Estudio del comportamiento sismo-resistente en una estructura espacial de caña guadua sometida a carga lateral con inversión, utilizando una modificación de la conexión Simón Vélez

Abstract

In the present titling work an experimental technical study is carried out on the seismo-resistant behavior of a guadúa cane spatial structure that uses a connection different from those found in the norm for the union of structural elements, in order to generate knowledge that does not exist regarding the use of the material in the constructive practice. Before carrying out the tests, were researched, compiled and analyzed information related to definitions, characteristics and physical-mechanical properties of the material in order to acquire knowledge that will help us to consider the configuration of both the structure and the connection raised. The tests were carried out through quasi-static cyclic lateral loading in guadúa cane spatial structure Angustifolia kunth, with the purpose of analyzing the seismic-resistant behavior of the structure based on the proposed connection and to obtain a behavior trend for this type of structures in the presence of earthquakes. From the experimental hysteretic curve obtained after the test, were determined parameters that establish the resistant seismic behavior of the system; Among the parameters analyzed are: dissipated energy, secant stiffness, resistance degradation, viscous deadening and ductility.
