The use of modular structures involves the rapid on-site assembly of members that were pre-manufactured in a factory. Research into this approach has recently been increasing owing to its lower cost, afforded by the shortened assembly process. In this study, we evaluate the use of developed blocks with improved welding, developed through previous research, to improve existing connections' structural performance. The newly-developed connection exhibited superior structural performance over existing connections. This developed block will enable a size reduction of members during their design and is anticipated to yield economic benefits. In addition, the reliability of a connection analysis method using the developed block was proved by using ABAQUS, a general-purpose finite element analysis program. Furthermore, a review of the panel zone design method was conducted through additional variable analysis. No structural problems were found to occur, even with the use of an existing design formula. Therefore, the panel zone design equation is deemed sufficient when designing the developed block.

模块化结构的使用涉及在工厂预先制造的构件的快速现场组装。由于缩短了组装过程，降低了成本，因此最近对这种方法的研究不断增加。在这项研究中，我们评估了通过先前研究开发的具有改进焊接的开发块的使用，以改善现有连接的结构性能。新开发的连接表现出优于现有连接的结构性能。这个开发的区块将能够在设计过程中减小构件的尺寸，并有望产生经济效益。此外，通过使用通用有限元分析程序 ABAQUS 证明了使用开发块的连接分析方法的可靠性。此外，通过附加变量分析对面板区域设计方法进行了审查。即使使用现有的设计公式，也没有发现结构问题。因此，在设计开发区块时，面板区域设计方程被认为是足够的。
