| Abstract: | To research the dynamic behaviour and earthquake response of a large span conoid shell, dynamic test was carried out of the textil mill with 36m span conoid shell in Pingyao Shanxi. Three methods were used, they were mechanic harmonic excitation, shock excitation and pulsation. We obtained a large amount of test date. Through analysis, we obtained the nature frequen cies, mode shapes and critical damping of the building. The boundary conditions in junction between old and new building and the shock resistance of the structure were researched. |
