## Non-isolated Low-Rise Building

### Introduction

An aerodynamic database has been constructed by the Tokyo Polytechnic University as one part of the Wind Effects on Buildings and Urban Environment, the 21st Century Center of Excellence Program, 2003-2007, funded by the Ministry of Education, Culture, Sports, Science and Technology, Japan. Present work is the non-isolated low-rise building part of the aerodynamic database, that is, for low-rise buildings in different surrounding conditions. Although many researchers focus on the effect of surrounding buildings on wind loads of high-rise buildings, few deal with the cases of low-rise buildings.
A series of pressure measurement wind tunnel tests were taken for 3 types of low-rise buildings (flat roof, gable roof and hipped models) surrounded by similar low-rise buildings. Its objective is to investigate the interference effect of surrounding buildings to wind loads of low-rise buildings. The surrounded buildings are arranged in 3 kinds of orders (i.e. regular, staggered, random), with 8 different area density $$C_A$$ (0.1, 0.15, 0.20, 0.25, 0.30, 0.40, 0.50, 0.60), and the heights of target building and surrounding building models are all varied in 60, 120, 180cm.
111 test cases are included in the following database, from which the local and area averaged wind pressure coefficients and wind pressure coefficient time series on roof or wall surfaces and some more detail information can be queried.
