Hello fellow engineers
I would like to ask, when modeling ETABS, how can you tell the program to analyze a building in Steel eccentrically braced?
Because when I run an analysis on the program, ETABS just stated that the building is just special moment frame and not a braced frame
in...
I accidentally erased some of the tools at the tool bar in ETABS (like the pick button of select all,clear, all or select previous) how can I change it back to the default tray?
thank you very much

Hello everyone
I would like to enlighten myself on a certain chapter of ACI 318-08
The ACI 318-08 section 21.5.1.1 stated that the factored axial compressive force on the member, Pu, shall not exceed Agf'c/10
but this part of the code is about flexural members for special moment frames. Can...
Good day everyone,
this topic is a big question for me for so long
its all about the ACI 318-08 Section 21.7.6.2 on how to know if a certain shear wall needs a boundary element
the formula is ok, but I still dont get how some examples I see in the internet is solving the neutral depth "c" in...
Hello everyone
I am designing a certain structure that needs highway design in front of it
i have no experience on design of pavement
I already found a good reference on rigid pavement design
but our client also want to see a calculation for the base course
my question is, how can I design a...
hello fellow eng-tips forumers
I am studying the the Equivalent frame method on the analyis (design) of a two way slab system
on the PCA, (ACI) I found a table on Appendix 20A showing various knf and Cnf
my question is, how did they derived on this kinds of values?
can you give me some...
I have a question on a certain calculation in the
Design of Anchor Reinforcement in Concrete Pedestals by Widianto, Patel and Owen.... I found it in google and I also uploaded this on the link below,
my question is that on page 14 of the article, there's a formula involving the bearing area...
We have an instruction in the office that we must study bridge design
I found a reference done by Modjeski and Masters from AASHTO (and they are using AASHTO code of course)
It called "Comprehensive Design Example for Prestressed Concrete Girder Superstructure Bridge with Commentary"
I just...
hello fellow engineers,
I can manage to transfer the autocad drawings to Microsoft word through .wmf, but i am wondering, is there any program used to transfer it from autocad and word and the and you can edit the autocad by double clicking the window at the word?
or is there any program that...
I'm having a problem on a certain project site because it is swampy
do you have any good reference for Grade beam or tie beam design?
thank you

I want to consider designing a house using a light gauge metal stud framing system
but i want to know its level of fire resistance. I also learned that its walls are made out of wood, how can it stand from floods?
Please give me advice on this kind of framing
thanks

Good day!
i am looking for an ACI 318-71 right now to find if there's a statement there about diaphragms on slabs....But up to know i am still have no luck. When is the time that the ACI included the diaphragm on their book? I am actually looking for the minimum diaphragm thickness of slab and...
Good day,
I am on the retrofitting project, and I resorting in to two methods
1. to use a carbon fiber to reinforced the prestressed slab
2. to use a steel plate with epoxy resins
Its the first time that I encounter these method. Do you have any good references or sample design regarding...
good day to all of you
Just like the title of this thread, i would like to know can STAAD evaluate a long term deflection of a beam?
thank you very much

There's a code on ACI 318-08, 8.9.4 that states that:
8.9.4 — It shall be permitted to analyze solid or ribbed
slabs built integrally with supports, with clear spans
not more than 10 ft, as continuous slabs on knife edge
supports with spans equal to the clear spans of the
slab and width of...
im reading the ACI 530 on special boundary element then i arrive on the computation of largest neutral axis, in the part of 3.3.6.8
the equation needs Cd, or the amplification factor and a deflection ?ne
is ?ne is the deflection determined by elastic analysis as said in ASCE 7-05 eq.12.8-15...

Hello fellow engineers (and non engineers but in the same field)
Rebar detailing can be very complicated and a good construction, estimate and design depends on the right structural plans. Do you have any recommended manual for rebar detailing for starters?
Thank you very much

Please explain to me, what is Dobey Beam?
Ive been searching for this, but im still have no luck
thanks in advance
