TEACHING COLD-FORMED STEEL DESIGN TO TECHNOLOGISTS by Richard K. Keplarl and Edward R. Estes, Jr.2 The four-year Civil Engineering Technology curriculum is designed to produce a graduate who is able to significantly contribute to an engineering team with a minimum of orientation, whether their activities be in engineering design or in industrial or construction proj ect control. The "hands-on" experience obtained in laboratories which stress the importance of in-depth report preparation, combined with the practical approach to analysis and design in lecture and recitation classes, provide the graudate with many of the attributes needed by today's changing companies. An important feature of these curricula is their ability to attract the more practical, productivity-oriented individuals to the program. The tendency of engineering curricula to gravitate toward higher mathematics and highly theoretical courses has created a gap between the newly-graduated engineer and the two-year engineering technician which has been bridged by the enigneering technologist. Engineering technology faculty, recruited for their practical experience and teaching ability, usually do not have the Ph.D. required of research-oriented faculty. Thus, the engineering technology student receives an insight into his future career normally not available from the Ph.D. instructor who may have limited practical knowledge. In recognizing the need in the real world for the baccalaureate graduate in Civil Engineering Technology to function in a broad spectrum of engineering activities, the curriculum at Old Dominion Univeristy, as presently approved by the Accreditation Board for Engineering and Technology (formerly Engineer's Council for Professional Development), requires each student to acquire an understanding of practical problems in the areas of structures, water resources, environmental technology, surveying and inspection of construction and related materials. In addition, the undergraduate is permitted at least eight hours of electives to enable him to take technical courses supporting his specific area of interest. Realizing the increasing use of cold-formed steel in construction and in industry, yet operating under the constraints of the established curriculum, a plan has been devised to include cold-formed steel design into the program without introducing a specific course or option as such. The first exposure for the ODU student to cold-formed steel is in the junior year in the course entitled "Civil Engineering Technology Laboratory." Originally intended to function presumably as a buffer course for the large percentage of transfer students entering from two-year, associate degree programs, the course also serves to give an insight to all students into lAssociate Professor, Civil Engineering Technology, Old Dominion University 2 -Professor, Civil Engineering Technology, Old Dominion University, Norfolk, Virginia 33 34 SIXTH SPECIALTY CONFERENCE their career opportunities in Civil Engineering Technology. The treatment of statics and strength of materials problems utilizing the computing facilities of both the department and the university serves to coalesce the diverse mechanics backgrounds of the students, so that each is better prepared to handle the upcoming courses in structural analysis and foundations. A study unit devoted to cold-formed steel design, as well as various other units, is added to provide an exploratory experience related to typical project assignments. The coverage, including the concepts of thin material as opposed to thicker steel elements, introduces the student to the AISI Design Manual, Specification and Commentary. Several problems similar to the illustrative problems in the Manual are assigned to the students. These include the concept of effective width, and calculation of section properties. During this same semester the student is taking a course in construction materials systems. Here he studies not only the basic roll-forming process, but also specific applications for the cold-formed steel products. The roll-forming process and the apparently limitless proliferation of available shapes through this process along with their advantages and disadvantages are introduced in the construction materials system class. Systems com-prised of various combinations of steel roof deck and floor deck, open web joists, C-section joists, and studs provide a broad spectrum of applications for cold-formed products. An emphasis is placed on the wealth of technical information and assistance that can be received from associations such as AISI and from responsible manufacturers. To complete this initial exposure to practical, career-related activities, the student must take a laboratory in the testing and in-spection of construction materials. Here the student actually conducts tests involving steel components, including the effects of cold forming on the mechanical properties, and must prepare comprehensive