    Plate Element Stress - Mx/My vs Global Moment

    Hi! Global moment should have the same answer with the local Mx and My. I think global moment is convenient when the plates are divided triangularly.

    Lateral Nail Capacity

    Hello! Does anyone know where i can find a good source for the lateral capacity of nails on the internet? thanks! Or any internet source where I can compute the capacity myself? Thanks!

    STAAD Partial Moment release

    Thanks for the reply. If we could save a few steel by this analysis, it would really help for future projects. Because if we design for both cases it will be very costly.

    STAAD Partial Moment release

    Hello! How do you determine if the connection between a concrete beam and concrete column is partially released and by how much? In STAAD there is a partial moment release in beam specs where you input a certain value in MPX, MPY and MPZ. What effect would this have on connection details...

    Are Moment Frame, Lateral Bracing or X-bracing; "Structrual"

    civilguy98418, i think you are right... could somebody clarify more on the "lateral gravity load"?

    Hollowcore Slab & CMU Wall

    Can be idealized as equivalent thickness by using stiffness reduction factors <-- please be specific with this. thanx! i saw a post with the equivalent thickness. but the CMU we are using are 10" and 8".. the post only mentioned 6" CMU.. should all walls be assigned pier section then be...

    Hollowcore Slab &amp; CMU Wall

    Im a newbie on etabs.. id like to design a 5storey hotel. the walls will be made from 10" CMU and 8" CMU on the top 3 floors.. The CMU are to carry all vertical loads including the lateral forces.. the slab of the entire bldg is hollowcore concrete planks. any suggestions on wat properties to...

    Cross Bracing for Shear Wall Instead of Plywood

    the simpson diagonal bracing mentioned that... "Not designed to replace structural panel shearwall load-carrying component" anybody who knows alternative for wood shear wall design? what would be the calculation and which code supports it? thanx!

    Rigid or Flexible

    how do i determine if a structure s rigid or flexible? i know as defined, natural frequency of 1Hz sets the boundary.. but, how do i compute for natural frequency? would height over length less than 4 be generally assumed as rigid? would buildings 10 storey or higher be assumed flexible? would...

    Cross Bracing for Shear Wall Instead of Plywood

    Normally, we design thick plywood for shear walls to resist lateral forces. is it practical to use bracing instead? id also like to know more regarding its cost. help much appreciated!

    ASCE-7 '02 External Pressure Coefficient

    Thanks! thats what i did for now.. Interpolate for the upper, interpolate for the lower.. then interpolate again..

    ASCE-7 '02 External Pressure Coefficient

    Im making a program for wind calculation.. In Figure 6-6(con't), in getting the value of Roof Pressure Coefficient Cp, where do you get the value of Cp when Roof Angle is than 10 and h/L is between 0.5 and 1.0? Since the table shows only values of h/L <=0.5 and >=1.0 Help much appreciated!

    X-BRACE DESIGN

    Hello JAE I am wondering how does the endwall windload get transferred to the x-brace. The x-brace is located at a bay that is not adjacent to the endwall but at the next bay. Thank you very much!

    Foundation Pier Design

    We are currently designing a pier foundation for a certain building. We have a Pier End Beam Value of 4000 psf and a skin friction of 1000 psf. The soil report recommends a minimum depth of 8 feet for the piers. But there is water at around 8 feet deep. The soil report did not say it has...

    END COLUMN TO STEEL BEAM CONNECTION

    greetings... I would like to ask for a suggestion in connecting 2nd floor end column of a 2nd floor wooden shearwall to steel beam(wide flange) below.I tried to look for appropriate simpson strap, but i did not see one. I'm thinking of using bolts to be welded to the beams to take care up...

    MODELING SPREAD FOOTING WITH TIE BEAMS

    thanks for the suggestion but what id like to know is how can we model the structure in such a way that the result will show the spread footing design without the moment and the tie beam will be the one to carry the moments. If we have to model it in staad pro having a fixed support the...

    GO BOLTS FOR SHEARWALL

    Greetings... I would like to ask for an idea on the effects of go-bolts in the shearwall and how the tension in the bolts are computed considering a certain bolt spacing. Is this system allowed by the UBC? thank...

    Shear wall with steel

    greeting... I have the same problem also. I am planning to investigate the shear capacity of steel studs with ga. 26 sheating fastened by 1/4&quot; x 14 ga screw at 12&quot; o.c. along the edges. I am planning to do it by investigating the capacity of the most stressed screw and the...

    WOODEN LIGHT FRAME WALLS SYSTEM FOR 4 STOREY BLDG

    thanks uleaum for the very helpfull tips. Actually, we already have a preliminary design of the building. We came out with 2 - 2&quot;x6&quot; Southern Pine No 2 dense studs for the first floor with shrinkage & windload consideration. But one of our problem is the wall layout for the first...
