(OP)
I'm currently working on an abutment design for a single span bridge on rural road in western Massachusetts. I am planning on looking at all applicable load combinations for two loading cases. For the first case I would consider a 10 year flood condition and for the second case I would consider an ordinary water level condition. I am curious about the general consensus on whether earth quake loads should be included in the 10 year flood loading condition. It seems to me that because a 10 year flood and an earthquake are major events the probability of them happening simultaneously is extremely low. Is this an incorrect assumption?






RE: Loading Conditions
however the real reason that I'm posting is to question the 10 flood requirement. All bridges that I have been associated with were designed for at least a 50 year or perhaps a 100 year flood (or more). Those 10 year "events" have the habit of happening all too often.
