Common Defects in Bridge Structures

  • by

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

Protecting Concrete in Cold Weather

  • by

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

How to Evaluate Compressive Strength of Concrete

  • by

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

Share on linkedin Share on facebook Share on twitter Share on telegram Share on whatsapp Share on email Corrosion of steel reinforcement is often investigated in the context of the durability performance of the structure; however, corrosion can equally impact the structural performance. Steel corrosion may result in reduced flexural capacity (loss of rebar cross section), reduced bond, and limited ductility. In this article, we will review some of the… Read More »Structural Effects of Corrosion

Major Techniques for Modeling Shear Walls

  • by

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

Why and When to Use Concrete Piles?

  • by

Concrete Piles and drilled shafts are an important category of foundations. Despite their relatively high cost, they become necessary when we want to transfer the loads of a a heavy superstructure (bridge, high rise building, etc.) to the lower layers of soil. Another reason for choosing a pile foundation is the condition and quality of soil layers. Based on how they transfer the load into the subsoil, piles can be… Read More »Why and When to Use Concrete Piles?
