Finite element analysis of seismic performance of assembled phosphogypsum-concrete combination wallboards
A numerical analysis model of assembled phosphogypsum-concrete combination wallboard was established by using large-scale general-purpose finite element software ABAQUS.Based on the verification of the accuracy of the finite element model,three groups of 10 specimens were designed to study the effects of the longitudinal reinforcement rate of the concrete frame columns,the opening rate of the wallboards,and the distribution of opening locations on the damage pattern and seismic performance of wallboards with different parameters.The results indicate that the stress pattern inside the wallboards is diagonal in the compression zone.Additionally,the structural load-carrying capacity increases with a higher longitudinal reinforcement ratio within a certain range.As the opening rate increases,the bearing capacity of the wallboard decreases significantly,while the ductility increases slightly.Symmetrical distribution of openings is preferred over asymmetrical distribution,and vertical distribution is preferred over horizontal distribution.
