First, you have to realize that NYC is not a very seismically active region (UBC Zone 2A, BOCA accelerations Aa and Av 0.10). San Francisco is in UBC Zone 4 (Z=0.40, plus near-source factors would increase the design forces). Second, if I were there during an earthquake, I'd be a lot more worried about being hit by a falling parapet from one of the URM buildings constructed prior to 1950, say. > ---------- > From: Michelle Trzecinski[SMTP:trez(--nospam--at)execpc.com] > Sent: Wednesday, September 09, 1998 7:00 PM > To: seaint(--nospam--at)seaint.org > Cc: trez(--nospam--at)execpc.com > Subject: What happen when earthquake shaking bridges in New York > City? > > Hi, I wonder if that really can happen to many people on moderate > earthquake if they stike at New York City on their bridges and many > people will be died because they don't have similiar to S.F.
