Course Outline

This six hour course includes the following information:

1. Antiquated Structural Systems:

The course content was first published in STRUCTURE® magazine as five separate articles between 2007 and 2008;

This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.

Learning Objective

At the conclusion of this course, the student will:

Intended Audience

This course is intended for structural engineers and architects.

Benefit to Attendees

The attendee of this course will be able to have a better understanding of the many different types of older structural systems that are still encountered in urban areas.

Course Introduction

Engineers involved with renovation and rehabilitation projects need to be aware of the specifics of antiquated structural systems in order to develop non-destructive and unobtrusive solutions. Information concerning antiquated structural systems provided by this course has been compiled and made available because the history of older structural systems is far less documented than the history of architecture. Part 2 of this course will provide the user with an understanding of a number of different types of antiquated structural systems that one can typically encounter in urban areas of the U.S.

Course Summary

The designs of all of the antiquated structural systems presented in this course were originally based on the basic engineering theories and construction experience of their respective era.  Load tables were also commonly developed and published by most of the manufacturers.  The problem with all of these systems, when one encounters them in an existing building, is that in the absence of existing drawings it is difficult to determine the internal reinforcement and, subsequently, the load carrying capacity of the system.  However, it is hoped that this course, by identifying the many different types of products that were in use at one time or another, will assist the users in their research of an antiquated or archaic system when it is encountered in an existing structure.

Author’s Commentary on the Cited References

For all of the articles that have been either published to date or will be in the future for the Antiquated Structural Systems Series, I have obtained the information presented by researching material that was already published by individuals or previously disseminated by manufacturers or industry organizations. In all cases, I have contacted the source of the information (when they were either alive or available) and requested permission to reprint figures, charts, or other similar images. This approach has enabled me to fulfill the primary purpose of the series, which is to compile and disseminate a resource of information to enable the sharing of knowledge concerning existing structural systems within the structural engineering community.
