Concrete Shear Wall Construction
Buildings with cast-in-situ reinforced concrete shear walls are widespread in many earthquake-prone countries and regions, such as Canada, Chile, Romania, Turkey, Colombia, the republics of the former Soviet Union, etc. This type of construction has been practiced since the 960s in urban regions for mediumto high-rise buildings (4 to 35 stories high). Shear wall buildings are usually regular in...
متن کاملStructural Engineering Forensic Evaluation of Misdiagnosed Concrete Masonry Wall Cracking
Given that concrete masonry walls are expected to experience shrinkage combined with thermal expansion and contraction, and in some cases even carbonation, throughout their service life, cracking is to be expected. However, after concrete masonry walls have been placed into service, originally anticipated and accounted for cracking is often misdiagnosed as a structural defect. Such misdiagnoses...
متن کاملEffect of Reinforcing Bar Contamination on Steel-Concrete Bond During Concrete Construction
Synopsis: During concrete construction, form oil, bond breaker, concrete splatter and other types of contaminants often contaminate reinforcement. Current specifications and quality control measures require the removal and clean up of these contaminants before the placement of concrete due to a concern of a reduction in bonding capacity. This is costly, labor intensive, and may not be necessary...
متن کاملCorrosion of Reinforcing Bars in Concrete
The causes and mechanisms of corrosion of reinforcing bars in concrete are described in terms of the practical issues as well as the electrochemistry. The parameters affecting corrosion are (i) the ingress of aggressive species, such as chlorides, which break down the protective film on the reinforcing bar and (ii) the amount of those species necessary to do so. The former is largely controlled...
متن کاملDetection of Bricks in a Masonry Wall
Laser scanning is being increasingly applied in the documentation of buildings and archaeological sites. The documentation process sometimes involves making an inventory of bricks in walls. This paper proposes an automatic/semi-automatic segmentation method for detecting bricks in walls, in particular masonry walls. In developing the detection method the problems with detecting bricks in a 3D p...
