Bar structures are widespread in construction due to their economy, freedom of design shapes and sizes. As a result, automation of design and calculation of such structures is an urgent task. As part of the study, the task of developing a software module that generates a map of optimal cutting of rolled metal based on the results of calculations of rod structures has been implemented. The algorithm under consideration takes into account such features of the cutting optimization problem as taking into account the width of the blade, the possibility of using half the size of the rolled product, support for optimization of several sections, and welding of parts in case the length of the workpiece is exceeded. The software module is developed using JavaScript and C# languages. The ability to automatically generate cutting maps based on the results of optimization of rod structures increases the efficiency of designing building structures.

Bar structures are widespread in construction due to their economy, freedom of design shapes and sizes. As a result, automation of design and calculation of such structures is an urgent task. As part of the study, the task of developing a software module that generates output documents of a web application for calculating bar metal structures has been implemented. The software is developed on the .NET platform using the Spire.Doc and netDxf plug-in libraries. The developed module generates AutoCAD-compatible drawings and text reports in accordance with Russian standard SP 16.13330. The possibility of automated generation of reports allows more efficient use of the computing complex in production, cost reduction and calculation accuracy increase.

It implemented the problem of identification of damaged bearing beams span bridge structures using vibration diagnostics methods, taking into account experimental uncertainties associated with natural hazards and man-made processes. Method fault location is based on analysis of dynamic properties of the structure, such as the natural frequencies and mode shapes. The paper shows the study of finite element model of the bridge structure using the method of determining structural damage indicator based on the values ​​of waveforms normalization taking into account the values ​​of the oscillation area.

The last ten years have seen a rapid growth of research related to the development of methods of localization of defects and assessment of technical condition of metal structures based on dynamic analysis. This paper presents the results of a study on the localization of defects arched steel truss. The main purpose of this article is to analyze the results of the damage index method and the development of the software module to localize structural damage. The results of numerical experiments presented in this article have shown the effectiveness of this method of localization of damage. The use of this method in practice will reduce the time of inspection by pre- defining a site design that are necessary to pay special attention during the field study.
