Abstract. The proposition and development of a flex material employing bamboo and timber laminated and glued (Gluelam+Gluebam), which can be fabricated industrially, is a way of reducing the impacts of conventional construction and, most importantly, enable the promotion of small farmers. The application of this material in furniture and urban equipment inserts rural population in the productive system, reaffirming their cultural identity, generating income and promoting employment. However, in order to introduce a new material such as the one that is been proposed, the performance of resistance and structural behavior tests are necessary so that its characteristics are understood, ensuring a technical certification for its application and, above all, the security of users. Thereby, this article intends to characterize the physical-mechanical behavior of bolted connections in a bamboo and timber flex material, aiming its application in the production of a bus stop to be built in Brasilia. The bamboo species used was Dendrocalamus asper and the timber Eucalyptus urograndis, commercially called Lyptus®. Methods consisted in carrying out laboratory compression tests with representative samples of a bolted connection from the bus stop structure, both parallel and perpendicular to grain. Each test was performed with six specimens, and the results were interpreted from the maximum load of rupture, as in accordance with the ASTM D 5652 – 95 international standard test method. The average values of resistance found were 1786,4 kgf in compression parallel to grain, and 1063,84 kgf in compression perpendicular to grain, proving that the connection with the flex material can be applied in light structures such as the bus stop.
