Abstract

Prefabricated concrete frame structures are widely used in modern construction due to their high construction efficiency, environmental friendliness, and other advantages. However, the seismic performance of their joints remains a key issue restricting their development. This paper focuses on the optimization design of seismic performance for prefabricated concrete frame joints and proposes a joint construction optimization method based on intelligent algorithms, aiming to enhance the bearing capacity, ductility, and energy dissipation capacity of joints under seismic actions. Through comparative analysis of finite element simulations and test data, the effectiveness of the optimized model is verified, and the influence laws of different construction forms on the seismic performance of joints are discussed. The introduction of intelligent optimization strategies can significantly improve the scientificity and reliability of joint seismic design, providing a new technical path for the seismic design of prefabricated concrete structures.
