Dead Loads

Dead Loads are referred to gravity loads of constant magnitudes and fixed positions that act permanently during the lifespan of the structure. it includes the weights of the structural members itself and that the material and equipment permanently attached to the building. To remain accurate, the weights of permanent equipment, such as air-conditioning systems, should […]

Shear Wall

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

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 […]

light weight concrete

Light weight concrete can be used for both insulation purposes and construction of structural members. Using lightweight coarse aggregate can reduce the density of the concrete mixture to between 90 to 115 lb / ft³ (1440 to 1840 kg/m³). in other words, it is much lighter in comparison with the density of normal concrete, which is between […]

Loads Caused by Construction

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 […]
