THE USE OF COMPUTER DYNAMIC SHAPING FOR MODELING OF ENGINEERING STRUCTURES AND BUILDINGS
SHAMBINA S.L., VIRCHENKO S.G.
Abstract

This article analyzes some aspects of the use of variant dynamic shaping for computeraided design of various engineering constructions and buildings. The proposed method is a further development of structural-parametric approach for geometric modeling of technical objects which was developed by scientific school of applied geometry National Technical University of Ukraine «Igor Sikorsky Kiev Polytechnic Institute».

COMPUTER PROGRAM CALCULATION ACCURACYHINGE-BAR SYSTEMS
BОNDAREV А.B.
Abstract

This article gives an overview and analysis of previous studies, as well as computer programs for calculation of accuracy, including construction steel. The description and analysis of the functionality of the new computer complex "Dimensional Analysis of beam structures" (VC RASK). Verification of EC RASK, confirming the correctness and accuracy of the calculation accuracy. Achieved description of the user experience technology with various menus and the whole VC RASK. An example of the calculation accuracy of the example odnopoyasnoy hinged-rod metal shell. The general form of hinged-rod with metal objects to using the VC RASK can be made exactly the calculation can be varied: a cylindrical, spherical, elliptical, toroidal, conical and other.

NONLINEAR SIMULATION OF AIR-SUPPORTED STRUCTURES
Mokin N.A.
Abstract

Technique of the nonlinear numerical analysisof the air-supported structures including fluid-structural interaction (FSI) has been described in the present paper. Numerical simula- tion of the tunnel test of large-scale air-supported model has been carried out as example of using this technique. The comparison of the experimental and numerical resultsdemonstrated applicability of proposed technique to the considered class of problems. Opportunity to de- velop this technique to the more complicated and advanced problems has been shown, too.

USING PLASTIC HINGES IN THE CALCULATION OF THE BUILDINGS ON THE PROGRESSIVE COLLAPSE UNDER FIRE EXPOSURE
Avetisyan L.A.
Abstract

In this article, the study of the strength of a 25-storey reinforced concrete frame against progressive collapse under fire conditions is presented. Taking the angles of disclosure of plastic hinges as norming for the strength of reinforced concrete elements, a computer tech- nique program has been developed, included in PR Wolfram Mathematica 10 for the dynamic calculation of compressed reinforced concrete elements under fire exposure on the basis of the conducted experimental studies. Dynamic calculation of the strength of eccentrically compressed reinforced concrete columns was carried out, working in normal conditions and under high temperatures. The diagram «moment-curvature» and the graph of change of the static and dynamic strength of the column depending on the temperature were developed. Nonlinear dynamic analysis of a 25-storey reinforced concrete frame was conducted, taking into account the changes of the dynamic characteristics of reinforced concrete elements under fire and, the estimation of resistance of the frame was given.

ACCURACY EVALUATIONOF THE NONLINEAR STATIC ANALYSIS METHOD OF THE STRUCTURES SEISMIC RESISTANCE
DZHINCHVELASHVILI G.A., BULUSHEV S.V.
Abstract

The article considers the practical application of a technique of nonlinear static analysis of seismic resistance of buildings and structures. The calculation of one-storey steel frame, by nonlinear static and nonlinear dynamic methodsis fulfiled. As a result of analysis of the calcu- lation, results show the importance of higher vibration modes and the need to analyze their effects on the system response

Abstract

It is shown that optimization of measures for creation of building structures in under- ground mines is an effective way to improve the performance of underground construction and Geotechnology. Reliability management as containing objects of mountain rock masses in- creased by the use of residual bearing capacity of the destroyed rocks with the adjustment of the dimensions of the structural units of the process means

JUSTIFICATION OF CHANGE OF THE ARRANGEMENT OF ALIGNMENTS OF DAMS AT COMPLEX USE OF WATER RESOURCES OF HYDROGRAPHIC DEMARCATION OF THE MANABA
FERMIN K.A., SINIChENKO E.K., GRITsUK I.I.
Abstract
In 1990, it agrees with the Integral development plan for water resources of Demarcation of Manabi - (PHIMA), for flood of the territory in the field of an irrigation and water supply, 7 projects of complex appointment were identified. For each of them, as a first approximation, the corresponding alignment for an arrangement of a dam is offered and the preliminary sizes of the main hydraulic engineering constructions are determined. Since then there passed 26 years and the offered alignments and topographical and hydrometeorological information for projection of reservoirs, taking into account time, could influence the accuracy of the end results. On the basis of actual hydrometeorological and topographical data, the scheme of development of water resources for hydrographic demarcation of Manabi, Ecuador is offered. In the article, advantages of a new arrangement of alignments of dams are given to Ayampe, Sancan, Cayo, Jama and Coaque that will lead to the considerable decrease of social and ecological consequences, and also the sizes of hydraulic engineering constructions with decrease in the material and labor inputs at construction.
