Lessons4civil aims to provide high quality video lessons for civil engineers in a wide range of domains such as numerical modeling, geotechnics, land surveying and structural design. Our workshops are specially structured to bridge the gap between industry requirements and academic lessons. We try to engage and motivate students to open up their mind.
قانون نیوتن شاید اولین چیزیست که یک دانشجوی مهندسی عمران در اولین درسهای استاتیک با آن برخورد میکند. به زبان ساده در علم استاتیک مربوط به اجسامیست که در حالت تعادل هستند. حالت تعادل یعنی اینکه اجسام هیچ حرکتی ندارند و ساکن میباشند. اگر به اطراف خودتان نگاه کنید متوجه خواهید شد که اکثر سازه […]
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 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 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. 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 […]
