Design on the Prestressed Concrete Frame Beam-column

A bidirectional ribbed concrete beam slab structure was widly adopted for the upper space of industrial buildings. To maintain ample space and minimize the presence of conventional columns, a bidirectional prestressed concrete beam is often employed. The intersection node of the prestressed concrete frame beam column was characterized by a high density of steel reinforcement, significant structural loads, and complex construction requirements. To ensure the quality, safety, and progress of prestressed frame beam-column intersection nodes during construction, this article proposed a new technology for constructing such nodes, which includes setting the tensioning and haunching ends of nodes at different positions, using ABAQUS finite element software to optimize the design of cross-sectional dimensions, conducting stress analysis simulations.
