چکیده

We attempt to compute the dynamic wind loads on tall buildings in close proximity with large-eddy simulation. Computation is attempted on two building geometries on which strong interference effects have been reported in previous wind tunnel studies. The computation uses a commercial code and a simple model of turbulence characteristics of the incident wind flow. The computed along-wind and across-wind force spectra on the buildings could qualitatively explain the observed dynamic interference effects on the buildings, in particular, the modification or generation of large-scale quasi-periodic wind load fluctuations.

NUMERICAL AND EXPERIMENTAL INVESTIGATION OF WIND PRESSURE COEFFICIENTS ON SCALLOP DOME

The wind loads considerably influence lightweight spatial structures. An example of spatial structures is scallop domes that contain various configurations and forms and the wind impact on a scallop dome is more complex due to its additional curvature. In our work, the wind pressure coefficient (Cp ) on the scallop dome surface is studied numerically and experimentally. Firstly, the programming...

Effect of fluctuating wind direction on cross natural ventilation in buildings from large eddy simulation

A large eddy simulation (LES) program with the Smagorinsky subgrid-scale model has been used to study cross natural ventilation in buildings, which has experimental data available from on-site measurements and a wind tunnel. Since natural wind changes direction over time, it is hard to reproduce this effect in a conventional wind tunnel where the “wind” direction is fixed. There are discrepanci...

Hybrid Analysis of Meso-meteorological Model and Les for Strong Wind in Dense Tall Buildings

This paper provides an appropriate method for predicting strong winds acting on tall buildings erected in close proximity to one another at the center of a city. We first check the accuracy of strong winds estimated using the meso-meteorological model (MM5) without an urban-canopy model above and inside an urban canopy, in comparison with the observational data taken at the rooftop of a high-ri...
