Non-Destructive Testing for Structural Condition Assessment

Non-Destructive Testing for Structural Condition Assessment

Structural Condition Assessment usually refers to the process of collecting observations and data about the existing condition of the structure through systematic and scientific methods. According to the Professional Engineers Ontario Guideline for “Structural Condition Assessment of Existing Buildings and Designated Structures” (PEO, Nov 2016), structural condition assessment are within the practice of professional engineering. This primarily fall in two categories: Preliminary assessment Detailed condition assessment Depending on the objectives… Read More »Non-Destructive Testing for Structural Condition Assessment

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 developed countries are nearing the end of their initial service life design. According to the… Read More »Common Defects in Bridge Structures

Heating Concrete Cold Weather Concreting FPRimeC Solution

Protecting Concrete in Cold Weather

Protecting concrete in cold weather is a continuous challenge for concrete contractors and site supervisors. Placing concrete in the cold weather condition requires special preparation and protection. All necessary precautions should be taken in order to to alleviate the negative impacts of cold weather. Special curing and protection is required in most cases.  In my previous article, we reviewed what is considered cold for concrete construction, and what should be… Read More »Protecting Concrete in Cold Weather

Cold Weather Concreting

Precautions for Cold Weather Concreting

Extreme cold weather conditions can significantly affect the quality of concrete, as well as its mechanical properties. In cold weather concreting, one should make sure that all the negative impacts of low ambient temperature are appropriately alleviated by taking the necessary precautions. In this article, we will review important steps that can ensure you will get the quality you are looking for. But first, let’s see what cold temperature is… Read More »Precautions for Cold Weather Concreting

How to Evaluate Compressive Strength of Concrete

What is the best method for the measurement of compressive strength of concrete? Testing cylinders and cubes in compression is the most convenient and well-known method for measuring the strength. The main question is if one can design and develop a method that can measure the strength faster, easier, and more accurate? Can all the advancements in sensor technology and better understanding of the development of concrete microstructure can help… Read More »How to Evaluate Compressive Strength of Concrete

inspection and evaluation of sructures

Ontario 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.

Structural Effects of Corrosion

Structural Effects of Corrosion

You may think that corrosion in structures is a just a durability-related issue in the first glance. Well, that is far from the truth. In fact, corrosion can directly affect mechanical and structural properties of components. Corrosion can affect the global response of the structure. In this article, we will review some of the main structural effects of corrosion on steel structures and reinforced concrete structures. Before we begin, let’s… Read More »Structural Effects of Corrosion

shear wall

Major Techniques for Modeling Shear Walls

Modeling Shear Walls Modeling shear walls have changes during the last two decades. Analyses techniques have moved from linear static to nonlinear dynamic, enabling more realistic modeling and simulations. Different approaches for modeling shear walls span from macro models such as modified beam-column elements, to micro models such as 3D finite element models. An appropriate modeling technique should: Be capable of predicting the inelastic response   Incorporating important materials characteristics Simulate… Read More »Major Techniques for Modeling Shear Walls
