On the State and Development of Structural Health Monitoring System of the "Evolution" Tower

Abstract

The distinctive paper is devoted to the current and future- oriented state of structural health monitoring (SHM) system of the "Evolution" tower of the Moscow International Business Center (MIBC) "Moscow City". This object is made 54-story skyscraper with a height of 255 meters, twisted around its own axis, located on a three-level stylobate. The paper presents the results of the analysis of scientific, methodological, design and executive documentation for this building and analysis of the current state of the SHM system. In particular, information is given on the SHM system regarding load-bearing structures, control and measuring equipment of a high-rise building, criteria for assessments of technical condition of load-bearing structures, facade structures, results of the analysis of the reliability of monitored parameters, efficiency (accuracy) and the reliability of the mounted SHM system. Then substantiated recommendations for modification of this SHM system are provided. Corresponding recommendations deal with spatial coordinate monitoring using GLONASS/GPS sensors and monitoring of facade structures (control parameters for translucent facade systems; equipment for monitoring facade systems). Besides, recommendations for the development and integration of adaptive finite element models of load bearing and facade structures are provided. The necessary links are given to the authors' papers devoted to developed computational and experimental methodology of structural health monitoring dealing with load-bearing structures of unique buildings in terms of formulation of original basic theoretical foundations of advanced methodology of structural health monitoring, parameterized finite element models of buildings ("design" and "monitoring oriented" models), adaptation (calibration) of finite element models in accordance with results of measurements, structural evaluation in the real situation.
