Connection design in overseas steel structure projects: why it matters
Connection design is one of the most important parts of overseas steel structure projects. In many international projects, consultants only provide structural loads and member sizes, while the steel contractor must complete the detailed connection engineering. Poor connection design can delay approvals, fabrication, and installation.
