27/01/2021 – Ver. 83 – New module for the seismic risk classification of the buildings, the Soltech connections were added and the Essepi CLT panels were updated

In the latest version of the software we added these new features:

  • Seismic risk classification module: thanks to the additional module “Seismic risk classification of the constructions” now you can modify the magnitude of the seismic action used in the analysis by defining the percentage of modification of the maximum horizontal acceleration of the soil ag. It is also possible to automatically calculate the capacity Peak Ground Acceleration PGAc of the building and print the seismic risk classification certificate. The calculation method used is the conventional method of Annex A of the Italian Ministerial Decree n° 58 of 28 February 2017 and subsequent amendments “Guidelines for the classification of the seismic risk of buildings”.
  • Essepi CLT panels updated: we updated the stratigraphy of the Essepi CLT panels and the material properties in accordance with the new ETA
  • Soltech connections added: the range of Soltech connections and anchors is now available, including hold-downs, angle brackets, punched metal plates, screws, nails and staples.
  • Bug fixing and small improvements



22/09/2020 – Ver. 81 – New Borga Italia and Simpson Strong-Tie connections, automatic calculation of loads in San Marino, Pfeifer CLT panels added, updating of Stora Enso CLT panels, improvement of the vibration checks of the floors, addition of the national annexes of Romania and added the possibility to insert loads and frame thicknesses lower than in previous versions

In the latest version of the software we added new features:

  • We added the possibility to define the geographical position within the Republic of San Marino. If the user geolocates the building within the territory of the Republic of San Marino, the software automatically calculates the actions acting on the building: wind, snow and seismic action.
  • We added new connections to the archives: Borga Italia and Simpson Strong-Tie. Specifically, the new connections by Borga Italia and some new connections by Simpson Strong-Tie have been added.
  • We added Pfeifer CLT panels to software archives
  • We updated the CLT archives with the new Stora Enso data
  • Improvement of the vibration checks of the floors: we added the possibility to take into account the transverse bending stiffness of the floor also for the calculation of its fundamental frequency f1. In the previous version, the transverse load-carrying effect was considered only in the calculation of the effective width.
  • We added the Romanian standard. The National Annexes of Romania have been added
  • Changes to the input data – values of the acting loads: it is now possible to use values of loads lower than the default ones proposed by the Eurocodes to better adapt to local standards
  • Changes to the input data – width of framed wall elements: it is now possible to use studs and frame elements with a width of less than 40 mm to better adapt to customer needs
  • Bug fixing and small improvements


28/05/2020 – Ver. 79 – Fire protections added to the fire module and Egoin panels added to CLT archives

In the latest version of the software we added new features:

  • Fire protections: checks on the load-bearing function of structural members initially protected from exposure to fire can now be performed. Gypsum Plasterboard, Gypsum Plasterboard Type F, Gypsum Fibreboard and custom definitions can be used. In the first three cases, the software automatically calculates the time of start of charring tch, the failure time of protection tf (evaluated differently for vertical and horizontal elements), the time tand the insulation coefficient k2. In the case of custom definition, the designer can manually enter the parameters in order to manage protection solutions not listed in the standard or defining specifications of a particular manufacturer. For all protected structural elements, the rules proposed in EN 1995-1-2 are used with all the cases proposed by the standard for the calculation of the charring depth dchar,n, the calculation of k0 and k2 and the calculation of the effective charring depth deff.
    The joist floors and the framed walls with protections are calculated as assemblies with void cavities following the indications of Annex D of Eurocode EN 1995-1-2, which provides for different times of start of charring for the sides directly exposed to fire and for the sides facing the empty cavities.
  • CLT panels by the Spanish manufacturer Egoin added: it is now possible to check the CLT structures made with Egoin panels


12/02/2020 – Ver. 78 – LVL and Uso Fiume Trieste new materials, improvement of the databases translations and of the reactions in foundation export, spreadsheet for the interstorey drift sensitivity coefficient, new welcome page

In the latest version of the software we added new features:

  • Inclusion of LVL: both softwood and beech LVL are now available and they can be used as beams, columns, joist floors and solid wood floors. The databases include the products of the main European manufacturers: Metsa Wood (Kerto), Steico e Pollmeier (BauBuche e Fichte LVL).
  • Improvement of the reactions in foundation export: inclusion of two new fields in the “actions.csv” file providing the name and the length of the element in each node. Inclusion of three new layers in the “geometry.dxf” file displaying the nodes numbers, the walls lines and the names of the elements in each node.
  • Improvement of the databases translations: all the databases are now consistently translated and they support the transition of the software from Italian to English version and viceversa.
  • Inclusion of Uso Fiume and Uso Trieste timber: softwood and chestnut Uso Fiume timber and softwood Uso Trieste timber are now available and they can be used in beam, column and joist elements according to their ETA specifications.
  • Spreadsheet for the calculation of the interstorey drift sensitivity coefficient: the users can now download form their Personal area the spreadsheet for the calculation of the interstorey drift sensitivity coefficient for the assessment of the second-order effects.
  • New welcome page: the software shows an interactive welcome page that will host constantly updated contents such as papers, events, blog posts, software updates and tutorial videos.


13/11/2019 – Ver. 77 – Fire design add-on module, improvement in the management of extended and polygonal walls, improvement of the calculation report

In the latest version of the software we added new features:

  • Verification of the timber structural elements in fire conditions: it is now possible to perform the resistance checks in fire conditions of the unprotected structural timber elements.
    The development of an update to include fire protection layers in the analysis and verification process is already in progress.
    For further information on the fire design module please click here.
  • Improvement in the management of extended and polygonal walls: extended and polygonal walls can now support floor, roof and wall elements according to more complex configurations.
  • Improvement of the formatting of the calculation report.



25/09/2019 – Ver. 76 – Simpson Strong-Tie connections and Binderholz CLT update

In the latest version of the software we have added the following new features:

  • Inclusion of Simpson Strong-Tie connections: a selection of Simpson Strong-Tie connections with all the relevant strength and stiffness parameters is now available in TimberTech Buildings. The selection includes hold-downs, timber-to-timber shear and tensile plates, timber-to-concrete shear plates and timber-to-timber and timber-to-concrete angle brackets with the appropriate fasteners and anchors.
  • Binderholz CLT update: two material are now available for Binderholz CLT: BBS 125 and BBS XL. The user can choose the appropriate material according to the panel type.
  • Bug fixing and small improvements
