摘要
Abstract
The seismic design criteria in ASME code ,edition 2002 was compared with that in ASM E code ,edition 1995 ,and the intention to derive a less severe design criteria was studied .A conservative factor was defined so that the margin of the design criteria w as evaluated . T he linear and nonlinear response of elbow under seismic loading w as evaluated and the influence of the material nonlinearity ,large deformation and pressure on the response of the elbow was investigated .Based on the results of the elbow under seismic loading ,the margin of the seismic design criteria for the piping in ASM E code was analyzed .The results show that the seismic design criteria for the piping are greatly conservative .关键词
