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 […]
Defects in construction We all know humans are not immune of making mistakes. Throughout our video coarse, whenever I find the opportunity I try to introduce some common mistakes hoping other engineers do not make them again. In this article, construction defects are categorized and discussed briefly. Generally there are 3 sources of defect including […]
As it is obvious, structures are always subjected to lateral loading such as wind load or earthquake. As a result the structure must be supported against lateral loading prevent any excessive deformation. A braced frame is a structural system to provide enough lateral stiffness for the building. These members are generally made of steel and have a significant […]
What are a Shear Wall? Buildings are always subjected to lateral loading. To restrict the lateral deformation of building, some members must be designed to counteract the lateral forces in each directions. One technic is to design shear walls. In simple words, a shear wall is a structural member with high bending stiffness that strengthen […]
Analysis methods in ETABS is an interesting topic. ETABS covers 6 different analysis methods which are listed below. Each method has its own advantages and limitations. So in this article I am going to briefly introduce their differences and for comprehensive information about this topic you can watch a video lesson. Linear static analysis Linear […]
