Direct integration mode superposition: a simple method for dynamic analysis of submerged floating tunnel (SFT) / Jamiatul Akmal ... [et al.]

This article describes the use of simple methods to analyze the dynamic behavior of large-dimensional structures, such as submerged floating tunnels (SFT). Using this method the calculation process becomes simple and inexpensive because the solution can be obtained analytically. Based on the superpo...
