Abstract

The article presents the research results on of a trapezoidal wooden truss with ascending braces on metal tooth plates parametric optimization. A deterministic algorithm has been developed and a program has been compiled that allows you to find the optimal parameters of the truss from the condition of minimizing the volume of wood, for given initial conditions. The optimal parameters for a truss with a span of 24 meters at a given value of the external load are revealed, diagrams of the dependence of the objective function on the varied parameters are drawn.

A trapezoidal timber truss with ascending braces on MTP span L, which perceives the useful linear load q is set, it is required to compose a deterministic algorithm, optimizing the following truss parameters: a) h – support height, b) α – inclination angle of the upper belt, c) n – number of truss panels, d) b – truss thickness

Summary

Introduction

In the world practice of construction production, a significant share is occupied by wooden structures. One of the modern and promising methods of joining wooden structures - metal tooth plates (hereinafter MTP). This fact is primarily due to the high technological and economic performance of this compound [1 - 4]. There is a need to minimize labor and resource costs in the production of wooden structures on MTP. The solution to such problems is reduced to the compilation of an algorithm for optimizing the design parameters, at which the volume of wood will be minimal [5 – 10]. The article considered the possibility of compiling a deterministic parametric optimization algorithm for a trapezoidal wooden truss with ascending braces on MTP span L
