Structural analysis of greenhouses: A case study in Turkey

This study was carried out to determine the structural and functional characteristics of the greenhouses in greenhouse enterprises of Turkey. Greenhouse enterprises are widely common along the Marmara, Aegean and Mediterranean cost lines. Marmara region was selected as the study area since it is the pioneering region and has large areas allocated to greenhouses, and has various greenhouse types. Information about greenhouse types, material properties, placement, and arrangement of greenhouses in the study area was gathered by a questionnaire; then greenhouses in enterprises were divided into groups based on cover material, load bearing materials and directional placement. A total of four types of greenhouse with the most economic cross-section, one from each group, were selected and load acting on structural members of greenhouses were calculated. Loads acting on beams of each greenhouse were analysed by Force Method and Moment Distribution Method. The results obtained were compared statistically to determine the best methodology for structural analysis of greenhouses. As a result, no statistical difference was found between moments and shear forces obtained from both methods. However, a difference occurred based on greenhouse types and it was determined that the values obtained for trussed block greenhouse were higher than the other ones.

Analysis of climate factors for the development of greenhouses in Eastern Blacksea Region

Eastern Blacksea Region is one of the less developed regions of Turkey in agriculture. That is why greenhouses are incited as an alternative income source for the region. In this study, aiming to evaluate the suitability of the climate conditions for greenhouses, heating and ventilation requirements for initially proposed two model greenhouses were calculated based on multi-years climate data. Climate parameters of region provinces were also evaluated and they were compared with climate characteristics of Samsun Province, where there were intensive greenhouse practices. As a result, it was determined that coastal provinces of the region had significant similarities with Samsun Province and they were more suitable than the inner provinces for greenhouse practices. Depending on the evaluations carried out, advantages and disadvantages of the region for greenhouse practices were determined and recommendations were made to regional producers.

222Rn concentrations in greenhouses in Aomori Prefecture, Japan

Greenhouses are possible places with high 222Rn concentrations, since soil, the source of 222Rn, is directly exposed inside them. To examine this point, 222Rn concentrations in 28 greenhouses at five locations in Aomori Prefecture were measured for approximately 1 year with passive Rn detectors. For 1 week, measurements of 222Rn concentration and working level were also carried out with active detectors to get equilibrium factors and the ratio of 222Rn concentration in working time to non-working time in selected greenhouses. The geometric mean of annual 222Rn concentrations in greenhouses was 13 Bq m-3, and the same as that in dwellings and lower than that in indoor workplaces in the prefecture. However, variation of the 222Rn concentrations was far larger than in other environments, and ranged from the lowest level in outdoor workplaces to the highest level in indoor workplaces. Significant seasonal variation was also observed in 222Rn concentrations. The mean effective dose from 222Rn and its progenies was estimated to be 0.047 mSv year-1 for a farmer working in a greenhouse.
