    STRUCTURAL DESIGN
  1. Inclined force

    thanks ,i just came to know that we can assign inclined force (point load) to member by rotating its joint local axis but in sap not in etabs.
  2. Inclined force

    Can we assign force/point load with some angle to any member(shell or line element)?
  3. SAGRODS AND SAP2000

    you can even use etabs for this.
  4. Vu* in concrete frame design

    DEAR Rana bahi said rightly,this Vu* is for beam(frame action) ,this is magnified shear demand only applicable in sway intermediate and sway special,this i found in ''2012 IBC SEAOC STRUCTURAL DESIGN MANUAL" VOLUME 3. BUT you will not find this in ACI 318-14 AND ALSO DO NOT EXIST IN ETABS MANUAL(CONCRETE FRAME DESIGN ). THIS IS HOW IT IS CALCULATED, vu*=ῳV x vu and ῳV=0.9+n/10 AND ‘’n’’ IS NUMBER OF STORIES ῳV =SHEAR AMPLIFICATION FACTOR
  5. HOW Vu* calculated in Etabs,this is the output of etabs SHEAR DETAILS. Factored Vu2 kip Factored Mu3 kip-ft Factored Vu* kip Factored Mu* kip-ft Capacity Vp kip Gravity Vg kip 68.185 -291.4801 105.165 -474.5679 92.675 31.213
  6. 2nd order analysis

    i think this kind of broad topic should be consulted to books better.
  7. ECCENTRIC LOAD IN ETABS

    Bcz everyone in structure is right if he/she is using rational approach,no matter what different technique we are using,thanks
  8. ECCENTRIC LOAD IN ETABS

    column will not take axial load in etabs,if you are applying at 0.75 inch from centriod of column
  9. ECCENTRIC LOAD IN ETABS

    load will not be transfered to node in second option.
  10. sorry i was not having idea of this i mean even document sharing .
  11. aoa,can someone provide me NBCC IN PDF.
  12. Tapered column footing design

    just design with width 5ft,this is not big issue.
  13. Multilevel Raft Foundation

    1) More interaction between the geotechnical and structural engineer after the structural engineer has reviewed the geotechnical report and started design work. During this conversation, the structural engineer should: Talk through their understanding of the geotechnical recommendations. Explain what has been done or will be done concerning site grading, basements, building location, and footing bearing elevations. Provide the magnitude of the loads on the footings. Break out the live loads between persistent and transient loads so that transient live loads do not drive the design. Explain the range of footing sizes that will be used with the allowable bearing pressure provided in the geotechnical report. For combined footings or a mat that uses a subgrade modulus, give the geotechnical engineer the elevation and size of the mat/footing, and ask if the subgrade modulus is applicable or needs to be modified. Request that the geotechnical engineer checks their recommended bearing pressures to see if the bearing pressure can be increased now that they have actual loads and know what soils the footings will bear on.The fact that the geotechnical engineer develops their understanding of the soils by sampling only about 0.000015% of the soil under the site,,THANKS
