Influence of Different Types of Infill Walls on the Hysteretic Performance of Reinforced Concrete Frames

To study the influence of masonry infill walls on hysteretic performance reinforced concrete frames, a cyclic experiment was conducted for three two-story and two-span frame structures, including one without two frames with walls. Whether were constructed in type infilled material main parameters test. The major results reveal that: clearly changed mechanical mechanism structure at early stage loading, magnified stiffness horizontal bearing capacity structure, enhanced energy dissipation but reduced deformation structure. In later would no longer work as gradually failure walls, above approach empty Moreover, initial stiffness, capacity, clay hollow bricks highest among specimens. But due to strong diagonal bracing effect, damage top columns beam-column joints serious, yield displacement significantly, shear occurred prematurely, which showed poor ductility. However, relatively soft aerated lightweight blocks better
