MASONRY-INFILLED RC FRAMES SUBJECTED TO COMBINED IN-PLANE AND OUT-OF-PLANE LOADING

摘要: The structural responses of infilled frames subjected to combined in-plane and out-of-plane loadings are usually analyzed by separately applying loads. interaction effect loads on the behavior is ignored; thus errors in predicting actual force-transfer mechanisms modes failure structures can be incurred. To solve problem, this paper presents a discrete finite element modeling technique, which employs damage-based cohesive crack representation fracture masonry infills, followed study anchored unanchored reinforced concrete (RC) interactive analysis indicates that under loading diagonal compressive thrust masonry-infill walls, induced lateral acts may reduce load capacity RC frame up 50% cause buckling infill walls. On other hand, anchorage effectively prevent separation walls from bounding provide stabilizing forces against buckling.
