Earthquakes in Italy

Why Earthquakes Hit Italy and How to Reduce The Risk?

An earthquake of magnitude 6.6 struck the center part of Italy (6 km from Norcia) for the second time since earthquake in Aug 2016. The earthquake is believed to be the strongest to hit Italy since 1800. But why is Italy so prone to earthquake? In this brief note, we will review some facts about Read more about Why Earthquakes Hit Italy and How to Reduce The Risk?[…]

Structural Effects of ASR on Concrete Structures

Extensive mapped crack on the surface of concrete structures can be a scary observation for public, or even most structural engineers. There is a common belief among material and structural engineers that the Alkali Silica Reaction (ASR) is always harmful for a concrete structure. It is scary to drive under a ASR affected bridge. Despite Read more about Structural Effects of ASR on Concrete Structures[…]

How to Use GPR for Evaluation of Concrete Piles

How to Use GPR for Evaluation of Concrete Piles

Detection and evaluation of unknown foundations of old construction, particularly buried piles can be a big challenge, because: * No structural drawing is available. * The access to the piles is difficult, if not impossible. * The traffic or operation of (or over) the superstructure can not be interrupted. Certain non-destructive methods have been developed over years Read more about How to Use GPR for Evaluation of Concrete Piles[…]

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[…]

Maturity Method for In-Place Strength Measurement

In this article, we will investigate the use of maturity method for in-place strength measurement. We will review the concept behind the maturity technique, and the most common practices. Later, we will describe the benefits and limitations of this method for in-place strength prediction. In the last part of this article, we will review and examine Read more about Maturity Method for In-Place Strength Measurement[…]

Non-Destructive Evaluation of Unknown Foundations

Non-destructive evaluation of unknown foundations and piles has gained interest among engineers and researcher over the past few years. Latest research show the effectiveness of these methods in investigating the depth and quality of existing piles, as well as in the quality assurance of new construction. Piles are structural members made of timber, steel, or Read more about Non-Destructive Evaluation of Unknown Foundations[…]

Inspection and Evaluation of Structures

Inspection and evaluation of RC structures is the best method to evaluate the condition of infrastructure facilities. Inspection is considered the first step in any structural maintenance program. Inspection can be as simple as a recording visual condition of the structure or a more complicated one, such as a forensic study of an incident or catastrophe in Read more about Inspection and Evaluation of Structures[…]
