Stability Analysis on Truss Overhead Crossing Structure of Oil and Gas Transmission Pipeline
For the problems of truss overhead crossing design of oil and gas transmission pipeline, based on original truss design proposal of Zhijing River and practical need of the project, critical load of bars are determined by classing structure members. Using finite element method (FEM) analysis program, ANSYS, stability analysis of 12 truss models under such possible limit loads as earthquakes, temperature change, wind-force, weight of truss and pipe and pressure test is made. Comparing stability with strength and rigidity, safety of the trusses are analyzed. The results show that buckling danger of models is mainly at upper string bar of middle truss. The danger levels of buckling and rigidity losing effectiveness are not lower than that of strength damage.
