无加劲钢板剪力墙是一种有效而经济的结构抗侧力措施。结构工程师需要能够使用常规的分析软件来评估钢板剪力墙的非弹性结构响应，该分析软件通常是可用的，并且使用起来相对简单和迅速。条带模型是钢板剪力墙分析中一种被广泛接受的分析工具，本文根据钢板剪力墙在实验室加载过程中观察到的现象对条带模型进行了改进。由于最初的条带模型是作为一种弹性分析工具提出的，因此这些改进主要是为了实现壁的屈服和最终劣化的准确表示，尽管也对初始刚度预测进行了适度的改进。在评估每一个建议的改进，建模效率进行评估的解决方案的准确性。使用修改后的带模型的参数研究检查的影响，改变倾斜角度的张力带上的预测模型的非弹性行为。值得注意的是，它被发现的极限承载力的钢板剪力墙模型与各种各样的配置变化不大的变化的倾斜带。
Unstiffened steel plate shear walls are an effective and economical method of resisting lateral forces on structures due to wind and earthquakes. Structural engineers require the ability to assess the inelastic structural response of steel plate shear walls using conventional analysis software that is commonly available and is relatively simple and expeditious to use. The strip model, a widely accepted analytical tool for steel plate shear wall analysis, is refined based on phenomena observed during loading of steel plate shear walls in the laboratory. Since the original strip model was proposed as an elastic analysis tool, these refinements are made primarily to achieve an accurate representation of yielding and eventual deterioration of the wall, although moderate improvements in initial stiffness predictions are also made. In assessing each of the proposed refinements, modeling efficiency is evaluated against the accuracy of the solution. A parametric study using the modified strip model examines the effect of varying the angle of inclination of the tension strips on the predicted inelastic behavior of the model. Notably, it was found that the ultimate capacities of steel plate shear wall models with a wide variety of configurations vary little with the variation of the inclination of the strips.
