Basis for Seismic Analysis: The criteria for line selection for seismic analysis are normally mentioned in the ITB documents if the construction site falls under seismic zone. If the same is not mentioned then on a broad respect following lines can be considered: Lines with outside diameter 6” and larger. Transfer line/Two phase flow lines. Strain sensitive equipment: Compressor, Turbine and Pump. Heater and Cold box connected lines. Steam & flare header system in pipe rack. Other lines considered important as per stress engineer’s decision. http://www.whatispiping.com/seismic

Static Method of Seismic Analysis of Piping System using Caesar II – What is Piping
As per code ASME B 31.3 the longitudinal stresses generated due to sustained and occasional loads should be within 1.33 times Sh (Basic allowable stress at hot temperature) value. So We have to add Sustained stress and occasional stress such that the scalar combination of the same remains within the limit specified by the code. Normally the nozzle load checking is not required for seismic analysis. However few companies need the nozzle load checking at seismic condition for static equipments. Sometimes the allowable nozzle load can be increased by 50% for checking in occasional cases. However nozzle load checking is not required at seismic case for rotating equipments. The following article will describe steps to perform the static method of seismic analysis in Caesar II. The first step in static seismic analysis is to collect the seismic coefficient. Sometimes the value of seismic coefficient is provided directly and sometimes enough data is provided to calculate the same. The following equation (as per IS 1893) can be used to calculate the seismic co-efficient:

content/uploads/2014/03/seismic-coefficient.jpg) Caesar Spreadsheet showing the input of Seismic Co-efficient Normally Y component is not entered. However few clients may require the input of the same. in that case follow guidelines provided by them. To perform seismic analysis open the Caesar II spreadsheet and click on uniform loads as shown in the below mentioned figure.
