Title: TESTING AND ANALYSIS OF HEAVY DUTY RIVETED GRATINGS
Author: Bejgum, Mahesh
Description: Metal bar gratings have been used in engineering and architectural applications for more than 80 years. Current design provisions are based on the allowable stress design philosophy using a simple mechanics approach for engineering analysis. Previous research and field experience with bar gratings has shown that the present design procedure is somewhat over-conservative, possibly resulting in uneconomical design of the gratings. There is a need to examine the behavior and current design approach of riveted steel bar gratings due to improvements in design methodologies, as well as market pressure from new materials and forms of gratings. Development of finite element software has made the building and processing of models easy and efficient. The ability to make rapid changes to the models has made the use of the finite element method for analyzing and studying the behavior of the metal bar gratings possible. This study involved the testing of heavy duty riveted and welded metal bar gratings. Finite element models were developed for riveted gratings using ANSYS 9.0. Linear analysis was performed on the models developed for design loads. Nonlinear analysis was performed, and incorporated both geometric and material nonlinearities to find the collapse load of the grates. Deflections obtained from the lab tests were compared to the results obtained from the finite element analysis to judge the accuracy of the models. Design recommendations were developed.
