Instead of R (4/5) R should be taken.

The Complete Message:

In the article 4.3.2.4 of TBDY 2018 , two conditions defined in (a) and (b) below are specified in any direction in buildings with reinforced concrete curtain and / or steel braced frame with DTS = 1, 1a, 2, 2a .

(a)   a single pitch bearing system or steel receives base stall torque of the bracing frame M _DEV , then the total floor tilting moment occurring in seismic loads for the entire building in the direction M _o ^' s third is no greater than.

(b)  Construction each side axles located screen / screen or steel braced frame / receives base overturning moment of the frames M _DEV or M _DEV 'the sum of all, that the direction in total floor tilting moment occurring in seismic loads for the entire building M _o ^' s 1 It will not be less than / 6.

One of these conditions are not satisfied, it is in line with the Structural Behavior Factor R instead of (4/5) R will be considered.

Possible solutions:

• By adding a sufficient proportion of curtain / curtain group and side curtain, after the repetition of the analysis, the above-mentioned (a) and (b) conditions are met.

• If the conditions (a) or (b) are not met, the "(4/5) R apply" option in the Analysis Settings / TBDY Options Tab is marked in the requested direction and the analysis is repeated.
