TIMBER Structural Analysis and Design software





Part of the GSE (General Structural Engineering) software, GSE TIMBER allows to design and analyze timber structures such as light wood framing as well as engineered wood structures according to the  2018 National Design Specification (NDS) for Wood Construction and the CAN/CSA O86-14 revision 2017 standards. GSE WOOD allows to combine these two types of structures (beam-column frame and light framing). The Light Framing package extends the Mass Timber features. GSE Light Framing system is a high-level technology for automated parametric generation, analysis and design of bearing walls and shearwalls.

Mass timber design
• All parameters required to calculate the resistance of the elements such as unbraced length, buckling lengths, buckling factors, resistance factors and others can be customized either graphically or from spreadsheets.
• The program can also calculate several design parameters.
• Design made according to CSA O86-14 (r2017) and NDS-2018.
• Calculations of bending, compression, tension, shear, bearing and combined resistance of wood elements can be carried on the results of a linear, P-Delta, non-linear, seismic or dynamic analysis.
• Complete check of deflection according to a comprehensive set of criterions.
• Limit states (unity checks) can be displayed graphically on the 3D model by means of colors or numerically in spreadsheets and reports.
• All intermediate results required to verify the calculations are provided in spreadsheets.
• Notches can be defined at the top and bottom chord for each member end for the purpose of calculating the shear resistance.
• The Re-Design command allows to run a partial analysis on selected members. It is possible to modify the section of the members or the material type and properties. The chosen section may then be assigned to the selected members of the model.
• Calculation of structural elements like beams, simple or built-up columns, inclined roof purlins, straps, decking, various arcs (circular, parabolic, Tudor, triangular, broken arcs).
• Beams and arcs may be straight or curved with a constant or variable section. For curved elements, tension perpendicular to grain needs to be verified manually.
• Calculates the ultimate limit states, service limit states and vibration control of wood joists based on the CCMC 1997 report.
• Roofs and floors made of plywood or OSB panels can be calculated.
• Calculation of wood trusses with metallic connections according to the TPIC.
Vibration of sawn lumber joists
The vibration limit state is calculated for sawn lumber floor joists. To improve the productivity of GSE users, the floor joists are automatically generated inside the truss load surfaces.

Using the automatically generated joists, the resistance and vibration limit states are calculated for each floor. The resistance of sawn lumber joists are verified for the CSA O86 and National Design Specification (NDS) standards. For the vibration limit state, the maximum allowable span is calculated using the NBCC provisions.
Sections and grades
• Rectangular sawn lumbers.
• Composite sections such as Laminated Veneer Lumber (LVL), Parallel Strand umber (PSL), Laminated Strand Lumber (LSL).
• Glued-Laminates sections.
• Built-up sections (multiple vertical or horizontal plies of sawn lumbers or composite lumbers) with different anchorage mechanisms.
• Open-web, engineering joists and wood panels.
• Extensive library of common sawn wood sizes available on the market.
• Extensive library of proprietary wood joists, wood panels, composite sections and glulam sections.
• Sections of special dimensions (6 1/4 x 11 3/8 for example) can also be defined and analyzed.
• Guided material selection (automatic material properties) based on section sizes, species and grade.
Resistance factors
• Modification coefficients are determined automatically based on a small number of parameters and selected design code. All coefficients may be defined manually if needed.
• The size coefficients are calculated automatically according to the section sizes.
• The load duration coefficient is determined automatically for each load combination and is applied to the calculation of the wood elements’ resistances.
• The support parameters used in the shear and bearing resistance (compression perpendicular to grain) can be specified. These parameters can be different for the two ends of members.
Technical features
• Detailed results for each shear-wall segment, including the forces in anchors (Rij) and the shear forces (Vf).
• The shear forces on each segment are calculated according to two methods: Shear force distribution based on the stiffness of the shearwall segments and shear force distribution based on the shear resistance of the segments.
• Design of floor diaphragms.
• Account for nails and anchors in shearwalls stiffnesses and lateral deflections.
• Wall design can be carried on the results of a linear, P-Delta, non-linear, seismic or dynamic analysis.
Parametric model generation
• Create wall outlines by clicking two or three points in the 3D environment.
• The wall surfaces can be rectangular or trapezoidal.
• The wall outlines can be copied to create the structure faces and the different stories of the structure.
• Windows and doors opening can be created and stored in a library to be reused for a series of walls.
• The lintel can be positioned directly above the opening or at the top of the wall.
• The opening members can have their sections assigned according to those of the wall or can be selected manually.
• The wall generator creates the members and loading surfaces of the wall and assigns basic properties and wood design parameters to these elements.
• Engineering model is generated automatically based on the wall, openings, sheathing and anchors parameters.
• All wall elements can be edited, which gives full control to the user.
• The walls can either be bearing walls or shearwalls.
• The sheathing parameters and the anchorages configuration can be specified for each wall segment in order to calculate the shear resistance of the shearwall segments.
• Each element in the wall can be made of a simple or built-up wood section chosen by the user. Any type of wood section is allowed.
• Studs are automatically positioned in the wall according to the selected spacing.
