2.1 概念：

1. Since the SCR reactor is greater than 25% of the total SCR system, the SCRreactor

should be integrated with the support system for seismic design;2. Consertively adopte the a_ max as the design seismic factor;

3. Regard the SCR reactor have a uniform stiffeness along its height, and eachcatalyst

support beam level will be treated as a mass;

4. Base shear method is applied; the amplification for top mass is ignored due to theheight of SCR Reactor is quite lower than the SCR supporting steel;5. Overburden Load assign to top level and bottom level respectively.
