As shown in the figure, an ASME vessel was designed; in PVELite’s “Seismic Data” section, GB 50011-2011 \"Code for Seismic Design of Buildings\" was chosen as the design standard. In the “Seismic Data” field, there are options such as “Percent Seismic for Hydrotest” – the percentage of seismic load to be considered during hydrotesting, “Alpha 1 from 5.1.4” – the seismic coefficient value, and “DeltaN from 5.2.1 if applicable” – the additional seismic coefficient. 1. The definition of the “Alpha 1 from 5.1.4” seismic coefficient value in PVELite is as shown in the diagram; whereas according to the definition in GB 50011-2011 \"Code for Seismic Design of Buildings\" section 5.1.4, the “Alpha 1 from 5.1.4” seismic coefficient value is determined as indicated in Figure 5.1.4-1. 2. The definition of the additional seismic coefficient “DeltaN from 5.2.1 if applicable” in PVELite is as shown in the diagram. 3. The “Percent Seismic for Hydrotest”, which represents the percentage of seismic load to be considered during hydrotesting, is not defined by any relevant standards. Now, the question is: if it is necessary to simulate an earthquake of magnitude 8, how should the “Alpha 1 from 5.1.4” seismic coefficient value be determined? Should the values be taken from the table in 5.1.4 of GB 50011-2011 \"Code for Seismic Design of Buildings\"? 2. How should the value of the additional seismic coefficient “DeltaN from 5.2.1 if applicable” be determined? 3. “Percent Seismic for Hydrotest”: How should the percentage of seismic load contribution during a hydrotest be determined?
