LOADS AND COMBINATIONS :

Loads :

G         : Dead Load
Q         : Live Load
Qr        : Roof Live Load
S         : Snow Load
R         : Rain Load
W        : Wind Load
E         : Seismic Load
T          : Temperature Change
 
Combinations:

1.   G
2.   G + Q
3.   G + ( Qr or S or R )
4.   G + 0.75Q + 0.75( Qr or S or R )

        (5a) G +1.0W
        (5b) G + 0.7E                                                                            (9.1b)
        (6a) G + 0.75Q + 0.75( Qr or S or R ) + 0.75W
        (6b) G + 0.75Q + 0.75S + 0.75(0.70E)                                     (9.1a)
        (7)  0.6G + W
        (8)   0.6G + 0.7E                                                                       (9.1c)
 
         - T temperature change effects will be taken in all combinations with ± 0.75 coefficient which will increase the required strength.
 
        - Ed (H) = ±Ed(X)        ± 0.30Ed(Y)                  (horizontal earthquake effect)         (4.9)
        - Ed (H) = ±0.30Ed(X) ± Ed(Y)                        (horizontal earthquake effect)          (4.9)
        - Ed(z) = (2/3) Sds.G olarak alınır
        - Ed = Ed(H) ± 0.30 Ed(Z)               (horizontal + vertical earthquake effect)          (4.11- 4.12)
