Real data and numerical simulations-based approaches for estimating the dynamic characteristics of a tunnel formwork building

摘要: Due to their expected high seismic resistance, a significant number of tunnel formwork buildings have been built over the past few decades, especially in regions hazard. However, only real data analyses reported and are available so far. Different techniques, including analysis, numerical simulations, combination, are employed investigate compare potentials for estimating different aspects building. This study is based on from 16-story residential building Istanbul, Turkey. The analysis building’s dynamic characteristics both vibrational (spectral analysis) waveform (deconvolution interferometry) approaches, which yield information soil–structure system fixed-base For this purpose, dense ambient vibration/generated source measurements earthquake recordings temporary permanent networks used. Furthermore, finite element (FEA) carried out. order first bending torsional modes reversed results simulations compared those data. can be attributed simplifications assumptions made structures. It emphasizes importance analyzing better constraining simulations. Finally, response (synthetic seismograms) input calculated using FEA. Deconvolved wavefields synthetic estimated. Despite changed modes, deconvolved cases match very well.
