Based on a sewage treatment plant (STP) in the Philippines, this article introduces the structural seismic design mainly under the control of U.S. codes. The comparison highlights the difference between U.S. codes and Chinese codes in terms of seismic load, which including dynamic water pressure, response spectrum, the two stage analysis method, etc. Through comparison, it can be seen that the U.S. codes are more detailed in seismic load definition than Chinese codes. The article also points out the critical points and difficulties in the seismic design of STP projects or water-retaining structure based on U.S. codes, providing valuable reference for similar STP oversea projects in the future.

摘要

Based on a sewage treatment plant (STP) in the Philippines, this article introduces the structural seismic design mainly under the control of U.S. codes. The comparison highlights the difference between U.S. codes and Chinese codes in terms of seismic load, which including dynamic water pressure, response spectrum, the two stage analysis method, etc. Through comparison, it can be seen that the U.S. codes are more detailed in seismic load definition than Chinese codes. The article also points out the critical points and difficulties in the seismic design of STP projects or water-retaining structure based on U.S. codes, providing valuable reference for similar STP oversea projects in the future.
