    Design of brace in xy plane

    and depending on your assumption for the function of your braces. offset it to the floor so it will not carry floor loadings. cprr0107

    Design of brace in xy plane

    Try to model it as a tension member element only. I have modeled one of those. But, one problem is that these braces still carry compression though i have modeled it as a tension element only-(compression limit=0). you may see also my post above. cprr0107

    T/C Limit("Compression limit=0" still carry compression)

    I have modeled a interconnected steel towers with vertical and horizontal x-bracings. I have defined these x-bracings with a compression limit=0 using the "T/C limit" feature by SAP2000 My design analysis shows that these vertical and horizontal oriented braces were "still" designed for...

    How to model TENSION only X braces in ETABS 9.7 ?

    I work on SAP2000. basically the definition of features are almost the same with ETABS. try the link: http://www.csiberkeley.com/Support_WL_SAP.html and download the tutorial file : "Tension-Only Bracing" cprr0107

    check&design of nonprismatic concrete column in sap2000

    Dear all, Can SAP2000 perform check and design of nonprismatic concrete columns? i have performed it for steel columns but i just cannot perform the modeling correctly for concrete columns. thanks in advance!! cprr0107

    difference on analysis occured in V14 and V8

    V14 vs. V8 1.) I modeled a simple howe truss in SAP V.14 and compared it with SAP V.8. i only have released the moments(M2&M3) for the diagonal and vertical members of the truss, having my top and bottom cord with no moment releases. SAP v. 8 analysis results does not show any WARNINGS. but...

    How does SAP2000 calculates (I/L) in nonprismatic columns

    Thanks for all your replies. I already know what to look at and how does SAP does it(buckling theory). thanks again.. cprr0107

    How does SAP2000 calculates (I/L) in nonprismatic columns

    -IJR thank you for your reply. i use v14. I need to verify how does Sap2000 approach for these value for nonprismatic steel columns. i have modeled a moment frame and my model shows value of k=2.703(major) and k=1.150(minor). I have already verified the output of sap 2000 for prismatic...

    How does SAP2000 calculates (I/L) in nonprismatic columns

    How does SAP2000 calculates (I/L) in nonprismatic columns for the calculation of the effective length k factors. You may see Chap. 2 p.13 design algorithms of SAP2000. thanks..!!

    Does SAP 2000 analyze and design warping?

    Does SAP 2000 analyze and design warping? How can I display output considering warping in steel sections? please help.. thanks in advance!!

    Structural Systems

    Good day! I am modeling a 4.4mx4.4m steel braced frame tower like structure, 25m high, with operable machine floor at top. I have modeled The columns and horizontal members(beams) to be fixed at the joints(no releases). And with hinge supports. SAP2000 automatically assign effective length...
