Abstract
The welded end-slot buckling restrained brace (WES-BRB) was developed in the National Center for Research on Earthquake Engineering (NCREE). The WES-BRB can offer a cost-effective solution to meet inter-story drift limit and earthquake resistant requirements for seismic steel buildings. In order to optimize the designs of the WES-BRB components and connections, an innovative cloud service named Brace On Demand (BOD) has been constructed in NCREE. The BOD server hosted in NCREE provides the up-to-date and on-demand service for users to effectively find the complete design of the WES-BRBs and connections meeting all seismic design requirements. Users are only required to enter the frame geometry and the BRB yield strength in the BOD browser, and then the BOD server can immediately compute and report the results including all the detailed dimensions of the WES-BRB, gusset and weld sizes. The results, including structural calculations and drawings in .xls and .dwg format, can be downloaded and conveniently incorporated into the construction documents. The BOD is able to provide a very time-saving and cost-effective tool for structural engineers in the seismic design of building projects using WES-BRBs. The detailed development and key features of the BOD are illustrated in this paper.
