ABSTRACT:
A children’s hospital in Iowa serves critical care children throughout the state. Considering the benefits of light and views on patient recovery, the Architect designed oversized glass in the exterior patient rooms. The Owner required that the hospital including the patient rooms remain operational even in the case of a direct EF-3 tornado strike. This presented a significant design endeavor – to specify the necessary strength and to prove cladding performance for such an extreme event; however rare the likelihood of occurrence. Engineering analysis of the glass and metal framing was supported by full-size mock-ups to confirm that the cladding performance met the Owner’s requirement.
LEARNING OBJECTIVES:
1. How tornados are categorized and how they exceed code requirements.
2. Resources for tornado design.
3. Wind tunnel analysis and determination of equivalent loads for tornados
4. Difference between design load, ultimate load and impact capacity
5. Glazing design with laminated glass for impact resistance
6. Large missile impact testing for tornados and how these tests exceed hurricane impact tests.
PRESENTER BIO:
Bruce Kaskel is an Architect and Structural Engineer with Wiss, Janney, Elstner Associates, Inc. He has over 35 years’ experience with cladding and glazing - both investigative and repair designs.
