| Abstract | ||
| Buildings with mono-sloped roofs are used for different purposes like at railway platforms, restaurants, industrial buildings, etc. Between two types of mono-slope roofs, clad and unclad, unclad canopy types are more vulnerable to wind load as wind produces pressure on both upper and lower surfaces of the roof, resulting in uplifting of the roof surface. This paper discusses the provisions of wind loads in different codes and standards for Low-rise buildings. Further, the pressure coefficients on mono-slope canopy roof available in wind code and standards are compared. Previous experimental studies for mono-slope canopy roof along with the recent wind tunnel testing carried out at Indian Institute of Technology, Roorkee is briefly discussed and compared with the available wind codes. From the study it can further be asserted that the information available related to staging or blocking under the mono-slope canopy roofs is limited. This paper is an attempt to put together the available information in different wind codes/standards and the research works carried out by different researchers, along with shedding some light on the future scopes of research on mono-slope canopy roofs. | ||
