Abstract
In order to study the seismic stress performance of the reinforced concrete frame assembly fly ash plate sandwich polyurethane composite wall insulation system (FW). In this paper, 2 bay single-layer single-span hollow fly ash plate sandwich polyurethane in filled frames were tested under low cyclic horizontal loadings with different ratio of high to width and different stiffness frame . Based on the experiment, the damage process, failure mode, load carrying capacity are studied. The interaction between the fly ash plate sandwich polyurethane infill walls and the overall frame of constraint system are investigated. The results indicate that the bearing capacity has little related to height-width ratio of wall; sandwich polyurethane wall panels and frame has good integrity and energy dissipation capacity; the ratio of high to width smaller, ductility of wall is better . After study the failure pattern of the specimen, we know that the bearing capacity of fly ash powder polyurethane thermal insulation wall is not accord with formula of seismic shear of not bearing masonry.
