Análisis del comportamiento estructural de muros de corte de pino rigidizados por placas MDP, sometidos a carga lateral monotónica en su plano

Abstract

The present investigation, refers to the structural evaluation of the system of pine shear walls stiffened by particleboard (MPRPA), constructed with wood from forest forests of the province of Cotopaxi. The purpose was to determine the structural capacity of a house composed with this system, before wind and earthquake loads. For this purpose, shear, stiffness and deformation capacity were obtained in the linear range of the walls MP 1x5-12 and MPE 1x8-12 by means of monotonic lateral load tests according to ASTM E-564; and calibrated to a mathematical model with the purpose of generating tools for a modeling that provides results closer to those of laboratory. With the results, it determined that the MPE-1x8-12 wall has a shear capacity approximately two times greater than the MP 1x5-12 walls, and both configurations are ductile structural systems. Also, the structure composed of walls MPE 1x8-12 works on the load requests defined by the NEC 2015 for a specific zone of the Ecuadorian littoral that was affected by the earthquake of the 16 of April of 2016. The investigation seeks to contribute to the design of walls made with local wood and particleborads for future works.
