Vulcraft’s online design tools make it easier for you to specify our products, helping you increase project performance and reduce project costs. Our online tools will help you select the most cost-effective products for your project, including joists, roof deck, floor deck, composite deck, and dovetail deck. Please limit usage to 6 design tools at a given time for maximum performance.

Our Joist Design Tools can help you find the most economical joist depths, perform shear and moment comparisons, analyze vibration, and much more.

DYNAMIC JOIST WIZARD

Select the most economic joist depth based on your inputted special loads including uniform and non-uniform distributed, concentrated, axial, and end moments. Outputs include joist self-weight, top chord width, seat depth, and allowable maximum duct size.

JOIST ANALYSIS AID

Our Joist Analysis Aid will evaluate your joist for combined uniform and concentrated loading, and will suggest where webs will see a stress reversal and a designation and bridging.

SHEAR AND MOMENT COMPARISON

This tool compares the shear and moment diagram for two different loading conditions.

VIBRATION ANALYSIS – WALKING

This tool analyzes floor system for Vibration based on Walking criteria using SJI TD5 and AISC DG11, and is for Joist floor with several Girder options.

KNIFE PLATE CONNECTION DESIGN

This tool will check knife plates for both Top Chord and Bottom Chord Axial Load Transfer.

TIE-PLATE CONNECTION DESIGN

When you need to design your Axial-Load Transfer between bays with either an Under-Chord or On-Top Tie-Plate detail, this tool will provide calculations and any needed info to specify connection.

COMPOSITE JOIST FLOOR SYSTEM AID

If you need to analyze a Composite Joists System for your Floor, this tool provides specification guidance, estimated dead loads, stud quantities, bridging, and maximum sizes for ductwork.

If you need to calculate loads, or analyze deck diaphragm shear and stiffness, and more, our Roof Deck Design Tools can help you find the answers you need.

BARE DECK DIAPHRAGM

Formerly 2018 IBC Deck Diaphragm

Calculate the bare deck diaphragm shear and stiffness for your configuration based on AISI S310 and IAPMO reports.

BARE DECK UNIFORM LOAD

Formerly Steel Deck Uniform Load

Determine the uniform gravity and wind-uplift loads for your bare deck configurations.

BARE DECK CONCENTRATED LOAD

Formerly Steel Deck Roving Load

Calculate the concentrated roving load that may be applied to any rib of the selected roof deck, in addition to the defined uniform loads.

BARE DECK WEB CRIPPLING

Formerly Web Crippling Loads

Calculate one flange and two flange web crippling loads based on bearing length.

Calculate unshored construction spans, deck-slab diaphragm strengths and stiffness, spanning pour stops, and more with our Floor Deck Design Tools.

COMPOSITE DECK-SLAB SUPERIMPOSED LOAD

Formerly Composite Deck-Slab Strength

Calculate composite deck-slab strength and maximum unshored span tables for your composite deck configurations.

UNSHORED CONSTRUCTION SPAN

Formerly Unshored Span Calculator

Calculate maximum unshored construction spans for thick slabs based on your design criteria.

DECK-SLAB DIAPHRAGM STRENGTH

Calculate your deck-slab diaphragm strength and stiffness for selected deck profiles based on AISI S310-16.

BARE DECK DIAPHRAGM

Formerly 2018 IBC Deck Diaphragm

Calculate the bare deck diaphragm shear and stiffness for your configuration based on AISI S310 and IAPMO reports.

BARE DECK UNIFORM LOAD

Formerly Steel Deck Uniform Load

Determine the uniform gravity and wind-uplift loads for your bare deck configurations.

If you need help deciding which grating will work best for your project, our Bar Grating Design Tool will help you find the solution.

Bar Grating Design Aid

Need help deciding what grating to use? This tool will help you specify exactly what you need for your specific situation for a grating surface or stair treads.

Our BIM Tools are perfect for specifying and modeling a variety of joists and joist girders to aid in the quoting and detailing process.

BIM Technology Overview

Building Information Model (BIM) encompasses building geometry, spatial relationships, geographic information, quantities and properties of building components.

NUBIM® FOR REVIT® DOWNLOADS

Our NuBIM® for Revit® add-in allows users to specify and model all parallel chord joists and joist girders available from Vulcraft as well as a number of common special profile joists and composite joists. Learn More About the Add-In for Revit®

NUBIM® FOR TEKLA® DOWNLOADS

Vulcraft’s Joist Plug-In for Tekla® Structures enables you to specify Vulcraft joists during the creation of the building model. The model can be exported containing Vulcraft joist information, which can then be used by Vulcraft to aid in the quoting and detailing process. Learn More About the Plug-In for Tekla®
