    Bracing for Dual Systems

    and another, ETABS is not part of our curriculum in college. Trainings and seminars for this software did not cover much of it programs and sometimes if the it is not a hands-on you can't absorb it much. I therefore conclude that RESPECT is not varies directly with age or how many years are you...

    Bracing for Dual Systems

    @rowingengineer, thanks for the link....before posting question, I usually search for it in the whole site. But my search yesterday returns to zero so I made a new thread regarding the topic. Sorry if I posted it in a wrong thread, it is because I think that some of us have no time visiting some...

    Bracing for Dual Systems

    ETABS manually calculate base shear based from the Response modification factor that you will be putting for the "define static load case". But of course you know that the base shear is not only based from the R as describe by the ASCE 7-05 table 12.2-1, but also based from the importance...

    Bracing for Dual Systems

    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...

    ETABS Tool/Menu Bar

    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 Poems are made by fools like me, but only God can make a tree. engineers creates wonderful...

    the term Pu in ACI 318-08 21.5

    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...

    determination of "c" of Boundary Element from ACI

    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...

    Construction of 200 ft Cross in Louisiana

    and Sagrada Familia's target completion date is on 2017, so much time spent since 1800s but the real target completion date is in 2026 if I'm not mistaken, the construction became faster due to modern engineering solutions....but according to wikipedia, there's a problem regarding the stability...

    Construction of 200 ft Cross in Louisiana

    you can see a lot of structural innovation on Churches alone like the use of flying buttresses in Church Reim Using the Divine Proportion for Chartres Cathedral (also have a great blue stained glass) And how Filippo Brunelleschi uses a kind of arrangement that made that Dome in France Poems...

    Earthquake Engineering

    if you love bread and amazed on how those things puff like that, then be a baker. I can say that if you are really interested on that field then go with It.... But experience is the best teacher, I suggest you must find a firm who do specialized on that field (they are mostly big and...

    Base Course for Highway Pavement

    thanks guys for the advice I am doing an assumed thickness for the design details. I believe our senior engineer who specialized in this field will check on it But of course if you are assuming, it must be nearer to reality I used the graph of Elwyn Seelye book on the pavement thickness...

    Equivalent Frame Method on slab

    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...
