Adaptive Finite Element Models Coupled with Structural Health Monitoring Systems for Unique Buildings

Introduction. Issues arising from the automatic monitoring of high-rise buildings are considered. One of such issues is the necessity of minimizing the number of sensors when taking the operational patterns of such load-bearing systems. The method of sensor placement in high-rise buildings is described. Materials and methods. Different structural systems of high-rise buildings have common dependencies of longitudinal axis deformation on rigidity of vertical and horizontal load-bearing elements. Calculation of deformations from static wind load, comparison of data obtained by manual and computer calculation, and also comparison of static wind load with the wind load pulsation component are performed. Results. From the analysis of the extrema of the deformation function of the building vertical axis with the horizontal plane of the floor structure preserved, the main typical monitoring points necessary to minimize the number of sensors in high-rise buildings were determined. Based on the typical breaking points, the required number of sensors located 1/4 of the building height away from each other and the range of measured values of deformations that occur during operation were determined. Conclusions. For automatic (constant) monitoring of high-rise buildings, it is advisable to use a complex integrated method of measuring deformations of vertical load-bearing structures, frequencies and amplitudes of oscillations, and rotation angles. According to the general design theory of high-rise buildings and computer calculation models, the most efficient placement of engineering structure monitoring sensors is when they are evenly covering the perimeter of each floor and the entire height of the building. Measurements should be carried out following the outlines of the floor structures on stories located 1/4 of the building height away from each other, as well as on the stiffening core to control the integrity of floor structures and their connection to the stiffness core.

The article is devoted to the analysis of the current state and prospects of development of digital technologies in construction. The fundamental concepts of digital economy, digital production and digital technologies are introduced; a peculiar "evolution" of the design process in construction is described (transition from so-called "paper-based" technologies to computer aided design systems and further to information modeling of construction objects). Contemporary achievements of mathematical and computer modeling of loads and impacts, contemporary achievements and problems of mathematical (numerical) modeling of the stress-strain state, dynamics and stability at the basic and special combinations ofloads and impacts at significant stages oflife cycle of construction object are specified. Digital technologies in experimental and field studies are considered, the interrelation with mathematical modeling is shown, digital technologies in production of materials, products and structures are presented, the brief and substantial analysis of development of computer material science is given. Among the very topical issues raised in the article we should also highlight BIM - a fundamentally new approach in architectural and construction design, which includes creation of a computer model of a new building (structure), which carries all the information about the future of the object and is an instrument of control over its life cycle. Building Information Model is, in essence, a reflection of the ideas of the digital economy in construction and digital technology in the construction economy. The article also explains the concept of so-called "smart" home, "smart" district, "smart" city, "smart" region and "smart" country, which are normally used by professionals in terms of current realities,long-term and medium-term prospects. Finally, the expediency of development of design codes in the field of information technologies is assessed.

In accordance with the state-of-the-art concept mathematical models must accompany objects at all stages of their life cycle (design and construction, operation, repair and reconstruction), providing an adequate and complete analysis and forecast of the state as part of computer-based structural health monitoring systems [13]. Scientific Research Center "StaDyO" (SRC "StaDyO") was founded in Moscow in 1991 as one of the Russian pioneers offering and performing computer-oriented computation services for industrial purposes.…”
