Tools for a Variety of Structural Engineering Tasks
Four Different Roof Configurations
Determine snow loads from drifting in accordance with ASCE 7 for four different roof configurations (Roof Step, Parapet, Adjacent Structure, Roof Projection).
Descriptions in One Location
No flipping through pages to determine which options apply for surface roughness category, exposure of roof, thermal factor, and risk category.
Multiple Drift Cases per Calculation
Set the snow design criteria once, then add as many drift cases as you need for your project.
Seven Connection Types
Design all seven of AISC's standard shear connection types (Double-Angle, Single-Angle, Tee, Single-Plate, Shear End-Plate, Unstiffened Seated, Stiffened Seated) using LRFD or ASD.
Additional Design Options
Choose if the connection is bolted or welded, column or girder supported, top coped, bottom coped, or if it uses workable gages or slotted bolt holes.
Identify Configuration Issues
View the connection drawn to scale. Any issues with the required spacing, edge distances, and clearances will be automatically flagged.
Elastic and Inelastic Methods
Analyze a group of bolts using the elastic or inelastic methods for a load applied at any location in any direction.
Analyze or Design
Determine the bolt group coefficient by entering the bolt and load locations. Include the design load (either factored or unfactored) and the minimum bolt diameter will also be found. Alternatively, provide the bolt diameter and the stresses in the bolts will be calculated instead.
Instantaneous Center of Rotation
Determine the location of the instantaneous center of rotation automatically.
Five Weld Patterns
Choose from five common weld patterns (Single, Double, L-shaped, C-shaped, Box) in all possible orientations.
Elastic and Inelastic Methods
Analyze a weld group using the elastic or inelastic methods for a load applied at any location in any direction.
Automatic Load Combinations
Provide either factored loads or unfactored loads to design the weld. The tool will use the load combinations found in the IBC to combine unfactored loads.

Factored or Unfactored Loads
Choose between providing a single, factored load or multiple, unfactored loads (Dead, Live, etc) which will be combined automatically using the IBC Load Combinations.
Input for Steel Connection
CONNECTION CONFIGURATION :
CONNECTION SIZES :
Click to display the Beam Steel Type input.
(Calculations will assume A992 steel otherwise.)
DESIGN LOAD :
Click to input multiple, unfactored reactions.
(The relevant IBC Load Combinations will be determined automatically.)
Default Materials per Design Manuals
Material types will default to the preferred material specification per the design manuals. You can also change this to another material type or manually set the material strengths.
Input Dimensions Directly on the Drawings
Make adjustments to your design by simply changing the dimensions directly on the drawings and see the effect immediately.
Formulas Written Out and Simplified
Know exactly how the results were determined since calculations show all formulas written out and then with values plugged in.
Output from Steel Connection
WEB COMPACTNESS :
6.97 (29,000 ksi)
(∴ Web is compact, so use Equation 9‑6)
Code References for Calculations
Calculations include references to the IBC or design standards such as ASCE 7 and the Steel Construction Manual.
Easily Find All Variables
Highlight all instances where a variable is used by moving the mouse over one of them.
Output from Snow Load
FLAT ROOF SNOW LOAD, pf :
(Surface Roughness Category: B) (Exposure Of Roof: Sheltered)
Structures intentionally kept below freezing
(Risk Category: III)
