[more ▼] The wall collapse-initiated disaster in infilled reinforced concrete (RC) frame structures has been increasingly concerned by research community recently. This paper studies the seismic performances of a bare RC frame and three RC frames infilled by different lightweight materials in full scale under cyclic loads, including hollow bricks, gypsum blocks, and autoclaved lightweight concrete panels. The main studied performances include lateral resistance capacity, stiffness, wall damage, ductility, and energy dissipation capacity of the frames. Based on the experimental results and literature research, this paper discusses ideal infill materials for RC frame structures and skeleton curve of the frames.

[more ▼] This paper discusses and quantifies the minimum requirements of walls and tie-columns in confined masonry (CM) buildings located in earthquake-prone regions. A research database including 238 damaged CM buildings obtained from the 2008 Wenchuan earthquake survey is established and comprehensively examined. The requirements of masonry walls in CM buildings are discussed, and a simplified tie-column density index is proposed for evaluating the potential damage of the structures. Besides, the minimum requirements of reinforced concrete tie-columns and their maximum allowable spacing in CM buildings at different seismic intensity zones are discussed.
