Use of Diaphragm Properly in Etabs Explained in Depth
admin
First we need to know about Diaphragm Constraint, Rigid & Semi-rigid diaphragm. Lets start- Diaphragm Constraint: We know what are restraint joints (Supported individually) & constraint joints (Connected to each other so their translation & rotation happen together). Diaphragm constraint ...
Mat or Raft Foundation Design Aid
admin
A raft foundation, also called a mat foundation, is essentially a continuous slab resting on the soil that extends over the entire footprint of the building, thereby supporting the building and transferring its weight to the ground. A raft foundation ...
Inclined or Raked Column Design
admin
The main secondary effect of having inclined columns is that they introduce a horizontal component of the axial load into the beams/floor slabs at each level, so you need to design for these forces.Also, you need to be careful about ...
Stair Modeling Clarification in Etabs as it may consider a Stair Slab as wall area object.
admin
As per one case study, Etabs considers Slabs maintaining slope more than 3.63/10 as Wall area object. Whatever it considers that is not our concern, concern is-we have to be careful while using stiffness modifier for slab & wall (as ...

Suppose you have to tighten a nut of your bicycle and I tell you to do it by hand, will you be able to do it? No of course not, but what if I give you a wrench with a ...
What is the difference between Membrane and Shell?
admin
This is a global differentiation in all the finite element software. Membrane elements are used to represent only inplane stiffness of members. It acts like the bedsheet on your bed. The bedsheet does not have any kind of bending stiffness ...
Why does required column reinforcement in the upper story appear higher than the lower story? And What are the solutions?
admin
First we need to know about Unbalanced Moment. Unbalanced Moment: Gravity loads on columns consist of an axial load and moments about both axes where the column design moments are caused by unbalanced loading. Such moments are created when there is an ...
History of Structural Engineering

Structural engineering dates back to 2700 B.C.E. when the step pyramid for Pharaoh Djoser was built by Imhotep, the first engineer in history known by name. Pyramids were the most common major structures built by ancient civilizations because the structural form ...
One Way Slab
admin
One way slab is a slab which is supported by beams on the two opposite sides to carry the load along one direction. The ratio of longer span (l) to shorter span (b) is equal or greater than 2, considered as One way slab because this slab will ...
