| Popis: |
A series of multi-bay steel grillages were tested to collapse in the Grillage Test Fixture at the U.S. Naval Academy. The grillages were nominally 1/3-scale models of typical warship deck structures. The tests were part of a student research project investigating reliability-based design methods for stiffened panels. The six nominally identical grillage specimens were made from ordinary steel and consisted of three panels (bays) stiffened longitudinally and transversely with T-shaped stiffeners. Three specimens were tested under in-plane loads only, and three were tested with a combination of in-plane loads and initial lateral pressure. During testing data were collected from strain gages and displacement transducers to quantify the structural behavior of the specimens under load. Theoretical predictions of failure mode and stress level are compared to observed values. The test results are also compared to results from similar tests conducted at other facilities. A finite element method analysis of the grillages subjected to compressive axial load was conducted using ABAQUS and the results compared to the test results. The data from past tests and these tests are used to evaluate the accuracy of theoretical predictions over a wide range of test conditions. |
