Engineering a better way.

Preparing your model for QuickQnect

  • All reactions provided by EOR must be in model prior to executing QuickQnect
  • If Shear Reaction force direction is reversed from standard gravity Shear Reaction direction (ie. filler beam web acts upwards on the connection instead of downwards), Shear Reaction force must be entered as a negative value.
  • If sequences affect part marks, sequences must be placed in model prior to connecting.
  • If reactions are based on UDL, beams will be considered composite beams unless identified as non-composite from 1 of 2 methods chosen in the Job Preferences. Option 1 – Identify beam as “NON-COMPOSITE” in Qnect Specific UDA input. Option 2 – Input “Number of Virtual Studs” in the Tekla UDA Field Studs input. Select either method in the Job Preference.
  • Where two or more members come to a joint, model must accurately reflect which members frame to which members. All members (including posts) in stick models must touch steel to be included in the connection detail and calculations.
  • If double angles are shop welded to a galvanized member, it is the detailer’s responsibility to note on shop drawing “All welds to be sealed”.
  • If NYC Integrity, Section BC2213.2.4 is being checked, the largest compressive axial load for a column across all floors the column traverses should be entered in the column’s Tekla UDA End Condition input under compressive force.
  • At beams framing into roof beam (sloped less <= 1/2:12), if filler beam webs are vertical, remember to adjust as required for flange sticking through the roof line.
  • All members in the model to be connected must have these characters in the name identified with these characters, as either BEAM, COLUMN, EMBED, HANGER, POST, VBRACE, HBRACE
  • When connecting column webs, user should take into account erectability of a lower floor beam relative to upper floor. For example, if the upper floor column web has a moment connection, a lower beam may not be able to drop down and needs to be connected with an extended shear plate. Depending on connection preferences, this connection may need to be connected first, before connecting an entire area.
  • Spandrel beams should be identified in the Qnect Specific UDA input.
  • Connections at Embed Plates: All embed plates with shear plate connections must be designed for moment due to eccentric loading of reaction. Please advise EOR. All connections to embed plates with SC bolts need the following note placed on erection drawings, “SC bolts at connections to embed plates must be pre-tensioned after concrete slab is poured”.
  • Moment Connections: Qnect will design a connection as Moment connection if “yes” is chosen to the moment connection question in the Tekla UDA End Condition input, and design moment loads are provided either in the Tekla UDA End Condition input, or a plastic Moment load is defined in the Job Preferences.
    Notes:
    1. Moment loads in the model supersede any defined plastic moments in the Job Preferences.
    2. Moment connections are considered Lateral Moment connections, unless the characters “GRAVITY” are included in the “Name” field of the Tekla UDA End Condition input, ie. GRAVITYBEAM
    3. If “yes” is chosen to the moment connection question in the Tekla UDA End Condition input, but no moment load is provided in the Tekla UDA or as a plastic Moment in the Job Preferences, the connection will not connect.
  • Moment Connections – Lateral: The Moment Load provided in the Tekla UDA End Condition input or Job Preferences plastic moment is considered Maximum Design Moment. If the user provides Gravity Load portions of Moment Load in the Qnect specific UDA input, the Lateral Moment will equal the Maximum Design Moment – Gravity DL portion – Gravity LL portion, and more refined combined Lateral/Gravity Moment load cases will be used for design. If Gravity Load Portions are not included in the Qnect specific UDA input, the Maximum Design Moment will be considered all Lateral Moment.
  • Moment Connections – Gravity: The Moment Load provided in the Tekla UDA End Condition input or Job Preferences plastic moment is considered Maximum Design Moment. If the design is to account for transient unbalanced opposite side loading due to live loads, the Gravity Load LL portion of the Maximum Design Moment must be provided in the Qnect Specific UDA input. In this case, the Gravity DL portion will equal the Maximum Design Moment – Gravity LL in the Qnect Specific UDA portion and more refined combined Dead and Live Gravity Moment load cases will be used for design. If Gravity LL Load Portion is not provided by the user, the Maximum Design Moment provided in the Tekla UDA will be considered all Gravity DL moment.

Selecting an area for connecting

For correct connections, all elements framing into a joint must be chosen together.Partially selected extraction of a floor or area could result in a selection that leaves out members that are important to the engineering and connecting process. Such a selection could lead to incorrectly connected joints.

In order to avoid this result, please be sure to select entire floor(s), entire tier(s) or, even an entire building as required.
