Ultra-High Performance Concrete (UHPC)
admin
Ultra-High Performance Concrete (UHPC) is a cementitious, concrete material that has a minimum specified compressive strength of 17,000 pounds per square inch (120 MPa) with specified durability, tensile ductility and toughness requirements; fibers are generally included in the mixture to ...
Equilibrium Torsion & Compatibility Torsion
admin
Equilibrium Torsion Equilibrium Torsion occurs when the torsional moment is required to be in equilibrium and maximum torsional moment (Tu) cannot be reduced by redistribution of moments. In this case the torsion reinforcement must be provided to resist all of ...
Proper Rebar Placement in Construction Site
admin
We need to be careful about Rebar placement in construction site. We need to know which direction bar will be at bottom & which direction bar will be on top at the same layer of reinforcement. Placement of rebar depends ...
What is the difference between thin and thick shell?
admin
Shell problems generally fall into one of two categories: thin shell problems and thick shell problems. Thick shell problems assume that the effects of transverse shear deformation are important to the solution. Thin shell problems, on the other hand, assume ...
What is the mechanism for such structures?Are they safe?
admin
We generally see a large portion of Slab is overhanged in different structure. We raise question how such large cantilever is safe? We think really these are cantilever, but actually these are not. Their mechanism is different. See the following ...
Advantage of Hollow Section over I Section
admin
The only advantage of hollow section over I section is resistance against torsion. Most of the material is present away from center of mass of the section. To resist torsion we need maximum portion of material away from its center. ...
Types, Reasons & Prevention of Column Failures
admin
We know generally Columns are axially loaded members in structure. It carries compression force due to gravity loads of the structure. Column fails for different reasons. There are mainly three types of failures occur in columns. These are- 1.Compressive Failure ...
