simdesign.rcmrf.bnsm.dp02.beam

This module provides the beam class implementation for the DP02 model in the BNSM layer.

class simdesign.rcmrf.bnsm.dp02.beam.Beam(design, bondslip_factor, load_factors, cyclic_model=False, cracked_section=False)[source]

Bases: BeamBase

Beam implementation for the DP02 model.

This class extends BeamBase with a force-based beam-column formulation and lumped plasticity end hinges following the modelling strategy in O’Reilly (2016).
