Submission overview

Abstract

Accurate prediction of modal properties is essential for the reliable assessment of wind‑induced vibrations and serviceability performance in the design of high-rise buildings. This study com-pares measured and computed modal properties for seven high‑rise buildings in the Nether-lands. The results show that design‑stage Finite Element Models (FEM) consistently underesti-mate the first translational natural frequencies (in the X- and Y- directions) by 13% to 50%, highlighting accuracy limitations in current modelling practices. These observations suggest that simplifications adopted at the design stage—particularly regarding assumed mass, global stiffness, and foundation conditions—can introduce systematic biases in predicted dynamic properties. The findings therefore motivate targeted sensitivity analyses, currently ongoing with-in the HiViBe project, to quantify the influence of these modelling choices and to support the development of practical recommendations for improving design‑stage FEM modelling for wind‑induced serviceability design.
