The use of technology to protect and produce vegetables and ornamental plants was developed over several adaptation phases that supported the demand for quality and amount of products. These developments also reduced production costs and climate damage to the crops. Many of these adaptations were carried out by farmers on their own initiative, using different materials and devices to solve their problems. This study was carried out at Agricultural Engineering College - Campinas University/UNICAMP, from December 2002 to January 2003, with the objective of evaluating the deformations of the constructive system of bamboo structure for greenhouses, submitted to different spacing among columns, and different vertical strains. It was tested the use of beams and columns built with bamboo stems from the specie Bambusa tuldoides Munro. The beams and columns were tied together with plastic spacing parts, specially designed to facilitate and standardize the construction of the building, providing more resistance and stability. Three column spaces (2.0, 2.5 and 3.0 m) were evaluated under different load strains. The best result was obtained with a spacing of 2.5 m.

This paper presents the behavior of three bored piles conducted in diabasic soil submitted to uplift forces. The piles were built at the site for Experimental Studies in Soil Mechanics and Foundations of UNICAMP, located in the city of Campinas, Brazil. Field tests have already been conducted at the site (SPT, CPT, DMT and PMT), as well as laboratory tests by using sample soils taken from a well up to 17 m deep. The water table is not checked until a depth of 17 m. In order to check the behavior of the piles when submitted to uplift forces, slow static load tests were carried out as the recommendations of NBR 12131. The carrying capacity of these piles was also provided by means of theoretical methods, appropriate for uplift forces, and through semi-empirical methods appropriate for compression forces, considering only the portion of lateral resistance. The values estimated by using the considered methods were compared to those obtained by means of load tests. One of the tested piles was extracted from the soil to be the subject of a study on its geometry.
