Abstract
This paper considers the seismic resistance of buckling restrained braces (BRB) in single-layer reticulated domes and their substructures. The method of tracing the full-range dynamic response is used to analyze the seismic response of dome structures with different embedded braces. Based on results relating to critical responses, such as displacement, development of plastic deformation and ultimate load, the effect of BRBs on key design parameters, including core area, yield stress, installing forms etc., is examined. The effect of a dome’s rise-span ratio on the structure is also investigated. It is concluded that BRBs between supporting columns can effectively improve a structure’s seismic performance.
