The purpose of this study is to enable emergency recovery of damage caused by earthquakes in structures and prevent secondary damage by controlling progressive collapse. Although there have been many previous studies using reinforcing bars and meshes, there have been few studies using carbon grid fibers as a substitute for tension members. This study aims to quantitatively present disaster response seismic performance by manufacturing concrete panels with no layers, one layer, or two layers of carbon fiber grids inserted and to compare the flexural strength and energy dissipation capacity. Flexural strength increased by 7% with one layer and 15% with two layers compared with no layer. Energy dissipation capacity increased by 30 times with one layer and by 56 times with two layers compared with no layers, and showed great improvement in terms of seismic performance. Especially because of the large increase in the energy dissipation capacity, the carbon fiber grid reinforcement method is considered to be an effective method for improving seismic performance.

Water losses in irrigation canals occur during the process of water transportation, with seepage loss being the main contributor to total water loss in irrigation conveyance. Cracks and settlement are the most problematic factors affecting canal lining structures, leading to reduced performance of irrigation canals due to issues such as sediment deposition, waterlogging, and leakage. Seepage losses typically range from 20 % - 30 %, but this can be reduced to 15 % - 20 % with the use of canal lining. However, the concrete lining structure, being a thin plate, is prone to high rates of cracking, which weakens the performance of canals. Therefore, it is crucial to enhance the flexure and splitting-tensile strengths of concrete to control the rate of cracking in the canal lining. The splitting-tensile strength of concrete is particularly important in crack control. Hybridization of fibers, such as combining polypropylene and jute fibers, can efficiently enhance flexural toughness, flexural strength, and fracture energy more than using a single type of fiber. The overall aim of this review is to summarize the literature on the use of modern materials to reduce water losses in concrete canal lining. Initially, hybrid fibers (one natural fiber and one artificial fiber) are selected to explain the behavior of hybrid fiber reinforced concrete (HFRC). The crack arresting mechanism of HFRC can help reduce losses in concrete canal lining. The findings of this review will be valuable as a reference for both industry practitioners and academic researchers interested in the development of hybrid fiber reinforced concrete materials, particularly for canal lining applications.

Bài báo sử dụng phương pháp mô phỏng phần tử hữu hạn để khảo sát sự phá hoại cục bộ của tấm bê tông cốt sợi (fiber reinforced concrete – FRC) dưới tác động của tải trọng nổ. Mô hình mô phỏng phần tử hữu hạn của thí nghiệm tấm FRC chịu tác động của khối thuốc nổ được phát triển trên phần mềm LS-DYNA. Kết quả phân tích từ mô hình phù hợp với kết quả thu được từ thí nghiệm chứng tỏ mô hình phần tử hữu hạn có thể mô phỏng tương đối chính xác sự phá hoại của tấm FRC chịu tải trọng nổ. Mô hình phần tử hữu hạn được dùng để khảo sát các yếu tố ảnh hưởng đến sự phá hoại cục bộ của tấm FRC bao gồm vật liệu, kết cấu và tải trọng. Các kết quả phân tích cho thấy rằng mỗi tham số đều có ảnh hưởng nhất định đến sự phá hoại của tấm FRC.
