Introduction Fiber reinforced polymer (FRP) composite systems, consist of fibers embedded in a polymeric matrix. They are used for Flexural and Shear strengthening of reinforced concrete (RC) members. Since the late 1980s,...

When we see amazing and efficient structures around us but we often forget about some of the biggest failures in construction. We can learn a lot as civil engineers from these...

This video tutorial by Dr. Structure provides an insight of support settlement. Support Settlement is quite common in bridge structures where support settles after construction of bridge if proper soil investigation...

Influence Lines for statically determinate beams This video (given below) by Dr. Structure explains the influence line of moments considering the case of statically determinate beams. Influence lines are great tool to determine...

Every substance in concrete having average particle size less than 125 microns in known as "powder". If we examine finely grounded powder when it comes in contact with water, we will see...

ITZ ITZ in civil engineering terminology is known as interfacial transition zone or intermediate transition zone. This is the phase present in concrete where two different phases meet with each other. As...

The following "ten principles for engineers" are taken from Abeles (reference at the end) and are applicable to any endeavor that the engineer is called upon to undertake. You cannot have everything....
Analysis of statically determinate beams

This video by Dr. Structure explains the procedure to analyse statically determinate beams. The concept though very basic is essential to understand. What is a statically determinate beam? Beam is statically determinate if...

Durability Durability of concrete can be defined as its ability to resist weathering action, chemical attack, abrasion or other process of deterioration and hence retains its original shape, dimension, quality and serviceability. Deleterious...

  Spalling Spalling is considered as one of the most complex and poorly understood phenomenon occurred at high temperatures. (Khoury 2000; Tenchev and Purnell 2005) Mostly it is assumed that this phenomenon occur...
bendable concrete

Bendable Concrete? What? How is it even possible? We all know that concrete is a brittle material poor in tension so how can it bend? ConFlexPave answers the questions! Nanyang Technological University...

shear force and bending moment diagrams are graphical interpretation of shear and moment across the member. In this tutorial by Dr.Structure, We will learn how to draw these diagrams. Using these diagrams...
