Application and effect evaluation of BIM technology in seismic design of high-rise buildings

This paper discusses the application of Building Information Modelling (BIM) technology in the seismic design of high-rise buildings, focusing on digital modelling based on BIM, seismic performance optimisation algorithm, structural analysis and seismic load simulation, and data-driven performance evaluation methods. Through the construction and optimisation of the BIM model, not only is the design accuracy improved, but the intelligent and dynamic optimisation of the design process is also realized, especially in the application of seismic performance prediction and structural optimisation. The material utilisation rate of 23.5% shows a high resource utilisation efficiency, while 87% of the building structures meet the design seismic standards. When considering different optimisation schemes, a 54.8% improvement in seismic performance was recorded. However, a 12.9% increase in cost affected the final decision. The optimized scheme exhibited a 68.4% improvement in seismic stability, while a 91% shortened construction period, indicating that the optimized design improved performance and significantly improved in time. A good balance is achieved between the 34.7% increase in seismic effect and the 77.2% cost saving, indicating the critical role of BIM technology in optimisation design.
