Failure pattern of singe-layer reticulated dome under severe earthquake and its shaking table test
Abstract Based on the constitutive model with considering material damage accumulation, the influence of material damage accumulation on the responses of the structure is investigated in detail through the incremental dynamic analysis method (IDA analysis). The failure pattern of single-layer reticulated dome under dynamic loading is obtained using IDA analysis through multiple sets of seismic load records and harmonic loading, which is identified to be the dynamic instability failure caused by the geometric nonlinearity and the dynamic strength failure resulted by the material nonlinearity. The shaking table tests of single-layer reticulated dome are exploited to verify the failure pattern of the structure under seismic load records. Experimental results show that the plasticity of the model develops and the deformation increases, as well as the mechanical properties weakens continuously with the increasing of the loading value, which indicates that the failure pattern of the structure is dynamic strength failure.
