The support and foundation shall be designed for this obtained value. The stress due to seismic load on the pipe can be calculated using bending equation σ = M/Z. (σb)midspan =PL/4Z =232 * 20/4 * 16.7 = 70 PSI.

Data Availability is the Key for Plant Protection

Designing a piping system for seismic event is largely dependent upon data availability and its proper interpretation. Even though static analysis is the most popular and proven method in pipe stress analysis, the response spectrum analysis provides additional and useful information like modes of vibrations and frequencies.
