The importance of loading is quite obvious to everyone. The larger the loads are the stronger the cross section must be. However in simple lessons such as statics loads are always given, in reality loading comes with uncertainties. In simple words we need to design for the worst possible loading condition which might never happens […]
LRFD and ASD might be two confusing term for some of you. To be honest, when I was in university I never found out what are the meaning of these technical terms. In this article I want to explain them in really simple terms. ASD is an abbreviation for Allowable Stress Design. LRFD refers to […]
P-Δ effect and P-δ effect are usually two confusing terms for occasional ETABS users. In this article I am going to explain them in details and in our ETABS video coarse you can also learn have to apply them in the software. P-Δ effect is one of phenomenon that influence on the behavior of the […]
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 […]
