Structural Strength and Buckling Analysis for a Steel Derrick after its Members Removed Partly

Abstract:

The static strength and stability of a derrick structure (78.5m high) after its members removed partly are researched. The derrick is modeled by three-dimensional spatial beam elements based on ANSYS. By the static analysis, the strength of the derrick after its member removing partly is larger than that of the original derrick structure since some loads disappear. From the buckling analysis, it can be found that the stability reduces drastically when removing some members.
