The Morning Exercises at Harvard’s 363nd Commencement at Tercentenary Theatre on May 29, 2014.
For more information on this year’s Commencement, visit http://news.harvard.edu/gazette/.
Welcome to the 363rd Harvard Commencement. Although Harvard’s first Commencement in 1642 is more than 372 years behind us, Commencement numbering has fallen out of step as exercises were omitted for reasons ranging from war to plague. The cumulative effect is that 2014, for example, marks only the 363rd Harvard Commencement.
Commencement at Harvard is comprised of three components: the ceremonial Morning Exercises, during which University degrees are conferred; the mid-day luncheons and diploma-awarding ceremonies at the undergraduate Houses, Graduate and Professional Schools; and the afternoon Annual Meeting of the Harvard Alumni Association, during which Harvard’s president and the featured Commencement speaker deliver their addresses.
The Morning Exercises, which convene in the outdoor Tercentenary Theatre, are attended by approximately 32,000 degree candidates, family members, faculty, alumni/ae, and guests.

This seminar is designed for training engineers and is committed to finishing a multi-story special metal instant resisting frame illustration so that prevalent concerns and software of requirements can be illustrated. As the illustration is getting introduced, tough-to-understand ASCE 7-ten and AISC Seismic Provisions (AISC 341-ten) are described, including why they are demanded in the 1st area. The illustration:
- Commences with columns and beam sizes picked to fulfill the energy and drift requirements of ASCE 7-ten.
- Applies AISC 341-ten and AISC 358-ten beam and column limits.
- Opinions and applies the connection requirements for one) welded unreinforced flange – welded website (WUF-W), and two) bolted flange plate (BFP) connections assembly the AISC prequalified connection requirements in AISC 358-ten.
- Decides the demanded energy for the columns, column splice, and the column base.
- Locates the protected zones and desire significant welds in the instant frame method.
