“…Based on the Fuzhou Yuyang Central Jinzuo Project, Zhou modeled and numerically analyzed the key systems of the jacking steel truss and carried out on-site monitoring of the steel truss to ensure safe operation during jacking and construction. According to the monitoring results, some suggestions were proposed to ensure construction safety [13]. Gao et al, monitored the deformation of a super high-rise building using vibrating wire strain gauges during the construction of 10 to 48 floors and compared the monitoring results with the numerical analysis results.…”

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.
