摘要

To address the wind-sensitivity problem of high-rise connected corridor buildings caused by their high flexibility and low damping characteristics, this paper systematically investigates the wind-resistant performance of such buildings based on a semi-decoupled static aeroelastic analysis method of steady-state computational fluid dynamics (CFD), combined with finite element numerical simulation. Taking high-rise connected corridor buildings with streamlined airfoil sections as the research object, and adopting typical square and elliptical section buildings as control groups, this study verifies the effectiveness of the two proposed wind-resistant measures: the airfoil profile and the connected corridor. The static aeroelastic analysis considers the coupling relationship between aerodynamics and structures, and ensures the matching between the internal structure of the building and the aerodynamic shape through interpolation functions and rapid model reconstruction. With inter-story displacement and torsion angle adopted as evaluation indicators for wind-resistant performance, this paper systematically compares the differences in wind resistance with and without the proposed wind-resistant measures. This quasi-static wind resistance evaluation method based on static aeroelastic analysis can effectively quantify the peak displacement and inter-story torsion angle of the connected corridor under average wind loads, thereby providing a theoretical basis and data support for optimizing the supporting method of the connected corridor and formulating wind-resistant design parameters.
