16、tion,or it may be voluntarily instituted for loss prevention and worker and public safety.While seismic loads are mentioned in the various sections of the ASME B31 Pressure PipingCode,and allowable stresses are provided for occasional loads,there has been a need to providemore explicit and structured guidance for seismic design of new piping systems,as well as retrofitof existing systems.In order to respond to this need,this Standard was prepared by the ASME B31Mechanical Design Technical Commit
