I, II, III. Table 1 SNIP II-7-81*, table 1 SP 14.13330.2018, appendix 1 NP-031-01 |
Vertical
seismic acceleration factor |
Equal to the correlation of maximum (peak) vertical soil acceleration and maximum (peal) horizontal soil acceleration. Set based on seismic microzoning data. In the absence of data, should be set as 0.7. More... |
