Axial stress, Axial deformation

Axial stress is a topic that is very important in design of structures. In simple words, if I apply a force exactly normal to cross section and exactly at the center line, this kind of loading is called pure axial loading. That means there is no bending moment and no shear force. In such cases, […]

Concrete strength reduction due to firing

Concrete strength reduction due to firing  has been always a permanent concern for structural engineers. Most of materials, including concrete lose their strength if their temperature increases. In this article we mention several important tips about concrete to maintain the overall safety of structures in fire accidents. Abstract The first reaction of concrete to short term […]

Concrete Volume Estimation

Concrete volume estimation and how to order it  are two topics that all civil engineers need to know about. These details may seem trivial but they can become a nightmare for young newly employed civil engineers. So let’s clarify it. In most of countries, to order concrete mixture you need to request it by filling […]

Concrete spalling

Concrete spalling is one of problematic damages for concrete members. As you can see in the figure below, when it happens, concrete member becomes more expose and vulnerable to erosion. As a result, it is highly important to find out what causes spalling, and how can we prevent it. Causes: Generally, we can mention three […]

Floor functionality does affect on its design.

Floor functionality does affect on its design. No matter how simple this topic seems at the first look, but these kinds of questions comes up all the time for junior engineers and students. So clarifying every simple aspect of civil engineering is what we do in our articles. In this article, you will understand what […]
