CE 537, Spring 2011 Analysis of Combined Axial and Bending 1 / 8 Loads on Columns Axial loads and bending moments both cause normal stresses on the column cross-section. We analyze the normal stresses from these combined loads in the same way that we analyze the normal stresses due to bending only in a beam, with two exceptions. 1.

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.

"Eurocode 2: Design of concrete structures - Part 1-1: General rules and rules for buildings" (from now on referred to as EC2) defines rules for design for shear punching. The method in EC2 is based on experiments, and most of the formulas are therefore empirical. The next sections will briefly present the calculation method used in EC2.

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 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
