Night School 13: Design of Industrial Buildings
Written and Presented by James M. Fisher and Jules Van de Pas
Winter 2017 Course
This Night School consists of eight 90 minute lessons. Each lesson consists of approximately 75 minutes of discussion followed by a question and answer period. The lessons are split between the design of buildings without overhead cranes and those structures with light duty and heavy duty overhead cranes. Critical design issues and design approach techniques are discussed. Calculations are presented in a manner that serve as a teaching tool for engineers. A complete design example (anchor rods to roofing) of a 50-ton overhead crane building is illustrated.

In Lesson 1, loads as required by IBC 2015 and ASCE 7-10 are discussed as well as owner established design criteria. Advantages and disadvantages of various roof and wall systems are presented. Serviceability issues and other design considerations are discussed in detail for roof and wall types. Expansion joint requirements and details for expansion joints for both buildings without overhead cranes and those with overhead cranes are presented. Member selection guidelines for optimum design are discussed.
Lesson 2 focuses on roof and bay optimization. Design considerations for roof trusses are discussed. Connection considerations, permanent, and erection bracing for roof trusses are presented. Economic issues pertaining to: span-to-depth ratios, location of splice points, use of tee chords, the advantages of LRFD, use of high strength steels, web arrangements, and the value of repetition of member sizes are all discussed. Design considerations for: Block Shear and Shear Rupture, Orientation of Wide Flange Chords, Slip Critical Joints, Seat Connections, and Splices are discussed. Additional information not covered in Lesson 1 on optimum member selection, and details for the support of hanging loads and roof top units are provided. An interactive Spreadsheet tool is demonstrated for selecting optimum bay layout. Roof diaphragm details and design requirements are also discussed.
Lesson 3 deals with lateral load resisting systems which includes, roof horizontal bracing systems, braced frames, and rigid frames. Economical choices for the lateral load system are discussed. Moment connections details for connecting Joist Girders to columns are provided along with practical suggestions for the maximum moment resistance for each detail. Three examples are given, these include a braced frame using LRFD and ASD, and a rigid frame using ASD. The braced frame examples include the design of the roof diaphragm. The rigid frame example includes a “hand calculation” of a moment connection as well as a demonstration of a Spreadsheet solution.
Lesson 4 sets the stage for a complete building design for a two bay 50-ton overhead crane building. The project description and design criteria including all loads and serviceability requirements are discussed. Preliminary design procedures and calculations are provided for the runway girders, columns, and roof members beginning with the determination of required eave height based upon the owner’s requirement for the crane hook height. A discussion on the various choices for column types and the preliminary design hints for each is provided. A weight comparison between 30 ft. and 40 bay spacing is also provided.
Lesson 5 includes the design of a typical 30-foot-long crane runway girder and an analysis for a typical frame in the example building. A crane girder design procedure is demonstrated, including the evaluation of strength and serviceability limit states. Examples of proper details for minimizing fatigue effects for crane runway girders are presented. Development of the frame loads, including seismic loads, and the selection of the seismic force resisting system are discussed. Second order analysis methods and calculations for estimating second order effects are presented.
Lesson 6 incorporates the results of the frame analysis discussed in lesson 5 to demonstrate the design of the building columns, crane columns, and moment connections. The AISC Manual beam column tables are used for the design of the beam columns to illustrate their use. The design of the Ordinary Moment Frame connection of a Joist Girder to the building column is provided. The development of the specification for the Joist Girders, for the example building, using the Steel Joist Institute’s Technical Digest 11 is also discussed. The design of the column anchor rods is provided including evaluation of limit states according to ACI 318 Chapter 17. Discussion of the recommendations of AISC Design Guide 1 are included in the example, as well as, the calculation for the thickness of the column base plate.
Lesson 7 begins with the design of a 60-foot-long crane runway girder, the backup girder, and the horizontal lacing which connects the backup beam to the runway girder. The design of the longitudinal bracing system is then presented including the roof longitudinal bracing, and the building longitudinal bracing. The loads and forces acting on the bracing members and struts are developed, the members selected, and typical details are discussed. The crane bumper force calculation is provided and the crane longitudinal bracing design is shown. The design of the end wall bracing is also provided. Connection details for the braces are provided.
Lesson 8 is the final lesson and the final design of the 50-ton overhead crane building design example is presented. The final roof and wall design is presented with a discussion relative to the design of standing seam roofs and to membrane roofs. Advantages and disadvantages of standing seam roofs are presented. Design concerns for metal roof deck and open web joists relative to mechanical membrane roofs subjected to wind uplift forces are presented. Proper specifications for open web joists subjected to gravity, uplift and roof ponding are discussed. Design procedures for cold-formed girts are presented along with wind column design. Lateral bracing calculations for the Ordinary Moment Frame (OMF) columns and beams are performed and discussed. The lesson concludes with suggested general notes for the installation of the runway beams.
