Commentary: When the Owner’s Designated Representative for Design shows the complete design of the Connections in the structural Design Drawings, the following information is included: (a) All weld sizes and lengths; (b) All bolt sizes, locations, quantities and grades; Code of Standard Practice for Steel Buildings and Bridges , March 7, 2000 AMERICAN INSTITUTE OF STEEL CONSTRUCTION 13

APPENDIX PAGE 52 (c) All plate and angle sizes, thicknesses and dimensions; and, (d) All work point locations and related information. The intent of this approach is that complete information necessary for Connection detailing, fabrication and erection is shown in the structural Design Drawings. The Steel Detailer will then be able to transfer this information to the Shop and Erection Drawings, apply- ing it to the individual pieces being detailed. When the Owner’s Designated Representative for Design allows the Fabricator to select or complete the Connections, this is commonly done by referring to tables in the Contract Documents or in the AISC Manual of Steel Construction, or by schematically showing the types of Connections required in the structural Design Drawings. The Steel Detailer will then configure the Connections based upon the design loads and other information given in the structural Design Drawings. If the desired Connection is not cov- ered in those tables, a detail of the “special” Connection should be contained in the structural Design Drawings. This detail should provide such information as weld sizes, plate thicknesses and quan- tities of bolts. However, there may be some geometry and dimen- sional information that the Steel Detailer must develop. The intent of this method is that the Steel Detailer will select the Connection materials and configuration from the referenced tables or complete the specific Connection configuration (i.e. dimensions, edge dis- tances and bolt spacing) based upon the Connection details that are shown in the structural Design Drawings. This method will require the skill of an experienced Steel Detailer, who is familiar with the AISC requirements for Connection configurations, capable and experienced in the use of the Connection tables in the AISC Manual of Steel Construction and capable of calculating dimensions and adapting a typical Connection detail to similar situations. Notations of loadings in the structural Design Drawings are only to facilitate selection of the Connections from the referenced tables. It is not the intent of this method that the Steel Detailer practice engineering. If there are any restrictions as to the types of Connections to be used, particularly as it relates to simple shear Connections, it is required that these limitations be set forth in the structural Design Code of Standard Practice for Steel Buildings and Bridges , March 7, 2000 AMERICAN INSTITUTE OF STEEL CONSTRUCTION 14

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
