WOODexpress. Structural Timber design software. A program for design and
dimensioning of timber components, and timber roofs according to Eurocode 5
(EC5). In a graphic environment you
design roof trusses and elements of timber structures. WOODexpress simplifies all the repetitive and time-consuming every
day calculations for timber elements and timber roofs. Detailed report with calculations, automatic generation of truss
drawings and details of connections.
To design a timber component or truss, choose from ready roof models,
specify the main dimensions, loads, design code parameters, and the design is immediately
performed and drawings produced automatically. Default values and checks for erroneous
input values, facilitate the input data process. The report, which is created
simultaneously, shows in detail all the calculations and the design steps with references
to the corresponding design code paragraphs. Clear warnings informs you in case of
The material properties, the loads and the design code parameters, timber sections, can be
adjusted by the user according to the requirements of the National application document.
A context-sensitive Help system, guides you through the use of the program and the
Eurocode provisions. On-line user's manual and frequently asked questions (F.A.Q.) are
included in the program.
close coupled roofs
trussed rafter roofs
trusses with carpentry joints
design is based on a finite element analysis of the truss structure. The truss is
considered as a two dimensional frame structure, and the stiffness of the connections is
adjusted according to the selected degree of stiffness. The natural frequencies of the
roof trusses are computed from a dynamic analysis.
The loads are evaluated according to Eurocode 0 and 1.
All the load combinations are taken into account.
The checks are performed for the most unfavourable loading conditions, for combined action
in ultimate limit state of design, according to EN 1995-1-1:2008,
The deflections are checked in serviceability limit condition, according to EN
The connections are considered as nailed,
bolted or screwed joints with metal plates and are dimensioned according to EN
generation of truss drawings. Detailed drawing of the truss structure and the connections are automatically
produced. A specialised CAD modulus is included to customise, preview and print the
drawings. Export to DXF and PDF files.
Dimensions You specify the main roof dimensions (length, high or pitch). You
can choose to specify dimensions at
nodal points or at element ends.
Cross section sizes are chosen from the various tables included in the program. Tables with
section sizes from different European countries are included in the program, and you can
also specify you own.
End cantilevers can
be added on the sides.
various nodes can be selected.
Roof covering loads
The program includes most of the common roof covering materials. You can also specify your
own types of roof loading.
Snow loading is evaluated according to
Eurocode 1, EN 1991-1-3-2003. You specify the characteristic
snow load value on the ground in
[kN/m�]. Snow guards at the right or left side can be
Wind loading is
evaluated according to Eurocode 1, Actions on structures, EN 1991-1-4:2005. You
specify the wind pressure on a vertical surface in
Load combination is according to Eurocode EN 0, Basis of structural design
EN 1990:2002. You can
adjust the action and load combination factor.
Connections properties you can specify are:steel plate type, regular or BMF,
plate thickness, the degree of stiffness of connections, the type and size of the
You can also select to use single or multiple plates in the joints with more than two
Splices are designed automatically for long timber members.
You can design various types of bolted, nailed and screwed connections.
Specify the properties of the bolts, nails or screws, and the properties of the connection
wood or metal plate, and the Capacity Rd is computed according to Eurocode 5, EN
Ultimate limit states
Design of various cases of single or combined action according
to Eurocode 5, EN 1995-1-1:2004
� 6, round and rectangular sections.
The design objects are independent
objects and each one has its own drawings, material properties and computations
Structural fire design Structural
fire design is performed for every stress case. The structural fire design is performed
according to Eurocode 5, part 1-2, reduced cross section method..
Floors The internal forces are computed at the ends and the middle span of the
floor beam and the elastic bending deformations at midspan, for all the load combinations
according to Eurocode 0, 1 and 5.
All the checks of Eurocode 5, EN 1995-1-1:2004,
6 are performed in
ultimate limit state.
The deflections are checked in serviceability limit state according to
Eurocode EN 1995-1-1:2004, �7.
The Eurocode EN 1995-1-1:2004,
7.3. considerations are taken into account
for the check of beam vibrations.
From the menu parameters you can adjust the default
dimensions, section sizes, material properties, loads and code parameters.
Timberstrength classes from tables according to EN338:2003
Softwood/Hardwood, 1194:2000 Glulam, included in the program. You can also specify user
defined tables with timber strength classes.
Section properties tables according to the Eurocode standard EN 1313-1, from
European countries, are included. You may also specify user defined tables with
The most common used roof covering loads are included in the program. You can modify or add roof
coefficients for permanent
and variable loads in unfavourable loading conditions according to Eurocode 1,5. The user
can adjust the action coefficients.
Eurocode version For timber design, snow and wind
loads you can choose the Eurocode versionto be used in the design, according
to which code is applied in your country.
A detailed report is produced, showing analytically all the computations,
drawings, design steps, design assumptions and references to the corresponding design code
paragraphs. Warnings in red appear in the report in cases of inadequate design.
The report contains all the objects that are
checked in the design objects window. The order of the objects appearing in the report can
Adjustments for the report, font, margins,
logo of caption or footnote, etc. can be done from the menu Report Setup.
