In recent years, the overall scale, construction speed, complexity and difficulty of engineering construction in China are unprecedented. Large-scale complex structures have exceeded the structural design specifications in terms of complexity, structural form and system. The existing engineering verification methods have limitations and technical bottlenecks, the use of theoretical methods, numerical simulations, and laboratory tests cannot solve the engineering verification problem of complex structures. A technical challenge for understanding the performance of large-scale complex structures in real construction and service environments was proposed. For complex engineering structures such as high-rise buildings and long-span bridges, the paper proposed the distributed synchronous acquisition and mobile sensing data acquisition method. The automatic stochastic subspace method was used to identify structural modal parameters. It could lay a solid foundation for the interpretation of the mechanical mechanism of engineering structure behaviors under operating conditions.
