The recent earthquake damage has highlighted the importance of performance-based design and functional resilience of nonstructural components. Directing at seismic bracings used in piping systems, the construction and design procedure of seismic bracings is introduced in present paper at first. The seismic code requirements and relevant seismic research of bracings are also reviewed. The shaking table test of seismic bracings in a 6-meter full-size piping system is conducted. In addition to theoretical analysis, the seismic performance and failure mode of seismic bracings are studied. The results indicate that failure of bracings in piping systems is mostly due to the bolt looseness in connection components, and the longitudinal response of pipes is basically identical to the floor response. Based on the results, both technical improvement measures to enhance weak connections and design optimization suggestions considering cost are put forward. The use of real-time monitoring in bracings may be an effective way in condition-based maintenance.

The book focuses on seismic design of industrial structures to limit earthquake damage to these safety critical systems, delves into geotechnical aspects related to earthquake design of structures, systems and components (SSC) and offers an introduction to retrofitting and seismic response control...

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 the seismic zone. If the same is not mentioned then on 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

Seismic analysis of piping systems has been reviewed based on the single degree response spectrum curve technique and lumped mass parameters. Using th…
