Gas protective walls are safety elements that can withstand the pressure of fires or explosions caused by gas leaks, thus preventing the spread of explosion damage to other facilities or operators. However, in the new construction or expansion of gas facility rooms in existing buildings, the barrier must often be built even if it does not satisfy the legal standards regarding the accepted construction methods. In these cases, the gas barrier for the existing building should be constructed by the new construction method using chemical anchor bolts. However, no performance evaluation data or reliable engineering verification results are available for the entire gas facility room based on actual experiments. In this study, based on a review of regulations on gas barriers, the protective performances of the new barriers were compared in terms of displacement, rotation angle, rebar strain, and yield value of the concrete surface through actual strength demonstration experiments. Based on these results, the protection performance of an entire gas facility room that could not be constructed and tested in real time was evaluated by a fluid structure interaction (FSI) analysis using the TNT(Trinitrotoluene) equivalency method and three-dimensional AUTODYN.

气体防护墙是可以承受由气体泄漏引起的火灾或爆炸的压力的安全元件，从而防止爆炸对其他设施或操作人员的扩散。但是，在新建或扩建现有建筑物的气体设施室时，即使不满足有关公认的建造方法的法律标准，也必须经常建造障碍。在这种情况下，应使用化学锚栓通过新的施工方法为现有建筑物建造阻气层。但是，根据实际实验，没有整个燃气设施房间的性能评估数据或可靠的工程验证结果。在这项研究中，基于对气体屏障法规的审查，通过实际强度演示实验，从位移，旋转角度，钢筋应变和混凝土表面屈服值等方面比较了新屏障的防护性能。基于这些结果，通过使用TNT（三硝基甲苯）当量法和三维AUTODYN的流体结构相互作用（FSI）分析，评估了无法实时建造和测试的整个燃气设施房间的防护性能。
