dc.description.abstractFacing a serious waste management problem, the accumulation of scrap tires represents a huge environmental and health problem not only to Puerto Rico, but also to many nations. It is necessary to consider alternatives for the use of this material in order to alleviate the problem. One of these alternatives is the use of crumb rubber in structural engineering applications in order to prevent buckling. Often defined as a structural instability, buckling could cause slender steel elements to fail suddenly when loaded under compression. However, if the steel elements are confined or possess lateral restrictions, larger loads are then needed in order to cause a buckling failure. Therefore, this project was aimed to perform experimental tests on unconfined and confined (with crumb rubber) slender steel elements to determine the behavior of the rubber as a confining element. In order to meet these objectives, experimental tests were conducted on steel truss beams (confined and unconfined) using two different configurations to determine their maximum capacity when loaded in flexure. A flexural test was also carried out on a hexagonal rubber paver. Finally, analytical models were developed using the structural analysis software SAP2000 to simulate the beam specimens previously tested. It was found that, depending on the configuration of the beam and the crumb rubber, the latter could increase or decrease the load capacity of the structure.en_US
dc.description.abstractMientras Puerto Rico enfrenta un problema serio de desperdicios sólidos, la acumulación de gomas (o llantas) usadas representa un gran problema ambiental y de salud en la isla así como en otros países. Para aliviar este problema es necesario considerar otras alternativas para el uso de este material. Una de esas alternativas es el uso de goma triturada en aplicaciones de ingeniería estructural para prevenir pandeo. Usualmente definido como una inestabilidad estructural, el pandeo puede causar que elementos esbeltos de acero fallen repentinamente cuando están en compresión. Sin embargo, si dichos elementos están confinados o poseen restricciones laterales, se necesitan cargas mayores para que ocurra una falla por pandeo. Por tal razón, este proyecto fue realizado con el objetivo de llevar a cabo pruebas experimentales en elementos esbeltos de acero sin y con confinamiento (con goma triturada) para determinar el comportamiento de la goma como un elemento de confinamiento. Para cumplir estos objetivos, se realizaron pruebas experimentales en vigas conformadas por cerchas de acero (con y sin confinamiento) utilizando dos configuraciones distintas para determinar su capacidad máxima aplicando una fuerza en flexión. Una prueba adicional fue realizada a una losa hexagonal de goma. Finalmente, modelos analíticos fueron desarrollados utilizando el programa de análisis estructural SAP2000 para simular las vigas previamente ensayadas. Se encontró que, dependiendo de la configuración de la viga y la goma triturada, la capacidad estructural puede aumentar o disminuir.en_US
