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.
How should I position the shear wall? These is a question that comes up all the time among structural designers. To answer this question let me clarify what shear walls do. Shear walls provides extra stiffness to the structure to resist against lateral loads. So the dimension of shear walls must be large enough to […]
Live loads are applied temporary during the lifespan of the structure. they are usually changeable and dynamic. Some examples of live load are the weight of occupants, furniture, equipment and vehicle traffic. Live load can be either concentrated or distributed. However their magnitude are variable, design codes define equivalent loads for different cases. Since their magnitude is not constant, the […]
In addition to usual loading, some loads are created and applied to the structural members during the installation and construction processes. These loads, which are mainly gravity loads, must be predicted in designing in order to provide a safe construction. In the following paragraphs, we explain some of these kinds of loading. Prefabricated sections and […]
Rigid body is a basic concept in statics problems. When you study in university, the curriculum has been designed from the simplest coarse to the most advanced one. Simple coarse such as statics are based on some simplification which are not eligible in more complex coarse such as mechanics of material. For example in statics […]
One important engineering judgement you need to make in ETABS, is about connection points. As I explained several times in my video coarse in reality there is no ideal joint similarly none of the connections are completely fixed. So being joint or fixed is just a simplification assumption. To make this decision we need to […]
