Parametric Analysis of Reinforced Concrete Beams Under Blast Load

In order to Resolve LongAnalyze and Design and Provide an Easy and accessible Method for Calculating the Response of Concrete Beams to Explosion Load, the Dynamic Analysis Method for One Degree of Freedom System has been used to Analyze this Structure and its Deflection. To Obtain the Answers, the Explosive Load is used exponentially and the Behavior of the Concrete Structure is Considered Elasto-Plastic Equivalent. Then, using two Parameters of Load Duration and Time to reach the End of the Elastic Region to Determine the Range of Responses, Different Modes have been Considered to Calculate the Response Equation and Determine the Maximum Deflection of the Concrete Beam by Theoretical Analysis of SDOF Equations of Motion for the Specified Ranges, the Parametric Responses of Concrete Beams to the Explosion Load were Obtained. Finally, by Comparing the output of these Relationships with the Results of Laboratory Tests, the Finite Element Model and the Relationships of the UFC 3-340-02, the Accuracy of the Proposed Method is Ensured. By Performing different Analyzes in Different Loading Condition and Different Structural Properties, It Was Founf that the Accuracy of the Propoesed Method Is above 90%.
