Technical Papers

The developer of the CFS software authored the following technical papers in support of calculations utilized in the software. These investigations have also led to consideration by AISI for inclusion the North American Specification.

Engineering Practice

The CFS application is not intended to guide you regarding best engineering practices. Nor is the author in a position to make recommendations on engineering practice. Such issues should be pursued with engineers experienced in the type of construction, educational institutions involved in related research, or the appropriate building officials.

Specification Questions

Any specification is subject to interpretation when attempting to apply it to real world situations. CFS makes some assumptions in the calculations that it performs. These are explained in the various portions of the documentation as related to each type of calculation. Further interpretation of the AISI Specification and the ASCE Specification, or any similar specification, is beyond both the scope of this application and the responsibility of the author. Such issues should be pursued with AISI or ASCE as appropriate.

Several AISI standards and other technical documents are available to download from CFSEI.

Verification of Computations

CFS has been used extensively for many years. Computational bugs have been extremely rare in recent years, however it is still possible that one could arise. If you disagree with an output, you should first review all the inputs and their meanings, and understand all the assumptions as stated in the documentation. You can also use the trace feature to check the details of the calculations. If you still disagree with an output, please report it to us.

Suggestions

The CFS application has evolved through many phases of improvement and refinement. To continue in this direction, comments are encouraged. Whether you have a suggestion for a minor change, need a new feature, or simply don't like the way something works, please send us your comments.
