Abstract: 
In this study, two full-size concrete walls were tested and analyzed to demonstrate the effectiveness of a chemically reactive enamel (CRE) coating in improving their mechanical behavior under blast loading: one with CRE-coated rebar and the other with uncoated rebar. Each wall was subjected in sequence to four explosive loads with equivalent 2, 4, 6-trinitrotoluene (TNT) charge weights of 1.82, 4.54, 13.6, and 20.4 kg. A finite element model of each wall under a close-in blast load was developed and validated with pressure and strain measurements, and used to predict rebar stresses and concrete surface strain distributions of the wall. The test results and visual inspections consistently indicated that, compared with the barrier wall with uncoated reinforcement, the wall with CRE-coated rebar has fewer concrete cracks on the front and back faces, more effective stress transfers from concrete to steel rebar, and stronger connections with its concrete base. The concrete surface strain distributions predicted by the model under various loading conditions are in good agreement with the crack patterns observed during the tests.

活性瓷釉涂层钢筋混凝土防护墙抗爆性能研究

目的:活性瓷釉涂层能够显著增强钢筋的防腐蚀能力,同时能够明显提升钢筋与混凝土的粘结力。通过对活性瓷釉涂层钢筋混凝土防护墙在冲击荷载作用下的破坏特征进行试验和数值模拟,为活性瓷釉涂层技术在钢筋混凝土结构中的应用提供理论基础。
创新点:1. 对活性瓷釉涂层钢筋混凝土防护墙进行爆炸荷载作用下的破坏试验;2. 通过数值模拟,探究活性瓷釉钢纤维对钢筋混凝土结构抗爆能力的影响,为结构设计提出建议。
方法1. 通过对活性瓷釉涂层钢筋防护墙进行爆炸试验(图2),揭示活性瓷釉涂层钢筋混凝土结构的动力破坏特征(图4和5);2. 通过数值方法研究活性瓷釉涂层对钢筋混凝土防护墙抗爆性能的影响,揭示在不同钢筋-混凝土粘结强度时钢筋混凝土结构整体性的变化规律(图10、13和15);3. 在爆炸试验和数值分析基础上,提出活性瓷釉涂层钢筋混凝土结构抗爆设计建议(图16)。
结论:1. 活性瓷釉涂层能够显著改善钢筋在混凝土结构中的传力性能;在爆炸荷载作用下,涂层钢筋混凝土结构的破坏程度明显减轻。2. 活性瓷釉涂层能够显著改善钢筋混凝土结构的变形特性,并显著增强其耗能能力。3. 在采用活性瓷釉涂层进行抗爆设计时,采用直径较小的钢筋可提高结构的吸能能力。
