爆炸災害對建築結構造成嚴重破壞，對此領域的研究上缺乏有系統性的規範，因此對結構的抗爆分析變得更加迫切。
本研究將針對：炸藥爆炸後其爆炸壓力波在無限域空間中的傳播進行模擬，並將數值模擬結果與經驗公式計算結果進行比較，驗證分析的可靠性。以及研究不同炸藥量的爆炸荷载對鋼筋混凝土板的破壞分析，找出破壞的情形。對爆炸荷載作用下鋼筋混凝土板破壞影響因素如鋼筋比、炸藥距離、混凝土強度進行分析，找出這些因素影響之規律。
研究結果顯示，高強度混凝土與鋼筋配筋率的降低，對結構系統的最大撓度與破壞情形能有效改善。
最後整理歸納，以提供未來相關學術研究及工程應用上之參考。

Blast can cause serious damage to building structure as well as heavy loss of live and property. It is increasingly necessary and in fact required to carry out extensive research in this field when increased terrorism and local conflicts become worse. The terrorist explosion activities are increasingly concerns which could harm the national security and the social stability. The blast effect on buildings is of widely interest to researchers and engineers all over the world. Accordingly, this study to the nonlinear finite element software LS-DYNA, by select adequacy the material parameters and equation of state (EOS) to perform numerical computation related to the explosive detonates in free air. And then to examine the dynamic characteristics of the reinforced concrete structures. The results of this study provide a valuable reference for engineering designers and researchers to precede the structural dynamic analysis.
