Dear all,
Three options are available when export floor from Etabs-2013 to safe-v14
EXPORT FLOOR LOADS ONLY
EXPORT FLOOR LOADS AND LOADS FROM ABOVE
EXPORT FLOOR LOADS PLUS COLUMN AND WALL DISTORTION
CSI recommends option number 3 when solving under lateral load, please refer to the...
Dear all,
Etabs2013 asks for system over-strength factor when assigning seismic forces using ASCE-7-05,the program mentioned that this value is used solely in design.
Referring to (ASCE 7-05 Section 12.3.3.3) Required strength of columns supporting discontinuous vertical elements the design of...
i found the answer, referring to ASCE-7-10 Table 1.5-2 Importance Factors by Risk Category of Buildings and Other Structures for Snow, Ice, and
Earthquake Loads
Iw FOR WIND = 1 FOR ALL RISK CATEGORIES
Dear all,
[highlight #FCE94F]The wind speed in ASCE-7-10 is given at the strength level value. This differs from previous editions
of the ASCE Standard where service level values were used. ASCE 7-05 design wind
speeds are multiplied by (1.6)0.5 to convert to ASCE 7-10 design wind speeds. ASCE...

dear inggelu,
please note the followings:
if you go to define > static load case > dead load self multiplier = 0 (in this case the mass that was calculated based on (from self and specified mass and loads) will not be doubled at all as you assumed,it will be doubled if the previous multiplier...
Dear yasir1989,
in my previous post i showed you how the program calculate total base shear i used SRSS method to show you the procedure in simple way , if you want to use cqc follow the same steps and apply the equation of cqc in my previous excel sheet (which is more complicated)
my...

summation of section cut forces for all frames as shown on the model under response spectrum analysis doesn't equal to total base shear given by etabs..
i tried hard to find a...

don't forget if you find an answer to tell it to me
Best regards..
Dear yasir1989
it seems that you are right (your case happened when using response spectrum analysis , but if you did a static one no such problem will occur,anyway i modified section cuts in your model to get values at each frame , also i apply a static seismic force in x-direction to show my...
Dear yasir1989:
it seems that you use a response spectrum file under the name c/program files(x86)/computer and structures /sap2000 v15/spectra/yasir4.text
which is not uploaded with the Etabs model, anyway i hope you got my idea in my latest post , if not, please upload the response spectrum...
Dear yasir1989
its better to compress your Etabs file (using winrar) before uploading it because i can't download, any way i guess that i understand your problem so please do the followings:
when selecting one frame to get its amount of base shear due to seismic force, select all frame members...
Dear yasir1989,
use section cut method to calculate base shear it is the only method that gives the same values as base shear
steps as follows:
After running the model
from the menu
select > by story level > story 1
from the menu
assign > group names > add new group
from the menu
define >...
