The design of engineering structures with metalwork is supposed that corresponding way of operations can support the load-bearing capacity. Because of peculiarities of engineering structures, namely, inaccessibility of a lot of nodes without application of special erection equipment, heavy labour input, etc. – such kind of operation is complicated and sometimes is not carried out. The paper deals with the problems of designing and maintenance of engineering structures with metalwork with specified longevity on the basis of the offered reference methods of principal interaction of designing and maintenance phases.
The design-basis is an idea of presentation of bent and compressed a boundary support unit in the form of a beam on elastic base where a tensile membrane as an elastic base is continuously connected with a boundary support along its full length. Effective building factors of a cross section for a boundary support and a membrane, values of space-stiffness factors are obtained for conditions of Ukraine. Similar numerical research carried out for membrane roof on circular layout together with relative stiffness factors, sag and a lateral load enables to make some aspects of analytical technique of calculation for strength and stability analysis more precise
Monitoring of special structures is more and more widely spread to estimate their state while in use. The forecast reliability is conditioned by a quality of the observation program, equipment and apparatuses, by means of processing and analysis of the observation results. For this purpose there was established a Site for testing PTL supports and tower structures. The Ukrainian Site is a unique universal test bed for static and dynamic tests of both separate constructions and a structure in whole with a continuous recording of time-dependent parameters and processing of the signals obtained, and for studying and collecting statistical information on weather changes and micrometeorological peculiarities of nature effects on a specific object. To solve these tasks, there was developed and approved a universal multi parameter informationmeasurement system. Within the Site there was developed and introduced an automated frost-wind weather-station intended for automatic measurement of the environment hydro-meteorological parameters. There was also established an
