For the sports building:
5.11.6 Concurrent Seismic Effects
The procedure is similar to that in Section 5.5.4.

5.11.7 Actions Calculations
The procedure is similar to that in Section 5.5.5.

5.11.8 Overturning Effects

The procedure is similar to that in Section 5.5.6. As the results of the evaluation
of the overturning effects presented in Table 5.34 show, the retrofitted buildings
adequately resist the overturning moments.

5.11.9 Modeling Assumptions
The procedure is similar to that in Section 5.5.7. The plastic hinge characteris-
tics of different structural members of the retrofitted buildings are shown in
Figs. 5.33–5.36.

5.11.10 Capacity Forces Calculations
5.11.10.1 Linear Static Procedure
Beams
The procedure is similar to that in Section 5.7.1.1.

Columns
The procedure is similar to that in Section 5.7.1.2. The lower-bound axial capac-
ities of columns in the retrofitted buildings are presented in Table 5.35.

5.11.10.2 Nonlinear Static Procedure
The procedure is similar to that in Section 5.7.2.

5.11.11 Acceptance Criteria
The procedure is similar to that in Section 5.8.

5.11.12 Results

Examples of the results of nonlinear static analysis on the main retrofitted build-
ing are shown in Figs. 5.37 and 5.38 and Tables 5.36 and 5.37. The example
