Foundation3D completes the foundation design of a single or a stacked exchanger (maximum three exchangers) with the following data input.
In the case of exchangers and horizontal vessels, the equipment geometry page allows you to input Material Weights and Geometry, Common Geometry, and Common Loads. You may also add or remove equipment (i.e. stacked exchangers) in the workspace editing toolbar above. The new equipment will retain the common geometry and common loads specified but you will need to reenter the material weights and geometries specific to the new equipment. By convention, each added exchanger stacks on top of the previous exchanger.
If you are designing a foundation for a single or a stacked exchanger, you must enter the data for the bottom most exchanger always noted as “Exchanger”.
The effective diameter and effective length fields refer to the effective dimensions that Foundation3D will use in future for calculating the wind forces on the exchanger based on the ASCE code. Currently this feature is not implemented.
The percent weight to fixed pier refers to the percentage of axial loads (operating, shipping or erection, test weights) that Foundation3D will use to distribute to the fixed pier. Usually it is 50% on the fixed pier and the sliding pier. However if you need to use a different value, you can enter it in this field and Foundation3D will use this value in calculating the loads on the fixed pier and the sliding pier. In other words, using a value different than 50% will distribute the equipment weight to the two supports unequally.
If you want to apply the entire bundle pull force to the fixed pier regardless of the friction value, you can check the option “Apply Full Bundle Pull Shear to Fixed Pier”.

Strapped Footings
A horizontal exchanger with two footings - one under each exchanger support can be strapped with a strap beam or tie beam to create a Strap Foundation. For more details on designing such a strap foundation refer to the topic Strap Footing. The two footings can be strapped together on the Footing Layout page. For more details on the operations on footing layout page, refer to Footing Layout.
