The role of higher-“mode” pushover analyses in seismic analysis of buildings is examined in this paper. It is demonstrated that the higher-“mode” pushover curves reveal plastic hinge mechanisms that are not detected by the first-“mode” or other FEMA-356 force distributions, but these purely local mechanisms are not likely to develop during realistic ground motions in an otherwise regular buildi...

HURRICANE KATRINA WAS THE MOST DEVASTATING natural disaster in US history. Large parts of New Orleans and nearby Louisiana parishes were destroyed. About 90 000 square miles of the Gulf Coast, an area roughly the size of Great Britain, was declared a federal disaster area. The often contaminated flood waters covering much of New Orleans for almost 2 months contained a mix of raw sewage, bacteri...

Staphylococcus capitis EPK1 produces a glycylglycine endopeptidase, ALE-1 (M. Sugai, T. Fujiwara, T. Akiyama, M. Ohara, H. Komatsuzawa, S. Inoue, and H. Suginaka, J. Bacteriol. 179:1193-1202, 1997), which hydrolyzes interpeptide pentaglycine chains of cell wall peptidoglycan of S. aureus. Characterizations of the enzyme activity and cloning of ale-1 revealed that ALE-1 is very similar to prolys...

INTRODUCTION Hurricane Katrina, a Category 3 hurricane, made landfall in August 2005. Approximately 1,500 deaths have been directly attributed to the hurricane, primarily in Louisiana and Mississippi. In New Orleans, Louisiana, most of the healthcare infrastructure was destroyed by flooding, and > 200,000 residents became homeless. Many of these internally displaced persons received transitiona...

The addition of a rocking structural system will soften the connection between foundation and superstructure help beam-column connections to become softer than typical ones. These structures, with systems, follow elastic gap opening mechanism seismic response. Post-tensioned prestressed tendons dampers are used in systems enable structure return its initial position (self-centering) dissipate e...

This paper presents a new approach to the project of steel buildings, mainly focused on architectural, structural, and seismic design stairs. The objective is structural stair system capable controlling damage contributing bracing building. article begins with review standard (ATC, FEMA, EC8) which current criteria for buildings stairs are based. research based two spatial building models (A–B)...

The 1993 flooding of the Midwestern United States was of long duration, spatially extensive, and economically damaging. Estimated property losses exceeded $12 billion, and millions more were suffered in indirect losses (IFMRC 1994; Myers and White 1993). Fifty people were killed. At least 26,000 people were evacuated from their homes, and approximately 100,000 buildings were affected. The flood...
