Experimental Study on the Seismic Behavior of a Modified Adobe-Brick-Masonry Composite Wall with a Wooden-Construction Center Column

Damage to adobe constructions might occur due a long wall and lack of effective restraint in the middle wall, causing it collapse under an earthquake. Aiming at these problems, technology for improving seismic performance modified adobe-brick-masonry composite with wooden-construction center column is proposed. It uses mud, wooden column, steel-wire mesh, nylon ropes reinforce wall. On this basis, four specimens one specimen were subjected proposed quasistatic, cyclic in-plane loading tests study their failure modes indicators. The results show that all walls shear failure. difference had horizontal cracks middle, whereas largely intact. Moreover, relied on mud improve bearing capacity each They tie materials form second line defense would increase ductility residual area. As result, phenomenon caused damage stiffness degradation was lessened.
