Eng.Heba Adel – Structural Engineer-Alexandria university
Then from upper bar press on run analysis ….press on save and wait till
design stage finish…then go to post processing mode ….done…. as following
snaps:

Then load cases will appear ….press on apply…..ok ….as following snaps:
then we can see model result such as deflection shape , moments , and
forces as following snaps:

Eng.Heba Adel – Structural Engineer-Alexandria university
Regarding results scale: from upper bar….scale…..change scale of bending Y
and bending Z to be =300 or any suitable value to make scale of moment
clear …then apply… as following snaps:

3-design portal frame: from upper bar….utilities….command file….from left list
…double click on perform analysis….from right commands insert new row below “
perform analysis” then write list ….then double click on load list and write from 7
to 16 (this refer to load combinations that the design will be performed by
it)….then press on save as following snaps:
11 | P a g e
Eng.Heba Adel – Structural Engineer-Alexandria university
From upper bar….design….then from right bar choose code of design to be
(AISC-LRFD)….then press on define parameters such as Fy , UNB , UNT(un
braced length for rafters and columns (top and bottom flange)) as following
snaps:

Then start to assign Fy of each materials : from upper
bar…..select….attributes….property name…..tension only beams…..then
press on inverse to choose steel members as following snaps:
16 | P a g e
Eng.Heba Adel – Structural Engineer-Alexandria university
Then select Fy =345000 kn/m2 ….assign to selected beams as following
snaps:
Repeat the previous steps to assign tension members Fy as following
snaps:

Then assign UNB&UNT : from upper bar ….select….attributes….property
name…..by property…..select all tapered sections….right click ….new
view…from upper bar….view….select view of elevation then select rafters
….choose from right bar UNB1.4 and choose assign to selected beams and
in the same way assign UNT1.4 as following snaps:

From view of elevation….select columns to assign with UNB2.2&UNT2.2 as
following snaps:
21 | P a g e
Eng.Heba Adel – Structural Engineer-Alexandria university
From right bar….commands….check code…add….takeoff…add then
close….then press on check code in right bar….from view ….display whole
structure…then assign to view…and do the same steps with steel takeoff as
following snaps:
22 | P a g e
Eng.Heba Adel – Structural Engineer-Alexandria university
From upper bar…analysis and design….run analysis…save….done…then
from left bar …postprocessing….ok….beam results….utilization ratio..
23 | P a g e
Eng.Heba Adel – Structural Engineer-Alexandria university
we will find that bracing members and tubes were not designed ….so from
left bar …analytical model….properties….

After defining sections from data base for bracing members and strut….we
need to assign with new sections ….from upper bar
….select….attributes….property name….by property….select bracing
members(CIR 0.98)….then from right bar hoose RD25…..assign to selected
beams…assign as following snaps:
Repeat the previous step to assign strut members with new section we
defined from data base as following snaps:
26 | P a g e
Eng.Heba Adel – Structural Engineer-Alexandria university
Then delete old sections of bracing and strut members:
27 | P a g e
Eng.Heba Adel – Structural Engineer-Alexandria university
Then go to analysis and design againmake sure that design parameters still
as we defined before then run analysis….then choose
postprocessing….beam results….utilization ratio…then we will find bracing
and struts were designed and fail as following snaps:
To view utilization ratio for one frame in elevation…..from upper
bar….view….plan view…select one frame in plan….right click …new
view…then from view choose elevation view…..

then go to results again ….from upper bar….from layouts we can display
results of nodes , beams ,plates as following snaps:
30 | P a g e

Eng.Heba Adel – Structural Engineer-Alexandria university
Then from upper bar….annotate ….beam results….bending….check on ends
, maximum and midpoint as following snaps:

Eng.Heba Adel – Structural Engineer-Alexandria university
Base reactions: from left bar ….analytical model….from view….display
whole structure….then choose elevation view….then select all nodes of
base from node cursor ….right click….new view…choose plan view so that
we can see nodes only….from upper bar….analysis and design….run
analysis…postprocessing …….results….annotate…reactions….Gx, Gy
,Gz….annotate

We can see base reactions for any load combinations :
From upper bar….utilities….take picture….rename it to reactions as
following snap:
37 | P a g e
Eng.Heba Adel – Structural Engineer-Alexandria university
From results….annotate…reactions Gx,Gy,Gz….remove all….then go to
analytical model…from view….nodes label…from utilities…take
picture…rename it to be reactions nodes….as following snaps:

Then go to postprocessing…..report….setup report….select from inputs
what you want to show in report and also outputs as following snaps:
