In this study, two types of prefabricated steel structures with a new type of semi-rigid connection were investigated, and the effects of prestressed cable and wall panel were evaluated. A semi-rigid connection test was carried out to evaluate the rotational properties, and the initial cross-sections of structural components were optimized using a proposed optimization program. The prefabricated high-rise structures were significantly affected by the bending properties of semi-rigid connections, and the stiffness of the steel frame was found to be much more significant than that of modular structures. This proposed method provides a theoretical supplement to the design code of steel modular structure.

在这项研究中，研究了两种具有新型半刚性连接的预制钢结构，并评估了预应力电缆和墙板的作用。进行了半刚性连接测试以评估旋转性能，并使用提出的优化程序对结构部件的初始横截面进行了优化。预制的高层结构受到半刚性连接的弯曲特性的显着影响，并且发现钢框架的刚度比模块化结构的刚度要重要得多。该方法为钢结构模块化设计规范提供了理论补充。
