Ask FEMA how and where they compiled their data for these astounding news

	Subject:	FEMA report on steel buildings

	Yesterday CNN reviewed a FEMA report that steel frame buildings,
	especially those built prior to 1994, contained a design
	flaw that concentrated temblor stresses at weld points between
	beams. New designs move stresses into the beams themselves
	for increased strength. Apparently this failure mode was
	observed in Kobe.

	Can anyone point to more in-depth information about this?
	If design changes were introduced in 1994, why is this news
	now? Have there been analyses of high-rise, steel frame
	buildings in LA or San Francisco that indicate they are
	more likely to be damaged than was previously thought?
	What design changes were introduced?
