Experimental Investigation and Numerical Analyses on Cyclic Behavior of the Prefabricated Concrete Frame Infilled with CFS-CLPM Composite Walls

A novel CFS composite wall filled with cement-based lightweight polymer material (CFS-CLPM wall) has been proposed and proven to have excellent architectural mechanical performance. To promote its application in prefabricated concrete (PC) frame structures, two full-scale specimens were designed tested under cyclic loading investigate the failure mode, hysteretic response energy dissipation of PC infilled CFS-CLPM wall. The experimental results indicated that walls can significantly improve lateral behavior terms load capacity, elastic stiffness while slightly reducing ductility because infill-frame interaction. Subsequently, finite element (FE) analyses for developed verified against results. force-transferring mechanisms between revealed by analyzing stress distributions. parametric demonstrated influential parameters resistances structure strength CLPM, span-to-height ratio thickness walls. Finally, a formula considering contribution was predict structures. this study could provide basis
