Abstract

Three-layer sandwich panels are widely used in insulation of walls and roofing of buildings and other various structures. At the moment building products markets are full of various types of panels by produced different manufactures but skinned with one and the same material only. Panels skinned with two different types of materials are widely used in the sphere of transport. It may be also of considerable economical effect in building engineering. The article presents an analysis of the current state of the problem of calculation of thin-walled profiles in load-bearing structures. The authors developed a program of automated calculation of three-layer panels. The program is certified in Russia. The program allows you to optimize the panel parameters according to the cost criterion. The article presents the basic calculation ideas incorporated in the algorithm of the program. The figures show the program interface. To date, the program has only one Russian language interface. The paper introduces automated methods of singleand multi-span sandwich panels trial design. Different types of materials can be used while skinning these panels. Their middle-layer shift and compliance of supporting structures are taken into account.

Summary

Introduction

Thin-walled metal structures are widely used as bearing structures of buildings and structures [1-18]. Three-layer sandwich panels are widely used in insulation of walls and roofing of buildings and other various structures. These panels consist of two rigid sheathings glued to a comparatively light middle layer. The main characteristic feature of these structures is their middle layer shearing capacity Their middle layer can be made of separate mineral-cotton bars, which have been cut and stabbed together. Panels skinned with two different types of materials are widely used in the sphere of transport. It may be of considerable economical effect in building engineering. The increasing volume of use of thin-walled profiles in construction gave rise to the development of programs for automated calculation of such structures [19, 20]
