Two Adjacent High-rise Buildings with Rectangular plan

Introduction

The interference effects between high-rise 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.

Experiment Conditions

[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 50-year 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.
