the design of ductile reinforced concrete structural walls

Dec 30, 2004 For reinforced concrete (RC) members, this curvature depends on the tensile strain of the reinforcement and the compressive strain of the concrete. As concrete is a brittle material with little ductility, RC members achieve ductility and adequate deformation capacity mainly through the tensile straining or yielding of the reinforcement. masonry walls, floors and roof of reinforced concrete (reaching 2.92 GJ.m-2). Finally, they calculate the embodied energy in homes built with reinforced concrete structure and masonry walls, coming to 4.21 GJ.m-2. Also in India, Chel Tiwari (2009) examined constructions very

reinforced concrete crushing with a cbe 20 simex

The Mw 8.8 earthquake in 2010 in Chile provided valuable information regarding the damage and potential design code changes for reinforced concrete (RC) structures. Many modern RC buildings suffered severe damage, mainly in the form of concrete cover spalling, followed by longitudinal boundary bar buckling and concrete crushing. In the design of reinforced concrete multistorey buildings, in which lateral load resistance has been assigned to structural walls, the emphasis should be on a rational strategy in the positioning of walls and the establishment of a hierarchy in the development of strengths to ensure that in the event of a very large earthquake brittle failure will not occur.

investigation of damage in reinforced concrete shear

Mar 28, 2012 Observed wall damage in recent earthquakes in Chile and New Zealand, where modern building codes exist, exceeded expectations. In these earthquakes, structural wall damage included boundary crushing, reinforcement fracture, and global wall buckling. Recent laboratory tests also have demonstrated inadequate performance in some cases, indicating a need to review code provisions, reinforced concrete code provisions, except boundary element confinement was not required. The 2010 Mw 8.8 earthquake caused serious damage to many of these buildings, including crushing/spalling of concrete and buckling of vertical reinforcement, often over a large horizontal extent of the wall (Fig. 1).
