EXPERIMENTAL RESEARCH ON THE MECHANICAL SOLICITATIONS OF THE GREENHOUSES OF VEGETABLES AND FLOWERS LOCATED ON ROOFTOPS

Abstract

This paper presents work algorithm and experimental research results related to the solicitations of the greenhouses for vegetables and flowers placed on rooftops in urban built environment. For research was designed and developed five models of possible forms of greenhouses, which were introduced in HM170 wind tunnel [8]. Air flow speeds to which they were exposed to the front and side surfaces, as well as the roofs of the layouts were 20, 25, 27.5, and 30 m/s. Were measured the pressures in 12 - 16 points on each of the surfaces specified, the data are necessary to design structures of greenhouses resistance of various shapes [2] .All the layouts had the same height and length, but were differentiated by the shapes of roofs and their inclination angles [1].
