A heavy-duty riveted steel grating is a lightweight and easy to install open grid bridge deck system used primarily in movable bridges. These systems may increase the load carrying capacity of the bridge deck because of the decrease in the dead weight of the structure. Initially, bridge decks were analyzed according to the principles used in the design of railways, but with the industrial revolution in the 19th century and the increasing need for more bridges for transportation, a precise method for analyzing bridge decks was needed. Empirical methods were available and used by the bridge engineers until `Bridge Deck Behavior’ was issued by E.C. Hambly (1976). Many improvements were made with research focused on bridge decks and new methods of analyzing deck systems came to light. There is no method that is simple, yet accurate that can be used at a desk by engineers. The current research focuses on representing a bridge deck system by a grillage model and studying its behavior under static H20 truck (AASHTO H20) loading along with a 30% impact factor. Grillage analysis is one of the methods to represent the bridge structure with a grillage formed by two-dimensional discrete grillage members representing the main bearing bar members. Experimental results from the tests conducted on two panels of R-37-5 (5”x3/8”) Lite Steel Gratings are compared to the results from the model analysis results from SAP2000 v17. Static behavior of the riveted gratings, as well as stress patterns were investigated using grillage analogy principles. Two different models were prepared in SAP2000 using the principles of grillage analysis to demonstrate the importance of reticuline bars. Based on the comparison, guidelines to model grating for grillage analysis are given and these guidelines are used to estimate the stress patterns and deflection values of a grating with different cross-sectional dimensions and different span. The idea is to demonstrate that grillage analogy can be used to predict the behavior of a riveted steel grating.
