Stiffened plates form the backbone of most of a ship's structure. They are, by far, the most commonly used structural elements in a ship, appearing in decks, bottoms, bulkheads and side shells. Stiffened plates are widely used because of their simplicity to fabricate and excellent strength-to-weight ratio. Today, finite element (FE) models are used to analyze the behavior of such structural elements for different types of loads. In the past, when use of computers and the FE models were not very much in use, analytical analysis methods were required. The analysis of a stiffened plate, subjected to lateral loading, was based on one of two different types of models, namely, the orthotropic model and the grillage model. Both models estimated the maximum plate deflection under uniform lateral pressure. The objective of this paper is to implement an orthotropic model, on the basis of a series of papers published by H. A. Schade, as an algorithm/computer program for a fast structural analysis, without the aid of sometimes cumbersome finite element techniques. This will allow the user to quickly check if a plate can withstand applied loads, without the need to build the FE models, and to improve it if necessary (e.g., using more stiffeners or greater thickness).
