Recently, with an increase in the number of high-rise buildings, cases where wind loads exceed seismic loads heve begun to appear. Due to the fact that the shape of a building has a great influence upon the characteristics of the wind load, the wind load acting on buildings is usually estimated by carrying out wind tunnel tests. Although a wind tunnel test is the most reliable method at present, actual phenomena including the unsteady state of a natural wind can not be completely simulated. There are very few examples of full scale measurements of wind loads on actual buildings due to the fact that natural phenomena are arbitrary and costs for the measurements which must continue over a long period of time are extremely high. Results obtained from actual measurements under the condition that they are made in accurate ways indicate actual phenomena. Therefore, it is very important to accumulate data which can not be obtained from wind tunnel tests by carrying out actual measurements in order to improve the estimated precision for wind loads.
This paper shows the results obtained from a comparison between the result from the full scale measurement for the wind velocity and wind pressure obtained at Chiba Port Tower during Typhoon 19 in 1991 and the result from the wind tunnel test corresponding to the full-scale measurements.
