An analytical study using a non-linear finite-element method was carried out to evaluate the effect of the shape and spacing of shear studs on the behaviour of steel-plate–concrete walls subject to blast loads. The size of the analytical model was determined by reference to an existing literature review and code requirements (Kepic-SNG). The analytical model was validated against experimental results. The behaviour of a wall subject to blast loading was then analysed for various stud spacings and shapes. As found in previous research, the maximum deflection increased as the spacing of studs increased and the time when the maximum deflection occurred was delayed. Improved studs were found to be effective in reducing displacement when arranged at lengthwise spacings of 100 mm or more.

承受爆炸载荷的钢板混凝土墙的改进螺柱布局

进行了使用非线性有限元方法的分析研究，以评估抗剪栓钉的形状和间距对爆炸荷载作用下的钢板混凝土墙性能的影响。分析模型的大小是通过参考现有文献综述和法规要求（Kepic-SNG）确定的。分析模型已针对实验结果进行了验证。然后分析爆破载荷作用下的墙体的行为，以了解各种螺柱间距和形状。如先前的研究发现，最大挠度随着螺柱间距的增加而增加，并且最大挠度发生的时间被延迟。发现当以100mm或更大的纵向间隔布置时，改进的螺柱可有效减少位移。
