Abstract

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.
