Determination of the Geometric Parameters of Round Logs as Functional Materials for Wooden Housing Construction

Abstract

The article is devoted to the study of strength and thermal insulation properties of logs OBrien. To prevent shrinkage and surface cracks it is proposed to dry logs through the through longitudinal hole. The proposed method is the method of determining geometric parameters of longitudinal openings for the drying of logs, provided that the strength of the logs for a given it load in the design of the exterior walls of the typical wooden house. The stress-strain state of round logs in the outer walls of a wooden frame with a longitudinal hole diameters was studied. It was found that the most dangerous for the considered loadings are the stresses along the contour of the holes. The dependences obtained for the appointment of the diameter and position of holes of the load acting on the beam showed that the holes can be different, depending on the position in the log height of the structure. It was justified, based on the thermal resistance from geometric parameters of round logs.
