Abstract

The dynamic response of the liquid storage structure (LSS) under explosion-induced ground shock is highlighted in engineering protection. Establishing a dynamic similarity relationship between the structural model and its prototype is essential for enhancing the quality of the experimental investigations. The conditions necessary for achieving similarity were derived through dimensional analysis. Additionally, the equation analysis method was employed to determine the similarity laws governing the dynamic characteristic parameters and responses. Two-way fluid-structure interaction finite element models were developed to validate the accuracy of the similarity criterion. The findings indicated that critical response parameters, including structural deflection, hydrodynamic pressure, and structural strain, adhere to the established similarity laws when the material properties, dimensions of the LSS, and the ground shock parameters meet the requisite similarity conditions. Based on the similarity criterion, the response results obtained from the model LSS can be quantitatively extrapolated to the prototype.

期刊介绍： Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses. Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering. The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
