Models may be imported from ETABS into SAFE by specifying a global-Z elevation. All objects

connected to joints located witin a tolerance of tis elevation import into SAFE. !oad data incl"des

e#"ivalent joint forces wic acco"nt for loading from tose str"ct"ral systems wic are not

imported. !inear-static and response-spectr"m load cases$ and teir associated data$ also import.

• %ow are wall systems imported from ETABS into SAFE&

• %ow do ' s"ccessf"lly e(port floors from ETABS to SAFE&

• %ow is only some information imported into an e(isting SAFE model&

%ow are wall systems imported from ETABS into SAFE&

Answer: Adjoining walls a"tomatically import into SAFE$ to"g walls below te floor slab import as

wall objects$ wereas walls above import as deep beams. Tis prod"ces te proper beavior.

%ow do ' s"ccessf"lly e(port floors from ETABS to SAFE&

Extended Question: After "sing te E(port Floor !oads and !oads from Above option$ te slab

moments from seismic loading calc"lated witin SAFE are different from tose in ETABS. Also$ it

seems tat seismic forces are not applied at te floor level. )at is te proper proced"re for e(port&

Answer: )en floor systems are s"bjected to lateral loads$ we recommend "sing te Floor !oads

and )all and *ol"mn +istortions option to e(port from ETABS to SAFE. Forces may also beman"ally applied after te model transfers.

%ow is only some information imported into an e(isting SAFE model&

Extended Question: ' ave imported an ETABS model into SAFE$ b"t now ' ave "pdated loading

witin te ETABS model$ and ' wo"ld li,e to import only tese loads into te SAFE model wito"t

overwriting any oter information object properties$ load combinations$ etc.. %ow is tis done&

Answer: Two options are available for importing only a specific set of information into an

e(istingSAFE model$ incl"ding/

• Option 1.

0. 'mport te "pdated ETABS 1.f2, floor as a new SAFE model.

2. )itin te initial SAFE model$ tro"g File 3 'mport 3 F2,$ select te 1.4sf file of tis

newly created SAFE model.

5. Select 'mport as a 6ew Model or Add to E(isting Model$ ten specify wic objects$

loads$ etc. will be replaced or ,ept in te event tat tey occ"r in te same location.

• Option 2.

0. 'mport te "pdated ETABS 1.f2, floor as a new SAFE model.

2. Select Edit 3 'terative +atabase Editing to copy te "pdated tables into te initial

Steps

ETABS to SAFE/

0. )en e(porting from ETABS for mat design as opposed to elevated slab$ "se tee(port floor loads and loads from above option wit te BASE Story to e(port selected.

6otes/Model m"st be analy7ed and loc,ed to e(port.

Te e(port floor loads only option is for individ"al floor plate design.

Te e(port floor loads pl"s *ol"mn and )all +istortions is necessary only wendisplacement compatibility co"ld govern and needs to be cec,ed floor slab design.Effects p"ncing sear and fle("ral reinforcement design

2. 'mport .f2, file to SAFE

5. Assign Soil S"pports to 8aft Slab

6otes/8ecommend not drawing slab at BASE level in ETABS$ b"t draw in SAFE after col"mnsand walls ave already been imported from .f2, file.

 As te soil engineer recommends different stiffness val"es$ different mats will need tobe drawn wit appropriate soil s"pport. Soil press"re is commonly different "nderdifferent portions of te str"ct"re. Te soil s"pport val"e is additive- mat properties inSAFE cannot overlap.

Better to ,eep tis level of modelling to SAFE rater tan adding to r"n time of ETABSmodels.

 Also$ SAFE and ETABS c"rrently mes differently. ETABS is more tedio"s wit non-ortogonal grid conditions as sell elements m"st be man"ally mesed to col"mns.SAFE will a"tomatically to col"mns.

9. Assign fo"ndation area loads.

:. Assign appropriate design code. Most c"rrent A*' option
