Wind pressure characteristics of elliptical retractable dome roofs

Thermal Behavior of Domed Roofs, Case Study: Historical Dome-Shaped Roofs of Isfahan

Wind pressure measurements on full scale flat roofs

A flat roof surface is known to be subjected to unusually high suction associated with a pair of vortices created under diagonally skewed wind. Prediction of the wind load and its influence on the roof system is an important engineering topic but wind tunnel testing of this situation is not easy with a scaled model. Considering the physics of wind flow for the most critical case, a possibility ...

Genetic Characteristics and Environmental Parameters for Growing Turfgrass in Closed and Retractable Dome Stadiums

Vigorous plant growth without sunlight is routinely achieved in commercial hydroponic lettuce and tomato production using electric lamps. This same technology can be used to maintain live turf grass in closed athletic stadiums. It can also be used to supplement natural sunlight in retractable roof stadiums. The challenge is to determine the optimal combination of genetic characteristics and env...

NUMERICAL AND EXPERIMENTAL INVESTIGATION OF WIND PRESSURE COEFFICIENTS ON SCALLOP DOME

The wind loads considerably influence lightweight spatial structures. An example of spatial structures is scallop domes that contain various configurations and forms and the wind impact on a scallop dome is more complex due to its additional curvature. In our work, the wind pressure coefficient (Cp ) on the scallop dome surface is studied numerically and experimentally. Firstly, the programming...

thermal behavior of domed roofs, case study: historical dome-shaped roofs of isfahan

as a covering method of buildings` roof, domed roofs have mostly been applied in iranian vernacular architecture and also in the middle east region according to adobe material abundance comparing with timber. furthermore, dome remains in the first place in architectural designs due to large area coverage and favorable thermal performance; so that it has been widely utilized in mosques, shrines,...
