DESCRIPTION: From the previously completed labs, students are to use the appropriate floor loads and tributary areas to calculate the load the given girder and beam will be subjected to. After loads are calculated, sections must be checked for strength, several sections are chosen to meet the design criteria, and in the end, the most economical (lightest) section may be selected. Then the section must be checked for stiffness. |

DESCRIPTION: From the previously completed labs, students are to use the appropriate floor loads and tributary areas to calculate the load the floor beam will be subjected to. Checking for strength and unbraced length effects, several sections are chosen which meet the design criteria, and in the end, the most economical (lightest) section is chosen. |

DESCRIPTION: Use these instructions to make your own models to demonstrate beam buckling modes. All you need is some overhead transparency film and some packing tape! Dimensions are provided for models which will exhibit lateral torsional buckling, local flange buckling, and local web buckling. |

DESCRIPTION: This low-budget in-class demonstration lets students directly see composite action as well as the effect of placement of shear connectors on composite action. The directions are set up assuming the instructor or TA is making the models ahead of time and the instructor leading the demonstration. One can rewrite the instructions as an “experiment” to be conducted in-class by teams. |

SPREADSHEETS: Beam Design Spreadsheets |

DESCRIPTION: The Microsoft Excel Spreadsheet application AISC2005-BeamDesignAid.xls calculates the LRFD and ASD flexural and shear design strengths of W- and M-shaped sections for a given unbraced length Lb, bending coefficient Cb, and material yield strength, Fy. Once these input values are specified, the flexural design strengths are automatically computed for all listed sections based on local and overall lateral-torsional buckling criteria. The user can then sort the sections based on size, strength, or stiffness. Sections that are presented in bold type are the most economical for the strength level they have. |

DESCRIPTION: Use this spreadsheet to illustrate computation of moment capacity for W sections as limited by yielding and lateral torsional buckling. Enter different W-shapes, moment demands, unbraced lengths, and Cb and Fy values; moment capacity curves are plotted. Courtesy of John Zachar, MSOE AE Dept. |
