TimberTech Buildings (v2.20161129.2139R.)

New settings for platform frame walls, improvement of the calculation of the connections, new NADs added, new materials added, dxf export improved and new standards for materials added

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

Added new calculation options for the framed walls. The user has now the ability to manually change some of the parameters used in the calculation method proposed in section 9.2.4.2 of EN 1995-1-1: to disable the limitations related to the aspect ratio of the panels in the famed walls, to impose a value of the calculation coefficient ci different from that calculated automatically by the software and to edit the value of the amplification factor of the lateral bearing capacity of the connectors (1,2) suggested by the European standard at paragraph (5). Therefore the user can now adapt the calculation method to the specifications present in some national standards (e.g. Swiss regulations).
Calculation of lateral load bearing capacity of the fasteners in the punched metals plates and straps both for tension and for shear forces: The calculation is performed using the Johansen theory giving the user the possibility to combine a connector (nail or screw) to a plate or a punched metal strap. The software automatically performs a series of checks on the compatibility between the connecting elements (plates) and the fasteners chosen by the user and it uses the correct set of formulas, respectively, for thin or thick plates. The total carrying capacity of the group of fasteners is now calcluated using the effective number of fasteners which is evaluated according to points 8.3.1.1 (8) and 8.5.1.1 (4) of the EN 1995-1-1.
Added the possibiity to use the screws for plates in tensile and shear connections with perforated plates
Improvement of the calculation of timber to timber connections: the user can now choose the method of installation of the metal fasteners (screws and nails): with or without pre-drilling.
New National Application Documents (NAD) added. The NADs of the following countries were added: Bulgaria, Denmark, Estonia, France, Latvia, Lithuania, Norway, Portugal, Spain, Sweden, Switzerland.
XLAM archive updated with new products
Improvement of the dxf exports: the wall elements and the pillars are now exported to the DXF file with the actual dimensions and thicknesses
Solid wood strength values updated: values updated according to EN 338: 2016
Bug fixing and small improvements

Code-design of beams and columns

The solution for design of reinforced concrete beams, columns and ribs has been further extended by reinforcement templates and it now covers the complete workflow:

Definition

Definition of basic amount of reinforcement.
Definition of settings for the calculation of the additional reinforcement
Selection of templates from a library.

Calculation

Calculation of required area of reinforcement or required number of bars of a given diameter
Calculation of shear reinforcement as required area or as required number of legs

Review and check

Comparison of the required area of reinforcement with the limit values stipulated in the code.

Steel connections enhancements

Base plate connections design in full compliance with EN 1993-1-8 including calculation of moment resistance, determination of rotational stiffness, classification of the connection.
The length of anchor bolts is now determined according to EN 1992-1-1 and the strengthening effect of the concrete block around the zone in contact with the base plate is taken into account.
Beam-to-column connection with 4 bolts now calculates the tension resistance of groups of bolt rows.
The built-in libraries have been extended by bolts, screws, nuts and washes according to the latest ISO/EN codes.
Better arranged and clearer report.
