The effects of the load-displacement curves of the new-type precast fabricated concrete diaphragms were studied, through numerical simulation analysis of it under in-plane force. The concrete strength, the number and spacing of the connector, the strength of the connector bending reinforcement, boundary beam longitudinal reinforcement strength, boundary beam stirrups strength are taken as parameters. On the basis of analysis, the recommendations on the New-Type Precast fabricated Concrete Diaphragms are proposed for design and construction.Keywords: precast fabricated; diaphragm; in-plane
