The module only uses strength design for concrete.

All calculations are according to the referenced version of ACI 318 based on the selected governing building code.

The screen capture below shows the full screen for concrete column design. See items below for descriptions of items that are specific to the concrete column design module.

The two buttons and immediately set the value for elastic modulus "E" to the values as described on the button.

Concrete Shape

This tab is specific to the concrete column selection. It allows you to select from 12 different column shapes. Simply click the button surrounding the column shape icon and the screen below will change to allow specific data input for measurements and reinforcing layout.

Following the screen capture below we will show ALL the data input areas for ALL the column shapes with descriptions as needed.

Note that this module does a very detailed biaxial analysis of the column cross section using exact numerical methods.
