M DEV ≥ 0.75 M o                                            (4.3)

Possible solutions:

  • A curtain Shearwall / curtain shearwall group can be added to the carrier structural system until the Equation 4.3 condition is met.

  • The structure can be designed by choosing high ductility level instead of limited.

...

  • M DEV = In reinforced concrete and steel composite structural systems, the sum of the tipping moments caused by earthquake loads at the base of the reinforced concrete walls with high ductility level bond beam (with or without gaps) and central, eccentric or buckling-prevented steel braced frames

    M o = Total tipping moment at the base from earthquake loads for the entire building
