The paper deals with the perception and image of town Cheb in context historical heritage. Since 2017, has been running a tour historic trusses. aim research was to determine influence this activity on town, or whether roofs already form part at least for some Czech residents citizens. So far, city not systematically investigated. Two surveys have carried out, one among citizens Republic. It fo...

Objective . The purpose of the study is to prove features operation largespan flat structures, which are also taken into account in their design. Method. A technique presented that makes it possible reduce span bending moments. Examples rational design beam trusses given. Result. given structural diagrams, as well analysis work, allow designing large-span systems form frame and arch have high r...

We use support theory, in particular the fretsaw extensions of Shklarski and Toledo [ST06a], to design preconditioners for the sti ness matrices of 2-dimensional truss structures that are sti y connected. Provided that all the lengths of the trusses are within constant factors of each other, that the angles at the corners of the triangles are bounded away from 0 and , and that the elastic modul...

Abstract The advent of additive manufacturing technologies significantly encouraged the development and usage lattice structures. This paper aims to experimentally investigate influence dimension, building position, orientation on mechanical properties Ti6Al4V trusses, manufactured by electron beam melting process, be used in cells. Specimens were considering following parameters: truss diamete...

In this article on increasing the efficiency of steel combined structures, tasks rational design, regulation and control structural parameters elements, use steels with increased mechanical properties are considered. It is shown that for a six-span stiffening girder truss elastic supports, which operates under distributed load, moment 72 times smaller than single-span beam. suggested to high-st...
