Smart Reliability Analysis of Wind Resistance of Lightweight Steel Structures in Super Tall Buildings in a Smart City

Abstract To improve the stability of the lightweight steel structure of super high-rise buildings, the wind-resistance reliability of the structure is analyzed in this paper. Based on the stress model of the lightweight steel structure of super high-rise buildings, the additional internal forces of the lightweight steel structure under strong wind are calculated, and the stress analysis is completed. Then, the data of the lightweight steel structure node of super high-rise buildings are divided into topographic data and ground object data, and part of the data noise is eliminated by filtering calculation, so as to complete the processing of the measurement data of lightweight steel structure by laser scanning. On this basis, combined with the data obtained, the wind-induced internal pressure and surface net wind pressure of the lightweight steel structure of super high-rise buildings are calculated after the wind-induced failure criterion is defined, and the wind-induced internal pressure and surface net wind pressure of the lightweight steel structure are calculated. Additionally, the wind-resistance reliability analysis is completed by combining the stiffness equation. The experimental results show that the method has high reliability and a short analysis time, which fully proves the effectiveness of the method.
