In order to ensure the stability of single-layer lattice domes, it is investigated the load-displacement curve for the geometric and material nonlinear analysis of lattice domes considering the condition of elasto-plastic connection. One of the most effective methods to reduce the earthquake response of lattice domes is to install the lead rubber bearing isolation system at the support of a dome. The authors investigated the reducing effect for the seismic response of 100m spanned lattice domes with low rise/span ratio. The lattice dome with LRB isolation system can greatly reduce the dynamic response of domes by extending the period of structures and concentrating of seismic demand at isolation device.
