The Strong Frame moment frame selector software is a free software package that can be downloaded at strongtie.com/strongframe and used to select a moment frame meeting the Designer’s specific design and project requirements. The tool allows for entering and adjusting the various inputs based on a project’s design needs. Design beam and column using selected Simpson Strong-Tie standard elements. See Strong Frame Special Moment Frame: Standard Sizes for more information. Currently, the Strong Frame selector software can provide solutions for OMF 1-story x 1-bay; 2-story x 1-bay; and special moment frame 1-story x 1-bay.
Along with giving you enhanced design possibilities, Simpson Strong-Tie saves Designers time by providing design services for built-to-order multi-story and multi-bay frames. Designers receive a complete package from Simpson Strong-Tie that includes drawings and calculations that are submittal-ready. Simpson Strong-Tie even provides post-submission support with the plan check process.
Designer submits the loading worksheet or Strong Frame Selector input file to Simpson Strong-Tie at firstname.lastname@example.org.
Simpson Strong-Tie confirms receipt of the worksheet within 24 hours. Using state-of-the-art software, we create a design based on our patented Yield-Link® structural fuse technology to meet all your design requirements — usually within 48 hours.
Designer receives a submittal-ready design package and drawings in electronic format from Simpson Strong-Tie.
Simpson Strong-Tie assists the Designer with any post-submittal Strong Frame questions.
Simpson Strong-Tie provides no-equal jobsite field support.
Visit strongtie.com/strongframe for moment frame tables with incremental frame heights and widths based on assumed design criteria. Once a width and height are assumed, a frame model number can be selected depending on the required lateral load for the system. These tables are available for both OMF and SMF in a single-bay, single-level configuration. Note the design assumptions at the bottom of each load table.
The design requirements for calculating the beam-to-column moment connection can be found in ICC-ES ESR-2802 or in AISC 358-16, Chapter 12.
When providing the loading sheets or the input form within the Strong Frame moment frame selector software, the user needs to provide the necessary lateral load and gravity load as well as the frame height and width.
The following are helpful guidelines when providing design criteria:
Whichever method you use for specifying a Strong Frame moment frame, it is important to provide a complete model number and/or frame elevation drawing in the design construction documents. Model numbers are typically listed for one-story, two-story or two-bay frames. For other configurations, an elevation drawing will be necessary. It is also important to provide a model for the anchorage required at each individual column base. Anchorage models are not tied to a frame model and shall be specified by the Designer. Strong Frame moment frame selector software or Simpson Strong-Tie design services will help provide an anchorage solution based on the frame base reactions, supplied foundation design criteria and ACI 318 anchorage calculations.
A typical Strong Frame moment frame is delivered to the jobsite with main structural components installed (welded plates and shear tabs, Yield-Link® fuse-to-beam connections), wood nailers preinstalled, holes predrilled for utilities, grey primer coating and identification/instruction sticker labels. Beams and columns are bundled together and can be easily field bolted and set on the installed moment frame anchorage kits. However, certain instances occur where the typical components need to be adjusted to meet specific jobsite or design requirements. For a frame installed in a CFS or structural steel building, wood nailers may not be necessary and can be omitted. Where a ledger of infill is required in the web of the beam or column, additional predrilled web holes can be specified based on the Designer’s specification. Or where the columns may be left visible in the structure, the nailers, primer, holes and stickers may need to be omitted so that the finishes can be applied at the site. Hot-dip galvanization may also available where the steel might be exposed to weather. See Strong Frame Ordering Process and Options for additional options and considerations.
