The key difference between prefabricated structure and cast-in-place structure is the connection of components. The comprehensive reliability of the connection directly determines the overall performance of the structure, and also affects its application scope in the building structure. It is particularly important to select the appropriate beam-column connections in the construction. In recent years, with the continuous development of precast concrete structure, a large number of precast beam-column connections have been invented. However, in view of different construction environment, construction cost and building function requirements, the selection of precast beam column connections is often difficult to choose. Therefore, this paper is based on the Analytical Hierarchy Process (AHP) evaluation model, combined with the evaluation index of the precast concrete beam-column connections, to provide a scientific method for selecting suitable precast beam-column connections for engineering construction.
