Evolution of Assessment of Wind Speeds in Tornadoes

Friday, February 22, 2019 – 4:30 pm

Location: Whitaker Lab 303, Lehigh University, 5 East Packer Avenue, Bethlehem, PA

Overview:

Tornadoes are windstorms that are unpredictable and short lived. As a result it is difficult to put wind measuring instruments in the path of a tornado. Wind speeds in tornadoes are assessed with indirect methods of physical evidence of damage or with remote sensing. This presentation discusses evolution of assessment of wind speed in tornadoes since 1970.  In particular, it traces engineering based estimated (calculated where possible) wind speeds from damage, the development of F-scale by Dr. Ted Fujita in 1970 and its enhancement into EF-scale in this millennium. The presentation also describes current efforts to improve EF-scale and current/future efforts in remote sensing procedures using radars.

Some Long-Span and Some Tall Buildings by SawTeen See

Friday, March 29, 2019– 4:30 pm

Location: Whitaker Lab 303, Lehigh University, 5 East Packer Avenue, Bethlehem, PA

Overview:

SawTeen See, a structural engineer with 40 years’ experience, will share some of the highlights of her collaborations with architects in the design of pedestrian bridges, museums, convention centers, and some of the world’s tallest buildings.  She will discuss projects such as the AIG pedestrian bridge in Hong Kong, the NASCAR Hall of Fame in Charlotte, NC, the Baltimore Convention Center Expansion, the 492m Shanghai World Financial Center, the 555m Lotte World Tower in Seoul (the 5th tallest in the world), the 644m PNB 118 tower under construction in Kuala Lumpur, Malaysia, and innovations for some super high-rises of the future.

The Role of Quality Control in Some Notable Bridge Problems

Friday, April 12, 2019– 4:30 pm

Location: Whitaker Lab 303, Lehigh University, 5 East Packer Avenue, Bethlehem, PA

Overview:

The role of quality control in the problems that occurred in 3 major bridges will be presented. Often quality control of bridge structures is solely concerned with the quality of the contractors building the bridge. Quality control in the design office is also critical and should not be overlooked. In addition, the designer needs to heed the warnings in the specifications when specifying products. A note on the plans while clearly written is also no guarantee of quality if they are not enforced during fabrication. A tale of 3 bridges illustrating the importance of the control quality from design, material selection, and through to fabrication will be presented.
