Advances in Constructional Engineering

The addition of elevators to existing buildings has become an important measure to improve the travel conditions of residents in old communities and buildings. However, the addition of elevator shafts often faces multiple challenges such as space constraints, structural issues, and cost limitations. This paper mainly explores how to design the elevator shaft addition for existing buildings using topological optimization technology to achieve a balance between maximum space utilization, structural safety, and construction economy. By analyzing the structural layout of buildings, architectural functional requirements, and elevator shaft design specifications, combined with topological optimization theory, an optimization scheme is proposed to effectively reduce the design difficulty and cost of shaft addition. The feasibility and practical application effect of this method are verified through numerical simulation and case analysis.
