Two Adjacent Highrise Buildings with Rectangular plan
Introduction
The interference effects between highrise buildings with two different planforms and arrangements are investigated by checking the pressure distributions on building faces. For the pressure measurement test, wind tunnel experiments were carried out in a boundary layer wind tunnel of Tokyo Polytechnic University. The test section is 2.2 m wide and 1.8 m high.
Totally four sets of experiments were conducted for the pressure measurement.
Case 1 : The square section model was the principal building and the rectangular section model was the interfering building.
Case 2 : The rectangular section model was the principal building and the square section model was the interfering building.
Case 3 : The parallel arrangements of two rectangular building models
Case 4 : The perpendicular arrangements of two rectangular models.

 [Approach flow]

The approaching flow represented an urban wind exposure with a power law exponent of 0.27. The mean wind speed and the turbulence intensity at the roof height of the model were 8 m/s and 17%, respectively. Measured longitudinal mean wind velocities, turbulence intensity profiles and power spectrum of wind speeds at roof height is shown in below download file.
Power law index for mean wind speed : 0.27
Power law index for turbulent intensity : 0.32
Turbulent intensity at the top of the building : 0.17
 [Peak value evaluation]

The Cook–Mayne method (Cook and Mayne, 1980) was adopted to estimate the extreme pressure coefficient. The extreme pressure coefficient representing the 50year return period was calculated
using the following equation:
minCp = Cp + 1.4/ac
where Cp and 1/ac are the mode and scale parameter respectively of the extreme pressure coefficient.