reports covering the experimental findings. Although the structural analysis course in the spring of the junior year is a typical analysis course covering elastic materials in general, there are areas which tie into cold-formed steel design. In studying truss analysis, an open-web steel joist is treated. Since available computer programs relieve the structural designer of many laborious calculations and represent the present state-of-the-art, the structural analysis course in-troduces the student to the many computer programs available. Thus, it is appropriate to include exposure to the hyperbolic-paraboloid roof system analysis available in the AISI computer program library, DEBU and STAN. The steel design course in the first half of the senior year, traditionally devoted to hot-rolled steel, has been modified to include aold-formed steel design as well. Not only are open-web joists and roof deck included, but cold-formed C-sections for joists and studs as well. The AISI computer program STUD is utilized in wall design. Cold-formed box sections are also treated along with space frame applications of light-gage tubular sections. TEACHING COLD-FORMED STEEL DESIGN 35 Connections are of extreme importance in any structure. The coverage of connections has been expanded to consider the various methods available to connect gage material including both welding and high-strength bolting. The benefits of diaphragm action in the design of steel structures and the design of the details necessary to insure diaphragm action are also included in the senior course in drafting systems. This particular course not only familiarizes the student with reinforcing steel details and structural steel details but includes contract drawings for open web joists, steel decking, and cold-formed structural shapes. The course also introduces the student to computer drafting and detailing. Utilization of a product in construction requires that it be specified either on the design drawings o'r in the specifications. The final course incorporating cold-formed steel deals with contract documents. Included in this course is an exercise in specification writing. Thus, the proper documents are prepared to assure the usage of cold-formed steel in a con-struction project. These elements of construction management are most im-portant to the civil engineering technologist, i.e., contracts, bonds, insurance, specification writing, the assembly of bid documents, bidding procedures and arbitrations. Figure I shows the four-year curriculum in Civil Engineering Technology with the courses highlighted which involve exposure to cold-formed steel. Figures 2 through 8 give the course descriptions and brief outlines of their contents, again with the cold-formed steel areas highlighted. Typical problems from these courses are found in the Appendix. Thus, without compromising the Civil Engineering Technology curriculum by creating numerous options, cold-formed steel design has been accommodated. The graduating technologist is properly prepared to use cold-formed products in a practical and economical way. 36 SIXTH SPEC1ALTY CONFERENCE CIVIL ENGINEERING 7::CliNOLOGY (An ABET Aooredited Curriculum) ENGL 110 MATH 102 MET 100 MET 102 HET 110 MET 112 ----CET 200 CET 210 CET 215 MATH 205 PHYS 111 ----CET 300 CET 310 CET 345 -fI,I.TH 304 MET 300 SPCH 395 OR lst Semester English Composition Algebra & Trig I Engineering Graphics Engineering Graphics Lab Technical Processes Technical Processes Lab Social Studies 3rd Se:nester Statics Elementary Surveying Elementary Surveying Lab Calculus I General Physics Humanistic Studies 5th Semester Civil Engineering Technology Lab Construction Systems Testing & Inspection of Construction Materials Math for Technolo~ists Thermodynamics Tecbnical Communication Workshop (1) + Free Elective (2) SPCH 101 Pl'blic Speaking Humanistic Studies 7th Semester -------GET !,10 Concrele OR WatEr kC30urce Techi..o10gy Structural Steel Design Drafling Systmns Engineering Economy MET 400 Indus~rial Operations Fre:e Elective 3 3 2 1 2 1 3 15 3 3 1 3 4 3 17 1 3 1 3 3 J 3 17 3 3 3 1 -. 3 15 MATH 103 CS 155 MET 120 MET 125 ---------CET 220 CET 240 CET 245 ENGL 235 MATH 206 PHYS CET HET MET MET ll2 ~40 CET 430 GET 435 'EET 350 EET 355 Figure 1 2nd Semester Algebra & Trig II Fortran PrograIIuning Technical Drauing Technical Dra"ring Lab Laboratory Science Social Studies 4th Semester Strength of Materials Advanced Surveying Advanced Surveying Lab Technical Writing Calculus II General Physics 6th Semester Soils Testing & Inspection Fluid Hech<:nics Fluids Laboratory DYU2'!llics Humanistic Studies 8th Semester Contract DocumCTLLS Environ",en tal Tecr_nology Environmental Lab Fund of Electric31 T,:,chnvlogy Electrical Lab Technical Elective 3 3 2 2 4 3 17 3 3 1 3 3 4 17 3J 3 1 3 1 3 3 17 3] 3 1 3 1 3 i"4 TEACHING COLD-FORMED STEEL DESIGN 37 CET 300 CIVIL ENGINEERING TECHNOLOGY LAB Catalogue Description Laboratory 3 hours; one credit.
