Abstract
The research purpose is to clarify the role, significance and problems inherent in transport hubs in the implementation of engineering solutions using new construction materials. The traditional scheme of commutation of passenger traffic between different modes of transport allows building physical models. However, the efficiency of materials in structures and the study of their operational properties are additional tasks for the calculation in new conditions. Historically, many large cities are characterized by a lag in the development of transport infrastructure in comparison with the growth rates of cities. The material and technical supply of construction inevitably faces the problem of the depletion of materials from their operational properties. Massive daily movement of the population to places of job and high operational loads reveal disadvantages primarily in terms of the traditional materials. The way out of this situation is the development of transport interchange hubs, while the use of traditional constructive and technological solutions causes additional difficulties for transport companies and businesses. The presentation of the key elements of the transport infrastructure as a testing ground for testing the properties of new materials such as high-alloy steels, composite materials, superplasticized concretes allows solving the problems of construction engineering in a new way. The constructed transport hubs rarely comply with the loading standards, which is caused by the incorrect approach to their design: the existing construction rules are not comparable with the functional needs of new type facilities. For the assessment, such factors as material consumption, creation of regulatory conditions, quality and safety of materials, reduction in construction time, stability of functioning and others are used. The risks associated with the creation of transport interchange hub (TIH) are noted. The development of transport hubs in a megalopolis can be implemented during simultaneous improvement of the quality of applied construction materials and satisfaction of the commercial interest of investors. In addition to the direct technological effects, there are accompanying operational consequences in various areas of urban life.
