Why We Need Structural Health Monitoring?

Why We Need Structural Health Monitoring? Owners and maintenance managers of capital-intensive assets are looking for cost-effective and reliable inspection and monitoring solutions to ensure safety and reliability of these structures. Modern design codes are now looking in a much longer service life. For example, The Canadian Highway Bridge Design Code (S6-14, 2014) considers a Read more about Why We Need Structural Health Monitoring?[…]

the future of bridge inspection

The Future of Bridge Inspection

The Canadian Highway Bridge Design Code (S6-14, 2014) considers a service life of 75 years for newly constructed bridge. What does this mean in engineering terms? It means that the bridges of the future should have satisfactory performance, both durability and structural, during the proposed life-cycle. This can be quite challenging when we look closely; Read more about The Future of Bridge Inspection[…]

How To Test Concrete Using Impact-Echo Method

How to Test Concrete Using Impact-Echo Method?

In this article, we will briefly present and discuss Impact-Echo (IE) method for testing concrete structures. The concept behind the technique will be reviewed. We will also study the applications and limitation of the IE method and How to Test Concrete Using Impact-Echo Method.  The test method was adapted as a standard test procedure by the Read more about How to Test Concrete Using Impact-Echo Method?[…]

Non-Destructive Evaluation Bridge Abutments

How to Evaluate Bridge Abutments?

In a bridge structure, abutment refers to the substructure unit which supports the end of the structure (bridge span) and retains the approach fill (see Ontario Structure Inspection Manual). Abutments are commonly made of mass concrete, reinforced concrete, or wood. Usually, abutments consist of a number of components: + Foundation + Abutment wall + Ballast wall + Read more about How to Evaluate Bridge Abutments?[…]

Common Defects in Bridge Structures

The collapse of Ponte Morandi in Genoa, Italy (read more) and Florida International University pedestrian bridge (read more) have raised concerns about the safety and reliability of existing and new bridge structures. common Defects in bridge structures can affect the overall safety of the bridge structures. Different deterioration mechanisms can lead to major defects. Exiting infrastructure in Read more about Common Defects in Bridge Structures[…]

Estimate Strength of Concrete Using NDT Methods

How To Estimate Strength of Concrete Using NDT Methods?

In this article, we will briefly review how to Estimate Strength of Concrete Using NDT Methods. Compressive strength of concrete is by far the most important property of concrete. It represents the mechanical properties of concrete; for example, the 28 days compressive strength of concrete cylinders is the key parameter in most design codes (ACI 318-14, CSA Read more about How To Estimate Strength of Concrete Using NDT Methods?[…]

Corrosion Monitoring of Reinforced Concrete Structures

A corroded structure (whether it is a bridge, or a jetty, or a simple ramp) could be scary for many people. Imagine yourself driving along the Gardner Express (Downtown Toronto), or the highway 40 (Montreal), and all of a sudden, a piece of concrete falls onto your car, breaking the windshield. Feels scary? Indeed! A Read more about Corrosion Monitoring of Reinforced Concrete Structures[…]

Condition Survey for Bridge Decks

4 Methods of Condition Survey for Bridge Decks

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 for structural health monitoring

Acoustic Emission Monitoring for Civil Infrastructure

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[…]

inspection and evaluation of sructures

Remarks on Ontrio Structure Inspection Manual

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[…]
