Research on the vertical single strut focuses on evaluating support interference values using engineering methods. The singularity method is suggested as a potential approach, though simulation and decomposition of support effects remain unclear. Challenges arise when using the two-step mirror method due to asymmetry between the mirror and main support configurations. Selecting an appropriate angle for the single strut is crucial to minimize interference with the model. Additionally, there is a query regarding the credibility of different wall pressure signature methods.
