This article presents the algorithm of monitoring a high-rise building as a complex object. The functional areas (strata) of a high-rise building are considered and certain mathematical models and algorithms describing the process of monitoring a high-rise building are presented. The developed system using this algorithm should allow real-time monitoring of the life support systems, making better decisions in the event of unusual situations.

Frequent high-rise building fires have posed serious threats to urban public safety. In this study, real-time travel times extracted from online maps were applied to estimate fire service coverage rates for high-rise buildings. Firstly, the minimum fire apparatus requirement for high-rise building “at least 1 water fire truck and 1 aerial fire truck should arrive at the fire scene of high-rise building within 240 s” was proposed. Then, a dynamic estimation model of fire service coverage rate for high-rise buildings was established. To validate the model, 5146 high-rise buildings, 61 water fire trucks, and 56 aerial fire trucks in Changsha were selected as case studies. The results show that the total effective coverage rate and total average travel time in Changsha are 20.43% and 421.95 s, respectively. There are 10,840 water fire trucks and 6192 aerial fire trucks in China. Based on the average number of water fire trucks and aerial fire trucks per high-rise building, it can be estimated that the total effective coverage rate in China may not exceed 60.00%. Due to limited fire resources and frequent traffic congestion, only partial high-rise buildings can be effectively covered by fire services, whether in Changsha or China.

Steel-concrete composite structures are widely used in large-span spatial structures, high-rise building, super high-rise building and bridges and so on thanks to its advantages in terms of mechanical and construction properties. And the corresponding design codes on circular, square and polygonal concrete filled steel tube (CFST) have been formed at home and abroad. However, application of round-ended CFST is still very rare in the world and there is no corresponding theoretical research findings and design basis. There is an actual project that a round-ended CFST coupled tower column is applied in Houhu Bridge in Huangpi area, Wuhan city. Real-time stresses of the coupled tower column were monitored throughout construction phase to ensure that the force and linearity of Houhu Bridge can meet its design requirements. In the paper, the real-time stress monitoring data is analyzed so as to find force state and force characteristics of this new structure of round-ended CFST during construction phase. This study provides basic information for further formation of round-ended CFST design theory in future which plays an important role in engineering application of the round-ended CFST.

<p><strong>Abstract.</strong> The paper describes possibilities of the relatively new technics &amp;ndash; ground based radar interferometry for precise determining of deformation of structures. Special focus on the horizontal movements of high-rise buildings and on the tower transmitters is presented. The technology of ground based radar interferometry can be used in practice to the contactless determination of deformations of such structures with accuracy up to 0.01&amp;thinsp;mm in real time. It is also possible to capture oscillations of the object with a frequency up to 50&amp;thinsp;Hz in real time. Deformations can be determined simultaneously in multiple places of the object, for example in the case of high-rise buildings it is possible to monitor the horizontal vibration of the whole object at its different height levels intervals of one or more meters. It is possible to detect and determine the compound oscillations that occur in some types of such buildings. This allows to obtain both overall and detailed information about the properties of the structure during its dynamic load e.g. by wind. Then prevent any damage or even disasters in these objects. In addition to the necessary theory basic principles of using radar interferometry for determining of deformation of structures are given. Practical examples of determining of horizontal movements of high-rise building and tower transmitter are also given. The IBIS-S interferometric radar of the Italian IDS manufacturer was used for the measurements.</p>
