Isolated Low-Rise Building With Eaves

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 isolated low-rise building with varied eaves part of the aerodynamic database. Wind loads on low-rise buildings in codes and standards are mainly based on wind tunnel test results on simple models without eaves. Actually, low-rise buildings usually have various kinds of eaves for the sake of varied eaves on wind loads on gable-roofed low-rise buildings, a series of wind pressure measurement wind tunnel test were taken for gabled-roof buildings with slope of 26.7° with 3 kinds of eaves (Type A, B, C), eave height of models varied in 60, 120, 180cm.
12 test cases are included in the following database, from which the local wind pressures, area averaged wind pressure coefficients and wind pressure coefficient time series on roof or wall surfaces and some more detail information can be queried.
