This article is devoted to the initial stages of formation and the prospects of development of BIM technologies, the analysis of the general trends, process of formation of uniform resource space and training of professional engineering staff for transport infrastructure. The main objective of this article is the designation, the analysis of problems and formation of a comprehensive approaches within preparation of the modern level of development of design decisions for informational model which is capable to process in a complex an engineering, technological and economic component and will be relevant throughout all life cycle of an object. In articles authors presented results of poll to PGUPS on a subject “to BIM technology: training of specialists in the field of transport constructions” which convincingly show need of preparation and development of engineering potential for BIM introduction. In conclusions the concept of BIM for bridge projection taking into account start of pilot standard projects with use 3D — projections and with engaging of the modern methods of engineering is presented. The article also discusses the prospects for the development of design in Russia.
The objects of the article are: analyze the work of the main beams of the movable span of the drop-down system near the axis of rotation; analyze the stress-strain state of the main beams of the movable span of the drop-down system near the axis of rotation; analyze the acceptability of the normative methodology (SP) for calculating the stability of the wall of a continuous steel beam during the design and calculation of movable bridge of the drop-down system. A computational-mathematical model of the movable span of the drop-down system is developed in a modern computational software package based on the finite element method. The main disadvantages of the normative methodology (SP) for calculating the wall stability of a continuous steel beam which used in design and calculation of movable bridge of a drop-down system are presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
