VULCRAFT JOIST DESIGN TOOLS

Knife Plate Connection Design

Check knife plates for both Top Chord and Bottom Chord Axial Load Transfer.

Tie-Plate Connection Design

Design your Axial-Load Transfer between bays with either an Under-Chord or On-Top Tie-Plate detail. Tool provides calculations as well as needed info to specify connection.

Joist Depth Selection Aid

Curious what depth(s) are most economical for your open-web steel joist system? Using over 13,000 actual designs, this tool will help you compare your options.

Shear and Moment Comparison

Compares the shear and moment diagram for two different loading conditions.

Composite Joist Floor System Aid

Analyze a Composite Joists System for your Floor. Tool provides specification guidance, estimated dead loads, stud quantities, bridging, and maximum sizes for ductwork.

Vibration Analysis – Walking

Analyze floor system for Vibration based on Walking criteria using SJI TD5 and AISC DG11. Tool is for Joist floor with several Girder options.


Joist Analysis Aid

Analyze your joist for combined uniform and concentrated loading. Tool will suggest where webs will see a stress reversal and a designation and bridging.

NEW! Ecospan® Floor System Estimating Aid

Interested in how Ecospan® compares to other floor systems? This tool will help you determine depths, joist designations, joist/deck dead loads, fastener patterns, flush-plate connection checks, maximum ductwork, and much more.

VULCRAFT ROOF DECK DESIGN TOOLS

2018 IBC Deck Diaphragm

Calculate your unfilled deck diaphragm shear and stiffness for your exact condition based on the American Iron and Steel Institute AISI S310-16.

Steel Deck Uniform Load

Determine the uniform gravity and wind-uplift load for steel deck based on strength, deflection, and attachment to supporting members.


NEW! Steel Deck Wall Anchorage Design

Design steel deck to resist the wall anchorage forces from combined seismic, wind, and gravity loading based on the combined axial and bending strength.

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.

2015 IBC Deck Diaphragm

Calculate your unfilled deck diaphragm shear and stiffness for your exact condition based on the "Steel Deck Institute Diaphragm Design Manual, Third Edition" (DDM03).

Web Crippling Loads

Calculate one flange and two flange web crippling loads based on AISI S100-16 with different end and interior bearing lengths.


VULCRAFT FLOOR DECK DESIGN TOOLS

Unshored Span Calculator

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

NEW! High Performance Deck-Slab Diaphragm Strength

Calculate diaphragm strengths and stiffness for deck-slabs with plain concrete, Bekaert Dramix steel fibers, WWR or rebar.

Deck-Slab Diaphragm Strength

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

Composite Deck-Slab Strength

Create your custom composite deck-slab strength and maximum unshored span tables for selected composite deck profiles.

Pour Stop as Beam

Select a Pour Stop to use as a beam spanning between deck supports per Steel Deck Institute Technical Note No. 3

 

STEEL BAR GRATING DESIGN TOOLS

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.

 

BIM TOOLS

NUBIM® FOR REVIT

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, Ecospan and composite joists.
