When the external loading is uniaxial, that is S1= a positive or negative real value, S2=S3=0, then all failure theories predict the same as that has been determined from regular tension/compression test. 4.1.

8. STRENGTH OF SOILS AND ROCKS

In the case of concrete, the compressive strength is the most commonly measured strength parameter and this is also true of rock specimens. For the uniaxial or unconfined compressive strength test a right circular cylinder of the material is compressed between the platens of a testing machine as illustrated in Fig. 8.1. ...

Design of Columns

1 Design of Columns Introduction According to ACI Code 2.2, a structural element with a ratio of height-to-least lateral dimension exceeding three used primarily to support compressive loads is defined as column. Columns support vertical loads from the floor and roof slabs and transfer these loads to the footings.
