Vehicle Load Analysis

The main objective of Vehicle Load Analysis for pipeline is to ensure the object’s integrity and stability during the maximum impact acting on the surface.

The dynamic loads are applied on the object surface and its material behavior will be studied precisely by using Finite Element analysis methods. Based on the material type, the relevant software application will be placed as per project requirements. The first step of the Vehicle Impact Analysis is to perform the Input Analysis and validate the data from input documents. Based on the data validation various vehicle impact methods are analyzed.

Input data for Pipeline modelling is filled in including Soil Properties in STAAD FEM Software. After running the model, the Pipeline maximum allowable vertical load is evaluated along with load on the Pipes with actual Soil load. This is followed by the implementation of Vehicle Load Value (with impact factor) based on the frequency of the Vehicle movement. The model simulation results are analyzed for various loads in different depths of the corridor. The results are then assessed on the basis of if Actual Load is less than MAVL. If yes, the design is considered Safe.

If Actual load is greater than MAVL, the analysis will be performed for a different depth of cover following which a safe depth of cover will be recommended along with the summary of the results

The flow chart depicts the input analysis & data validation of vehicle load analysis. Model simulation result analysis is obtained through passing it to the appropriate software.
