| THE FIRST SECTION AKTIVITIES |
|
At the first section activity (ELABORATION OF ANALYTIC AND DESIGN METHODS OF THE STRUCTURAL METALWORK) a key specialists and outstanding experts from Ukraine (Perelmuter A., Mykitarenko M., Pichugin S., Semko O., Davidenko O., Bilyk A. and others), Poland (Yankovyak R, Zhmuda Ya., Rzhadkovsky Ya., Savinsky P. and others) and from Estonia (Kulbah V., Kivi E.) took participation.
Among the main topics which were under review during sessions at this section were problems related with calculation, design and examination of the building structures with application of SCAD Office system. M. Mykitatenko (OJSC "V. Shimanovsky UkrRDIsteelconstruction", Kyiv) delivered information on this issue. It was pointed out at the presentation of his paper that SCAD Office is a general-purpose multi — functional system, specially worked out for analysis and design of the construction projects. This system is used more than 10 years in many countries for calculation, design and examination of various building structures, including ones made of metal. The structure and potentialities of computational complex along with an examples of its application in practical work are demonstrated.
Peculiarities of influences on members under deformation, affecting on stress-and-strain state of the frameworks used in single-storey industrial buildings were analyzed in the paper presented by Òåreschenko Yu. and Kuklin F. (Kharkiv Complex Department OJSC "V. Shimanovsky UkrRDIsteelconstruction", Kharkiv). The principal trusses and girders as well as secondary trusses are treated in the capacity of the framework members. A quantity assessment of effect due to supports separation, influencing on general stress-and-strain state of the framework is given also. A conclusion was drawn as to necessity to coordinate the normative sizes of expansion building units with their structural solution and for frameworks with discontinuous girder structures at the same time it is essential to make calculations, taking into account the temperature influences irrespective of expansion units sizes.
In the report presented by Pichugin S. and Semko O. (Poltava National Technical University named after Yu. Kondratyuk, city Poltava) the findings of investigation are presented, dealing with behavior and calculation of steel beams with cuts, arranged at flanges, which may be considered as one-lateral structural defects. The solution of this problem makes it possible to define more precisely the internal forces in beams having such types of defects, which may lead to reduction of expenses on reinforcement while fulfilling the strength conditions or to make assessment of real danger due to defects in the case of reinforcement failure. Making of experimental research with beams made of I-section ¹ 14, where was performed cuts various in length, but similar in depth allowed to reveal the forms of the samples destruction, in particular for beams with longer cut a torsion of the damaged cross-cut was observed, at the same time for samples with shorter cut such torsion has not been exhibited.
The paper presented by Shimanovska M. (OJSC "V. Shimanovsky UkrRDIsteelconstruction", Kyiv) is devoted to design and analysis of the cable systems, composed of two groups of cables under mutual crossings. A characteristic feature of these systems is an ability of cables to slip freely along each other. In the course of suspended roof systems design it is essential to attack the problem regarding the initial shape of roof system surface. It was found that shape of system provided with slipping cables can be considered as initial both for membrane roof system and for suspended roof system as well.
In other papers a question of the integrated design with prescribed longevity with application of chrome-nickel steel, having some damages was raised (Zubets A., Matchenko T.) along with application of various design models in engineering computations of steel unlined large diameter chimney stacks (Bilenko P.) and analytical simulation of function related with steelwork mass under selection of the most rational structural solutions in trusses, made of steel, etc.
