HanGi IT AStrutTie v2017-AMPED

AStrutTie is a strut-tie model analysis/design software for concrete members with disturbed stress region(s). It enables users to design corbel (bracket), abutment/pier footing, bridge pier coping (pier cap), frame corner, anchorage zone, simply supported/continuous deep beam, beam-column joint, PSC box, etc. The software supports U.S (ACI 318, AASHTO LRFD) and Europe (EuroCode 2) codes and specifications.
