The only load that need be considered for a pipe submerged within a basin i the inertial seismic load on teh pipe (and its contents) alone. Convective and impulsive loads, important to design of tank shells are not applicable to pipes within the basin. This is becasue the pipe is surrounded by...
I am looking for some clarification regarding the seismic load calculation for a pipe support anchorage design. The scenario is a pipe submerged in a water-filled concrete basin which is located in a high seismic region and experiences sloshing. In such a scenario, I understand that the pipe and...
Christian - just wait until the world turns to performance based design! It will get really fun then! -- Bill Allen P.E., S.E., M.ASCE Principal Allen Designs Mission Viejo CA --
Ah, I see. I tend to think of the ASCE 7 as a balancing act between ease of implementation and economy of design, but you make a great point about the importance of transparency. I would argue that the current live loads are very easy for engineers to use (aside from those pesky load...
While I understand the pros and cons of ASD & LRFD, once AISC combined them into one manual, the differences began to disappear to all that remains is a conversion between the two. What is the load and what is the capacity? Well, that depends... the public (or client) demands a clear answer...
Ron, I appreciate the thorough explanation, and I'm sorry for not responding sooner. In fact, I wish this timeline was part of my undergrad curriculum. Only after entering practice did I realize how little I knew about ASD, and how much my understanding of design loads and limit states...
James, Thanks for the response. You make a good point, but for environmental hazards, the safety factor lives in the return period to establish uniform risk. For example, I'm told that snow loads in ASCE 7-16 and earlier resulted in dramatically different probabilities of failure across...
