While seismic loads are mentioned in the various sections of the ASME B31 Pressure Piping Code, and allowable stresses are provided for occasional loads, there has been a need to provide more explicit and structured guidance for seismic design of new piping systems, as well as retrofit of existing systems. In order to respond to this need, this Standard was prepared by the ASME B31 Mechanical Design Technical Committee. This 2008 edition was approved by the American National Standards Institute on April 21, 2008 and designated as ASME B31E-2008. iv Copyright ASME International Provided by IHS under license with ASME LicenseeFMC Technologies /5914950002 Not for Resale, 05/13/2009 010951 MDTNo reproduction or networking permitted without license from IHS --,,,,,,,,,,,,,,,--,,,,,,,--- ASME B31 COMMITTEE Code for Pressure Piping The following is the roster of the Committee at the time of approval of this Standard.

Rules for each Standard provide standardized guidance for a specific task found in one or more B31 Section publications, as follows a B31E, Standard for the Seismic Design and Retrofit of Above-Ground Piping Systems, establishes a for the seismic design of above-ground piping systems in the scope of the ASME B31 Code for Pressure Piping. b B31G, Manual for Determining the Remaining Strength of Corroded Pipelines, provides a simplified procedure to determine the effect of wall loss due to corrosion or corrosion-like defects on pressure integrity in pipeline systems. c B31J, Standard Test for Determining Stress Intensification Factors i-Factors for Metallic Piping Components, provides a standardized to develop the stress intensification factors used in B31 piping analysis. This is B31E, Standard for the Seismic Design and Retrofit of Above-Ground Piping Systems. Hereafter, in this Introduction and in the text of this B31 Standard, where the word “Standard” is used without specific identification, it means this B31 Standard. It is expected that this Standard will be incorporated by reference into the appropriate sections of B31. vii Copyright ASME International Provided by IHS under license with ASME LicenseeFMC Technologies /5914950002 Not for Resale, 05/13/2009 010951 MDTNo reproduction or networking permitted without license from IHS --,,,,,,,,,,,,,,,--,,,,,,,--- w w w . b z f x w . c o m INTENTIONALLY LEFT BLANK viii Copyright ASME International Provided by IHS under license with ASME LicenseeFMC Technologies /5914950002 Not for Resale, 05/13/2009 010951 MDTNo reproduction or networking permitted without license from IHS --,,,,,,,,,,,,,,,--,,,,,,,--- w w w . b z f x w . c o m ASME B31E-2008 STANDARD FOR THE SEISMIC DESIGN AND RETROFIT OF ABOVE-GROUND PIPING SYSTEMS 1PURPOSE This Standard establishes a for the seismic design of above-ground piping systems in the scope of the ASME B31 Code for Pressure Piping. 1.1 Scope This Standard applies to above-ground, metallic pip- ing systems in the scope of the ASME B31 Code for Pressure Piping B31.1, B31.3, B31.4, B31.5, B31.8, B31.9, B31.11. The requirements described in this Standard are valid when the piping system complies with the materials, design, fabrication, examination, testing, and inspection requirements of the applicable ASME B31 Code section. 1.2 Terms and Definitions active components components that must per an active function, involving moving parts or controls dur- ingorfollowingtheearthquakee.g.,valves,valveactua- tors, pumps, compressors, and fans that must operate during or following the design earthquake. axial seismic restraint seismic restraint that acts along the pipe axis. critical piping piping system that must remain leak tight or operable see definitions during or following the earthquake. design earthquake the level of earthquake for which the piping system is to be designed for to per a seismic function position retention, leak tightness, or operability. ductile piping system in the context of this Standard for seismic qualification, ductile piping system refers to a pipingsystemwherethepiping,fitting,andcomponents are made of material with a minimum elongation at rupture of 15 at the temperature concurrent with the seismic load. free-field seismic the ground seismic at the facility location. in-structure seismic the seismic excitation within a building or structure, at the elevation of the piping sys- tem attachments to the building or structure. lateral seismic restraints seismic restraints that act in a direction perpendicular to the pipe axis. 1 leak tightness the ability of a piping system to prevent leakage to the environment during or following the earthquake. noncritical piping piping system other than critical pip- ing that nevertheless must meet the requirements for position retention. operability the ability of a piping system to deliver, con- trol throttle, or shut off flow during or after the design earthquake. position retention the ability of a piping system not to fall or collapse in case of design earthquake. seismic design the activities necessary to demonstrate that a piping system can per its intended function position retention, leak tightness, operability, or a com- bination in case of design earthquake. seismic function a function to be specified by the engi- neering design either as position retention, leak tight- ness, or operability. seismic interactions spatial or system interactions with other structures, systems, or components that may affect the function of the piping system. seismic response spectra a plot or table of accelerations, velocities, or displacements versus frequencies or periods. seismic restraint adevice intended to limitseismic move- ment of the piping system. seismic retrofit the activities involved in uating the seismic adequacy ofan existing piping systemand iden- tifying the changes or upgrades required for the piping system to per its seismic function. seismic static coefficient acceleration or force statically applied to the piping system to simulate the effect of the earthquake. 1.3 Required a The scope and boundaries of piping systems to be seismically designed or retrofitted. b The applicable ASME B31 Code section. c The classification of piping as critical or noncriti- cal, and the corresponding seismic function position
