Abstract: The vent riser is one of the important components of natural gas transportation engineering, that can ensure pipeline safety, and reduce accident risk. Exploring its seismic response under different peak accelerations is of great practical significance for earthquake prevention and disaster reduction work in pipeline projects such as the West East Gas Pipeline. This study combines examples and uses the finite element software ABAQUS to establish a three-dimensional finite element model of the vent riser. Through modal analysis, the natural vibration period of the structure is determined, and then a ground motion with a predominant period similar to that period is selected as the base input. The seismic performance extraction target parameters were used to analyze the seismic response of vent risers under four different peak accelerations of earthquakes. Then, a method for classifying the seismic damage level of vent risers was proposed. It is found that the most vulnerable part of the vented riser is the junction of the pipe wall and the reinforced concrete bearing, which needs to be strengthened. This study can provide a reference for earthquake disaster risk screening of oil and gas transmission vent risers.
