With rapid improvement of computing technology, nonlinear inelastic analysis methods are commonplace and permitted in new design code versions of AISC-LRFD, AASHTO, etc. However, their applications on practical design of steel structures are still very limited due to excessive computational efforts. To overcome this problem, we develop a novel software, named as PAAP3D, in this study. PAAP3D is based on the plastic hinge approach that requires only one or two elements for modeling a frame member so computation time is efficiently reduced. The nonlinear inelastic truss and catenary elements are also implemented in PAAP3D that allows the use of this
software for analysis of truss struc...
