要旨 The authors have developed a computationally efficient procedure to comprehensively understand failure mechanisms of reinforced concrete structures. This paper presents numerical applications to a two-span continuous beam with external prestressing tendons and reinforced concrete T-shape bridge pier with prestressing tendons under eccentric loading. Concrete material is represented by a rigid-body-spring model with random geometry. Reinforcing materials are explicitly modeled using a beam- and linkage-spring. The spring network models provide useful predictions such as loading capacity, crack pattern, failure mode and stress increase of prestressing tendon.
