Experimental determination of wind loads on 200 m tall three-tower blocks

摘要

A ease study of wind tunnel investigation on pressure measurement on a 200m tall tower block with an irregular plan shape was carried out. The study has clearly brought the need to include the torsional loading. Based on the test results, a mean force coefficient of 1.65 in the along-wind direction and a coefficient of 1,0 in the across-wind direction with an eccentricities of +- 0.1B is recommended for the design. The effect of interference due to adjacent two similar towers is also reported.
