• Seismic Parameters - Zip Code Not Found

    Hello, I was curious if anyone has encountered this error. I'm working on a steel structure to support pipes and electrical cable trays. The structure is located in a suburb of Phoenix, AZ (Eloy). The zip code is 85131. What I discovered was when…

  • RAM Frame - Joint Check for HSS Brace in OCBF

    Hello, In RAM Frame when running the joint check for Seismic Provisions, I get these errors associated with the joints of my OCBF frames with HSS braces, HSS columns, and wide flange beams. Is this just saying that RAM won't do a code check for these…

  • Required Strength for EBF Column

    I am designing 3-story Eccentric Brace Frames using the Seismic Provisions in RAM Frame and I am confused with the required strength value that is being determined for the axial design of the 1st story column. The Member Code Check report for the column…

  • RAM Connection Seismic Provisions

    When checking the Seismic Provisions option in a CBB Connection the demand in the results output is 0 for all brace-gusset, gusset-beam, and gusset-column interface limit state checks. Is there a patch or expected fix for this?

  • RE: ACI 318-08 Ordinary Moment Frame Seismic Provisions

    I logged an enhancement to perform this check just last month, Re: Enhancement 696671: Check ACI 318-08 (& 318-11) Section 21.2.3 for OMF columns that are short (re 21.3.3) It has not been implemented yet. You would have to make the columns lateral…

  • RE: RAM Frame Seismic Provisions - Required Strength Failure SCBF Column

    I just ran your file, "SCBF Model with seismic error.rss", using the latest version 15.04. The warnings I get for most of the lower level frame columns are: This is triggered by having some of the adjacent framing not assigned any frame type. If all…

  • RE: BCF-Shear force at column face - Seismic provision

    I confirmed that in our section database in Ram Connection the UB406x178x67 is listed with Ze = 1,350,000 mm^3. At some point out data must have been rounded or reduced in precision. It is possible to export the shape data to a spreadsheet, then generate…

  • RE: ACI 21.6.1 Requirements being applied to Gravity Columns?

    I assume we are talking about ACI 318-08 (or 11) here. The governing section of the code is 21.13, 'Members not designed as part of the seismic-force resisting system'. This section is applied to gravity columns when the SDC is D, E or F (note this is…

  • RE: Concrete shearwall design & ACI 318-11 section 21.9.2.1

    Please take a look at the program manual, RamConcreteShearWall.pdf, Section 7.4 Reinforcement Ratio Limits for some details on how we check ACI 318-11 Section 21.9.2.1. If that does not answer your question, let me know. I've copied a part of that below…

  • RE: Does RAM Concrete check for ACI 21.13: Members not designated as part of the SFR system

    See Section 4.8.4 in the RAM Concrete Column Manual for the sections of 21.13 that are implemented in the program. Induced moments and shears are not calculated by the program, so the program follows ACI 318-11 21.13.4 and not 21.13.2 or 21.13.3 when…
