Eriksson Beam allows the engineer to quickly analyze and design precast/prestressed concrete beams in accordance with ACI 318-. All types of horizontal precast members can be designed, including double tees, inverted tees, spandrels and hollow core slabs. Also included are sections that require a principal axis analysis, such as stadium risers. Reinforcement can be any combination of prestressing strand, rebar, and mesh. Multiple holes in both beam webs and decks can be modeled. A general purpose polygon editor is included for the design of unusual cross sections.
