What are Floating Columns? Are they Advisable?

A floating column is also called as hanging column or stub column, which unlike regular column rest over the beam element of the structure. The regular column is designed to transfer the load to the foundation or to the column below and then to foundations. But a floating column will not be involved in the direct transmission of the load.

What is Punching Shear? Punching Shear in Flat Slabs

7/17/2014 · What is Punching Shear? Punching shear is a type of failure of reinforced concrete slabs subjected to high localized forces. In flat slab structures this occurs at column support points. The failure is due to shear. This type of failure is catastrophic because no visible signs are shown prior to failure.

Detailing Concrete Columns

Detailing Concrete Columns D esigners of concrete structures are typically concerned about the final design and not necessarily about how a specific concrete element gets built. In other words, engineers tend to avoid issues that are traditionally contractor “means and methods.” Yet, decisions made during the design process can have

Steps in Designing a Transfer Floor

Design of reinforced concrete transfer floors, although routinely performed by structural design engineers, is a very challenging task. The transfer floors are commonly used in multi-storey buildings, and they are major structural elements carrying a number of floors. Normally the entire building, 10 to 15 levels, is carried by a transfer slabs.
