Through the analysis of keyword frequency and centrality (Table 1), the keyword with the highest frequency is “seismic performance”.

With the development of precast buildings, the study of building structural performance has become a focus, among which the analysis of node performance of precast concrete structures and the mechanical performance analysis of the overall structure under earthquake action are becoming increasingly important.

Using numerical simulation methods to analyze and evaluate the beam column joints of precast buildings can predict their mechanical behavior and structural performance.

Therefore, the relationship between “beam column nodes” and “numerical simulation” is relatively close.

In addition, the seismic performance of buildings can also be evaluated through hysteresis curves to assess the stiffness, energy dissipation, and residual deformation of the structure, thereby determining its seismic performance.
