Modern architecture is rapidly evolving toward greater multifunctionality and integration. However, significant differences in vertical functional zoning or varying spatial requirements within the same building often result in mismatches between the column grids of upper and lower floors. In response, our company, in collaboration with the East China Architectural Design & Research Institute Co., Ltd., has conducted technical research and process innovation to develop a construction technique for non–drop-in short steel beam–column transfer nodes that is specifically suited to such scenarios. This technology has undergone scientific and technological achievement appraisal and has been recognized as being at an internationally advanced level overall, earning one Zhejiang Provincial Science and Technology Achievement Award (Registration No.: DJ101002023Y0477). During construction, we also filed and obtained a patent entitled “Temporary Support System for Steel Structures” (Patent No.: 202222496709.8). The proposed technique employs an optimized node design in which short steel members are pre-embedded within concrete beams to facilitate connections, thereby eliminating the need for continuous-length steel members and achieving a refined “strong-node, weak-member” structural configuration. Practical application in projects has demonstrated that this construction method significantly reduces steel consumption, optimizes rebar splicing, and simplifies on-site operations. The “New Construction Method for Non–Drop-In Short Steel Beam–Column Transfer Nodes” was awarded the “2024 Zhejiang Provincial Outstanding Provincial Construction Method” honor.
