Estudio del comportamiento sismo-resistente de una estructura espacial hexagonal de caña guadúa reforzada con ladrillos artesanales, sometida a carga lateral con inversión y utilizando una modificación de la conexión Simón Vélez

Abstract

In the present degree project the analysis of the seismic-resistant behavior of a guadua cane structure is proposed, implementing artisan brick masonry as a modification of the design proposed in the titling project “Study of the seismic-resistant behavior in a spatial cane structure guadua subjected to lateral loading with inversion, using a modification of the Simón Vélez connection”, developed by Jonathan Herrera and Luis Viteri, at the Escuela Politécnica Nacional, in 2017. This proposal aimed to reduce floor drifts, improving its earthquake behavior -resistant.

The materials used in the structures were previously tested, determining their physical and mechanical properties. The manufactured prototypes were subjected to quasi-static lateral tests with inversion, recording loads and displacements to carry out data processing, generate the hysteresis curve and determine fundamental parameters (dissipated energy, secant stiffness, viscous damping, ductility and reduction factor of seismic behavior), to analyze the seismic-resistant behavior of the same. Furthermore, the elasto-plastic energy envelope curve was elaborated and the elastic and inelastic floor drifts were calculated.

Finally, the results of the two studies were compared, demonstrating the decrease in floor drifts and the increase in stiffness in the structures.
