Exposed Concrete Decks suffer from various deterioration mechanisms; i.e. freezing and thawing, corrosion. The most significant consequence is the delamination of concrete, which could eventually trigger other damage mechanism, such as corrosion. The maintenance of deck slabs is quite challenging mainly because it normally involves large areas; In many cases, closing the deck to traffic Read more about 4 Methods of Condition Survey for Bridge Decks[…]
Acoustic Emission is referred to the radiation of acoustic waves in solids as a result of damage or any irreversible change in its internal structure. Acoustic emission monitoring is well-known for its application in structural health monitoring of civil infrastructure. Structural Health Monitoring Health monitoring is a process of implementing inspection, evaluation, reaction, re-inspection and re-evaluation in Read more about Acoustic Emission Monitoring for Civil Infrastructure[…]
This article is a brief review over different aspects regarding the bridge structure inspection procedure specified in the Ontario Bridge Inspection Manual (OSIM). The inspection manual has been used for bridge inspections in Ontario since 1985 with major upgrades to the document in the year 2000. According to the bridge inspection manual (section 1.2.1), “the main goal of the structural Read more about Remarks on Ontrio Structure Inspection Manual[…]
Ontario Structure Inspection Manual The Ontario Structure Inspection Manual has been used for bridge inspections in Ontario since 1985. The manual underwent significant modifications in the year 2000 (OSIM, 2008). This FAQ provides general definitions and terminology used in the OSIM 2008.
Damaged Bridges are a major concern in the maintenance and operation of transportation infrastructure. Bridge structures in North America were mainly developed in the 1960’s and 1970’s and are rapidly approaching the end of their initial service life. Major mega cities in North America spend millions of dollars each year to keep these structures safe and Read more about How to Test Damaged Bridges?[…]
Ground Penetrating Radar (GPR) provides a cost-effective, nondestructive and reliable tool for scanning and imaging of sub-surface defects, voids, and objects. GPR was primarily developed and used in geophysics and geology for subsurface scanning and imaging. Since then, the method has been successfully adapted in many other disciplines including civil engineering. The multipurpose nature of Read more about What is Ground Penetrating Radar[…]
Have you ever imagined what would happen if highway bridges could speak?: “That I broke an arm? That I have a steel tendon ruptured? …” Well, they are not too far anymore. Last week, I had the chance to participate in a presentation by Jacques Cartier and Champlain Bridges Incorporated (JCCBI) in the GTA, and Read more about Intelligent Bridge Monitoring[…]
