Abstract
Nuclear power plants, where steel-plate concrete (SC) structures are commonly adopted, require large-scale components to withstand significant loads, such as those caused by sudden explosions. As a result, SC modular members used in nuclear power plants must have thicker walls filled with concrete compared to standard-sized ones. These large walls also require additional components, such as tie bars and H-shaped steel sections, to reinforce adhesion and resist shear stresses. This study focuses on tie bars placed adjacent to studs and evaluates their influence on the tensile strength of wall structures. To investigate this, we conducted experimental tests using full-scale specimens, including various combinations ranging from single stud to combined stud-tie configurations. Based on the results of these performance tests, we propose a design recommendation for estimating the tensile capacity of SC structures, considering the influence of tie bars.
核电站通常采用钢板混凝土（SC）结构，需要大型构件来承受巨大的荷载，例如突然爆炸造成的荷载。因此，与标准尺寸的钢板混凝土结构相比，核电站中使用的钢板混凝土模块构件必须有更厚的混凝土填充墙。这些大墙还需要额外的部件，如拉杆和 H 型钢，以加强粘附力和抵抗剪应力。本研究重点关注与墙柱相邻的拉杆，并评估其对墙体结构抗拉强度的影响。为此，我们使用全尺寸试样进行了实验测试，其中包括从单一龙骨到组合龙骨-拉杆配置的各种组合。根据这些性能测试的结果，我们提出了考虑拉杆影响的 SC 结构抗拉强度估算设计建议。
期刊介绍：
Materials (ISSN 1996-1944) is an open access journal of related scientific research and technology development. It publishes reviews, regular research papers (articles) and short communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Materials provides a forum for publishing papers which advance the in-depth understanding of the relationship between the structure, the properties or the functions of all kinds of materials. Chemical syntheses, chemical structures and mechanical, chemical, electronic, magnetic and optical properties and various applications will be considered.
