characteristics of high-rise buildings: In-situ measurements versus FEM calculations
conference paper
The natural frequency is an important dynamic characteristic in the estimation of wind-induced vibration levels in high-rise buildings. A comparison is made between the natural frequencies obtained with design level FEM calculations and in-situ measurements for three high-rise buildings in the Netherlands. The results corroborate earlier findings that the natural frequency is often underestimated in the design phase of high-rise buildings. Ongoing work is looking into the reasons for this underestimation, and aims to establish a basis for guidelines to setup a FEM model for the accurate estimation of the dynamic characteristics of high-rise buildings.
