Özet

Purpose: This study investigates nonlinear modeling parameters for precast concrete moment-resisting emulative-welded (MAB 3) connections.

Study design/methodology/approach: Numerical models representing the connection details of MAB 3 specimens were constructed using the lumped plasticity approach. Nonlinear hysteretic response curves as pinched asymmetric, the modified Ibarra–Medina–Krawinkler (IMK) deterioration model with peak-oriented, asymmetric bilinear Takeda, and multilinear models are employed to represent the moment-rotation response of beam-column connections.  These models are then analyzed using the Seismostruct program to simulate how they behave when subjected to cyclic loads.

Findings: The results of the analysis were used to evaluate performance measures such as ductility, damage levels, and energy absorption of the connections for different hysteretic response curves.

Originality/value: The results will provide important information for performance-based seismic design and assessment of precast concrete structures.
