“…Taking a super high-rise project in the Yanta District of Xi'an as the subject, this paper uses Midas Gen 2022 to establish a finite element model to simulate and analyze the member stress and the inclination angle of the main column of the jack-up steel platform. The field monitoring data are compared with the simulated values to obtain the degree of agreement between the two stress values, and then the safety evaluation of the project is carried out [15][16][17].…”

To ensure that the steel truss used in a super high-rise building in Xi’an remains in a safe and reliable state during the construction and jacking process, the jacking steel truss and the main column are studied. A finite element model of the steel truss and the main column is established by using finite element software. The stress values of the steel truss and the main column under various working conditions are simulated, and the stress and perpendicularity of the key points of the structure are monitored via the stress monitoring system under different working conditions. Through the monitoring system, the data on the operation of the steel truss are collected, and the monitoring data are compared with the finite element simulation data to ensure the safe operation of the steel truss. The results indicate that the inclination angle of the main column is easily disturbed by the external environment. The main column is inclined in two directions, but it does not exceed 0.3°, indicating good verticality. The stress monitoring values are generally close to the simulated values. The peak values of the stress at the measuring points during the construction stage are the same as the results obtained from the field test, and the error between the measured maximum stress value and the simulated value is controlled within 10%. In general, the simulated values are in good agreement with the measured values.

“…The analysis of publications [17][18][19][20][21] shows that the development and improvement methods are mainly focused on forming systems used for building new properties, where a form, being a permanent structure, often becomes a part of the structural elements to be erected. This approach allows reducing labor input in construction, improve the quality of construction works and cut down construction costs.…”

The authors suggest a new forming system designed for strengthening certain structural elements, by means of widening, for the purpose of reconstruction of buildings and works. A prefabricated “transformer” decking is a versatile forming system, which can be arranged both as a three-dimensional closed P-structure and as a flat structure, depending on the purpose or type of a specific structural element to be strengthened and the work method to be employed. It is also technology intensive, requiring approximately 3-4 times less labor effort as compared to conventional small-panel forms used for reconstruction and overhaul of construction systems. The newly developed forming system is consistent with the environmental safety requirements, having a deck made of porous artificial wood instead of natural wood, as was previously substantiated by the authors’ calculations. Because porous artificial wood, having all the benefits of natural wood (i.e. ease of processing), is free of its drawbacks, a “transformer” form is flameproof and moisture resistant. Enhanced usability of such a forming system is achieved through the use of a material reliable in operation and easy for processing.
