The programs in this section provide analysis and design for structural elements made of wood.

Program modules for WOOD design are designed to be in conformance with ANSI / AF & PA  National Design Specification  (NDS) dated 30 November 2001. All analysis and design is done using allowable stress design.

 

 

Timber Beam & Joist Design

Lets you quickly design single span members with cantilevers. Designed specifically for simple roof/ceiling/floor framing, up to 8 beams can be designed per calc sheet. Full stress and deflection analysis & design is provided.

 

Multi-Span Timber Beam

Multi-Span Timber Beam allows design of up to eight spans on one calculation sheet. Two modes are available; each span can be considered as simply supported with optional cantilevers or all can be continuous with cantilevers and varying end fixities. Dead and live point, moment, and uniform/trapezoidal loads can be applied in any combination. Alternate span live loading is easily defined. Full AITC stress checks are performed (including long beams), and reactions, shears , moments, deflections, and stresses are given.

 

General Timber Beam

Heavy Timber Beam allows users very detailed design ability, offering up to 23 dead and live point, moment, and uniform/trapezoidal loads. Fixed, pinned, and free end restraints and cantilevers are available. All possible dead and live loading's are considered for calculation of maximum shears, moments, deflections, and combined stresses. Full AITC stress analysis is performed considering shear/depth reductions and duration of load factors.

 

Series of Cantilevered Beams

Series of Cantilevered Beams is perfect for design of simple span & cantilevered roof and floor systems typically used in warehouse type structures. The need to optimize cantilever lengths and evaluate deflections and cambers for these systems is completely provided. The program places live loads at different locations to determine maximum reactions, shears, moments, and dead and live load deflections. Cantilever bracing, load duration, and laminations are considered when performing stress checks.

 

Timber Column Design

Timber Column Design analyzes rectangular and circular timber columns subjected to axial loads, eccentricities, haunch loads, and lateral moments. Allowable bending and axial stress are calculated considering unbraced lengths and interaction formulas.

 

Plywood Shear Wall & Footing

Plywood Shear Wall Footing greatly simplifies designing typical plywood shear walls. By using diaphragm shears, drag forces, and vertical stabilizing loads, a complete wall and footing design will be given. Nailing, wall stability, and footing designs are provided.

 

Plywood Diaphragm Design

Plywood Diaphragm Design provides fast design of rectangular plywood diaphragms, and follows '94 UBC table 25-J-1 for blocked and unblocked diaphragms. The program can be used for either wind or seismic conditions. Boundary loads and diaphragm weight are used to calculate chord forces and boundary shears, while internal tables generate nailing schedules.

 

High-Load Plywood Diaphragm

Plywood Diaphragm Design provides fast design of rectangular plywood diaphragms, and follows ICBO Report #1952 for 23/32"; plywood diaphragms. The program can be used for either wind or seismic conditions. Boundary loads and diaphragm weight are used to calculate chord forces and boundary shears, while internal tables generate nailing schedules.

 

Wood Ledger Design

Wood Ledger Design combines vertical and lateral loads applied to ledgers to calculate maximum shears & moments. Flexible bolting is allowed with maximum loads compared to Hankinson formula allowable's. Perfect for ledgers supporting roof or floor diaphragms.

 

Bolt Groups in Timber Members

Bolt Groups in Timber Members provides an analysis of steel bolts and side plates transmitting axial loads. Considers reductions for bolt spacing, quantity, plate size, force direction, and more.
