Analysis of Modified Bolotin Method on maximum deflection of three stiffeners plates

Abstract

Abstract The main goal of this study is to analyze the correlation between the detonation source and the time duration of blast loading and the plate’s dynamic response with the variation of peak pressures. The plate was modeled as a concrete orthotropic plate with semi rigid support at all its sides. Natural frequency can be found with Modified Bolotin Method and the numerical calculation is solved with Mathematica and Microsoft Excel. The results show that the longer the explosion distance, the maximum pressure due to the explosion is smaller and the time that the blast wave needed to reach the plate’s surface will become longer. When the peak pressure of blast loading become bigger, the plate’s dynamic response and deflection will become bigger.
