High Order Single Step Substructure PseudoDynamic Testing Algorithm

Abstract:

Based on the study on the high order singlestep pseudodynamic testing algorithm,the high order single step algorithm featuring unconditionally stable good algorithm damping properties,a lack of transcendental phenomenon,and Δt5 of truncation error is applied to substructure pseudodynamic testing,and then the high order single step substructure pseudodynamic testing algorithm is proposed.The feasibility and superiority of the algorithm are verified with the numerical simulations of the substructure pseudodynamic testing algorithm comparison and the testing results of the fullscale framesupported reinforced concrete shortlimb masonry shell wall structure.
