数字孪生技术在高层结构施工受力优化中的应用研究

Digital twin technology provides a new solution for structural stress analysis during the construction of high-rise buildings. By constructing a digital twin model of the high-rise structure, real-time monitoring and dynamic simulation of the structural state during the construction process are realized. This study establishes a monitoring system based on multi-sensor data fusion, uses resistance strain gauges for accurate measurement of floor stress, and develops a digital twin platform based on finite element analysis. Furthermore, a construction mechanics optimization analysis is conducted for a 43-story super high-rise building, focusing on the analysis of floor stress distribution laws, floor joint tensile stress control characteristics, and axial force transmission mechanism of external frame columns. The application results show that after optimization, the maximum floor stress is reduced by 10.5%, the maximum joint tensile stress is reduced by 25%, the axial force deviation of external frame columns is improved by 29.7%, and the deformation control accuracy is increased by 12.8%. These improvements effectively enhance construction safety and structural performance.
