calculating reaction forces from etabs result

[sazvon]

hi all.

i really need some help here.

how do we calculate the reaction forces from etabs.

i mean, we will look at the design reaction at base which we get from 'display>show table>analysis>result>reaction>design reaction'

so what bothers me is that..do we add up every reaction result from all the different load cases at every nodal?
i.e:

Story Joint Label Load Case/Combo FX
kN
BASEMENT2 63 DEAD 7.6105
BASEMENT2 63 LIVE -0.3715
BASEMENT2 63 WINDX 3.6032
BASEMENT2 63 WINDY 2.8445
BASEMENT2 63 DRIFT1 13.4452
BASEMENT2 63 DRIFT2 4.0769
BASEMENT2 63 DRIFT3 12.4589
BASEMENT2 63 DRIFT4 5.0632
BASEMENT2 63 DRIFT5 11.5335
BASEMENT2 63 DRIFT6 2.1653
BASEMENT2 63 DRIFT7 10.5472
BASEMENT2 63 DRIFT8 3.1516
BASEMENT2 63 UDCon1 10.6547
BASEMENT2 63 UDCon2 8.5381
BASEMENT2 63 UDCon3 14.5261
BASEMENT2 63 UDCon4 2.996
BASEMENT2 63 UDCon5 13.3122
BASEMENT2 63 UDCon6 4.2099
BASEMENT2 63 UDCon7 12.0151
BASEMENT2 63 UDCon8 6.25
BASEMENT2 63 UDCon9 11.4081
BASEMENT2 63 UDCon10 6.857
BASEMENT2 63 UDCon11 12.6145
BASEMENT2 63 UDCon12 1.0844
BASEMENT2 63 UDCon13 11.4006
BASEMENT2 63 UDCon14 2.2983
BASEMENT2 63 UDWal1 10.6547
BASEMENT2 63 UDWal2 8.5381
BASEMENT2 63 UDWal3 14.5261
BASEMENT2 63 UDWal4 2.996
BASEMENT2 63 UDWal5 13.3122
BASEMENT2 63 UDWal6 4.2099
BASEMENT2 63 UDWal7 12.0151
BASEMENT2 63 UDWal8 6.25
BASEMENT2 63 UDWal9 11.4081
BASEMENT2 63 UDWal10 6.857
BASEMENT2 63 UDWal11 12.6145
BASEMENT2 63 UDWal12 1.0844
BASEMENT2 63 UDWal13 11.4006
BASEMENT2 63 UDWal14 2.2983


so the total reaction fx for node 63 is 312.4585kN?

is it?

I thought at the end of the tables it gives you summations. Either that or go

building output>story shear
