Structural Design and Engineering Software

Software for designing light-frame or heavy timber structures in terms of sizing structural members such as beams, joists, trusses, studs, and various types of columns. Included are calculators for beam deflection, maximum beam spans, column loading, wooden shear walls, connectors, drag forces, and more.

BeamChek
Wood and steel structural design software that performs a variety of calculations for beams, joists, and rafters. The built-in database includes steel, wood, timber, glu-lams, and structural composite lumber. AC Software, Inc.  Windows.

Beam Deflection
Calculates beam stress and deflections. Input parameters include how ends of beam are supported ( pinned, clamped or free), intermediate support characteristics, and elasticity and cross section of the beam. Echoscan.  DOS.

Beam deflection
Online calculators for computing structural beam bending with a variety of beam support and loading situations. Formulas included. From Engineers Edge.

Beam View
Online utility for studying shear, moment, and deflection distribution over the length of a beam which is under various transverse loads  Can select from four types of beams:1. Cantilever, 2. Both ends pinned  (Simply supported beam), 3. Both ends clamped, 4. One end pinned and the other end clamped.

Bova-nail Truss
Offers complete project management and processing including individual phases of structure design, from price quotation to manufacturing, documentation and outputs for computer-controlled machinery.

GT STRUDL
Structural analysis and design software with a variety of applications including designing timber frame structures.  Georgia Tech Research Corporation.  Windows.

Loads Calculator
Roof loads, snow loads, floor loads, wind, and seismic loading, this program calculates them all. Stop wasting time searching reference and code books.  Dot XLS.  Excel spreadsheet.

Max Span Calculator
Calculates maximum safe horizontal span for joists and rafters given species, lumber dimensions, grade, deflection limit, spacing, live load, and dead load. Online utility.

Moisture Content Adjustment Program
Computes strength properties of dimension lumber at varying moisture contents. US Forest Products Lab.  Fortran code.

Roarks' Formulas for Stress and Strain 
Online utilities derived from the classic Roark's engineering handbook. If you're into structural analysis involving beams and columns, this is great stuff. (A free registration is required to use the utilities).

Roof Framing Calculator
Allows you to design and print hip and gable roof layout plans. Options include wall length, wall width, roof angle, rafter thickness, rafter depth, spacing, and overhang. Blocklayer.com.  Online utility.

SpanCalc
