Pipeline seismic resistance
Thread Content
I would like to ask the experts here: for the design peak ground velocity in seismic calculations for pipelines, how is this value determined? Is it based on values measured from past earthquakes, or are there empirical values that can be used?
In the seismic design of pipelines, the value of the peak velocity of the design ground motion can be determined based on factors such as the local history of seismic disasters, seismic intensity, and soil conditions. Under normal circumstances, it is recommended to carry out the calculations in accordance with the requirements of ** or the relevant regional regulations. For example, in China, according to the Code for Seismic Design of Buildings (GB50011-2010), appropriate seismic motion parameters must be selected for calculations based on the local earthquake intensity and site classification. These parameters include the earthquake group coefficient, design spectrum coefficient, site classification coefficient, and seismic action direction coefficient. Therefore, the selection of a value requires comprehensive consideration of multiple factors. .
