Determination of the tensional state of a chapel-type greenhouse in tropical climate areas

Abstract

The present work has to do with a chapel type greenhouse’s structure analysis; which through a simplified model is subdued to 120 km’s tropical winds, determining the tensional situation that it shows when performing on loads of winds in two directions (lateral-frontal). In the investigation the Von Misses tensions are evidenced associated to the labors that cause the wind loads on each element, comparing the results with the elastic limit of the used material, besides, displacements are also offered which occur in the knots due to action loads. This is obtained by using the RAM Advanse program, 5.1 version; applying two load combinations that consider the weight itself and the wind loads with their respective increasing coefficients. Finally, the conclusions derived from the analysis of the obtained results are expressed.
