“…Two greenhouse structures, a vaulted and a Venlo-type, presented in studies "Analysis of the collapse of a greenhouse with vaulted roof" [14] and "Additional design requirements of steel commercial greenhouses in high seismic hazard EU countries" [15], respectively, were used in this study.…”

“…The purlins have a span of 4 m, which is similar to the distance between columns, while the span of the gutters is 2 m and is equal to the separation between the columns. However, this was not the case for frames with missing columns (removed or not installed at all), that is, the span was 4 m. Plastic film was used as the greenhouse cladding [14]. The type of greenhouse is B15 according to EN 13031 [1].…”

Steel greenhouse structures are generally constructed by individual sole contractors using quick empirical structural calculations (pre-engineered solutions). It is also common to import standard greenhouses from other countries, mainly from The Netherlands, Italy, and France, and sometimes from Great Britain and Israel. Evidently, these countries differ concerning the local wind and snow conditions. Therefore, there is a need for a better design of structures accepted as satisfactory, while installation can be done in a different location. Many greenhouse structures incorporating poor designs or inappropriate pre-engineered solutions are currently in use. At the same time, demolition and reconstruction represent a very expensive solution considering the loss of crop production and the demolition and construction costs; thus, strengthening is a reasonable alternative. This paper presents strengthening techniques for steel greenhouses that are code-deficient according to EN 13031 and Eurocodes. Consequently, two case studies are presented as typical applications of greenhouse structure strengthening.

“…South-eastern Spain has the largest concentration of greenhouses with 30,000 ha, although according to 2018 data from the Chinese Ministry of Agriculture [1], China has the largest area in greenhouse cultivation at 3.7 × 10 6 ha. Most greenhouses are plastic-covered structures, and their structural safety has received attention due to the high economic costs of losses from complete or partial greenhouse collapses caused by severe weather such as wind and snow [2][3][4]. The mechanical performance of different greenhouse structures has been studied by numerical methods [5] and finite elements for static loads [6] and dynamic loads [7].…”

Greenhouse cultivation has gained a special importance in recent years and become the basis of the economy in south-eastern Spain. The structures used are light and, due to weather events, often collapse completely or partially, which has generated interest in the study of these unique buildings. This study presents a load and displacement monitoring system that was designed, and full scale tested, in an Almería-type greenhouse with a tensioned wire structure. The loads and displacements measured under real load conditions were recorded for multiple time periods. The traction force on the roof cables decreased up to 22% for a temperature increase of 30 °C, and the compression force decreased up to 16.1% on the columns or pillars for a temperature and wind speed increase of 25.8 °C and 1.9 m/s respectively. The results show that the structure is susceptible to daily temperature changes and, to a lesser extent, wind throughout the test. The monitoring system, which uses load cells to measure loads and machine vision techniques to measure displacements, is appropriate for use in different types of greenhouses.

“…Few studies have been made of the collapse of structures. Briassoulis et al [29] analyzed the collapse of a multi-span greenhouse with vaulted roofs, which occurred during a day of heavy snow and moderate wind. Moriyama et al [30,31] discussed the causes of typhoon-induced damage to several greenhouses based on a linear structural analysis, in which they assumed that the wind pressure coefficient distribution on the structure did not change with the deformation of the structure.…”
