  • To ensure BATS’s dynamic

performance

  • Two static loading cases:

(1) 60 MN vertical compressive force (2) 55 MN vertical compressive force and 3900 kN longitudinal force

  • Maximum principle stress at

interface between foundation and reaction frame < 30 MPa

  • Maximum principle stresses of

cross beam are 246 MPa for case 1 and 226 MPa for case 2 Reaction Frame Foundation
