Abstract

In the context of steel composite wall (SC wall) standards, this study explores the relaxed provisions outlined in AISC N690 (2018), particularly concerning commonly used materials in general building construction, such as faceplate thickness, concrete strength, shear connector spacing, and steel tie spacing. These provisions were then applied to assess the viability of a “relaxed steel composite wall” as a seismic force-resisting system suitable for mid- and low-rise structures. Experimental investigations were conducted to achieve these objectives. A dedicated SC wall specimen was constructed, and various variables were examined, including the presence or absence of shear connectors, shear connector spacing, steel tie spacing, and faceplate types. The results were analyzed to assess fracture behavior, the relationship between shear force (V) and transverse displacement (Δ), shear stiffness variations, maximum in-plane shear strength, displacement ductility ratio (μ), and energy dissipation characteristics. Moreover, their displacement ductility ratios remained below 10, and they exhibited substantial energy dissipation capabilities. These findings suggest that the application of “relaxed SC walls” as seismic force-resisting systems is feasible for mid-, low-, and high-rise structures.

钢混结构墙体结构和抗震性能验证实验研究

摘要在钢混墙（SC 墙）标准的背景下，本研究探讨了 AISC N690（2018 年）中概述的放宽规定，特别是有关一般建筑施工中常用材料的规定，如面板厚度、混凝土强度、剪力连接器间距和钢拉杆间距。然后应用这些规定来评估 "松弛钢复合墙 "作为适用于中低层结构的抗震系统的可行性。为实现这些目标，我们进行了实验研究。我们制作了一个专用的 SC 墙体试样，并对各种变量进行了研究，包括是否存在剪力连接件、剪力连接件间距、钢拉杆间距和面板类型。对结果进行了分析，以评估断裂行为、剪力 (V) 与横向位移 (Δ)之间的关系、剪切刚度变化、最大平面剪切强度、位移延性比 (μ)，以及能量耗散特性。此外，它们的位移延性比保持在 10 以下，并表现出很强的消能能力。这些研究结果表明，在中、低、高层建筑中应用 "松弛 SC 墙 "作为抗震系统是可行的。
