===== General Program build-up =====

==== Modules ====

Currently the CLTdesigner consists of 9 modules.

The [[en:clt:hotspot:software:cltdesigner:manual:modul_plate1d_continuousbeam|Module „CLT-Plate 1D - Continuous beam“]] offers the required verifications for the ultimate limit state (ULS) with respect to bending and shear for permanent and transient loads as well as accidental (fire) design situations, and the verifications for the serviceability limit state with respect to deflection and vibrations according to EN 1990 or EN 1995 for continuous systems such as cross laminated timber plates.

After specifying the internal forces and buckling lengths, the [[en:clt:hotspot:software:cltdesigner:manual:modul_plate1d_internalforces|Module „CLT-Plate 1D - Internal forces“]] carries out the required verifications of the ultimate limit state with respect to normal and shear forces for permanent and transient loads as well as accidental design situations.

The [[en:clt:hotspot:software:cltdesigner:manual:modul_plate_in_plane|Module „CLT-Plate loaded in plane“]] carries out the required shear stress verifications for a CLT cross-section in the ultimate limit state for permanent and transient loads as well as for accidental design situations based on a given shear force in plane per unit length.

The [[en:clt:hotspot:software:cltdesigner:manual:modul_compression_perpendicular_to_grain|Module „Compression perpendicular to grain“]] calculates the k<sub>c,90</sub>-coefficients for various load situations (point or line load introduction or transmission) and carries out the required verifications.

The [[en:clt:hotspot:software:cltdesigner:manual:modul_tbeam|Module „Ribbed slab“]] offers the required verifications for the ultimate limit state (ULS) with respect to bending and shear for permanent and transient loads, and the verifications for the serviceability limit state with respect to deflection and vibrations according to EN 1990 or EN 1995 for ribbed slabs made of CLT plates with ribs of GLT or solid wood.

The [[en:clt:hotspot:software:cltdesigner:manual:modul_horizontal_force_distribution_on_shear_walls|Module „Horizontal load distribution on shear walls“]] calculates the distribution of horizontal loads from wind or earthquake on the load-bearing wall elements.

The [[en:clt:hotspot:software:cltdesigner:manual:modul_stiffness_matrix|Module „Stiffness matrix“]] calculates the stiffness values necessary for a two-dimensional FE calculation and offers an export opportunity to Dlubal RFEM 5.

The [[en:clt:hotspot:software:cltdesigner:manual:modul_sherpa_clt_connector|Module „SHERPA CLT-Connector“]] calculates connections of cross laminated timber elements with the SHERPA CLT-Connector according to the European Technical Assessment ETA-18/0083.

The [[en:clt:hotspot:software:cltdesigner:manual:modul_wall|Module „Wall“]] offers the required verifications for the ultimate limit state (ULS) of walls under vertical and horizontal loads as well as wind perpendicular to the wall plane (cold and hot dimensioning).

==== Buttons ====

{{clt:hotspot:software:cltdesigner:manual:prefsinfohelp_buttons.png|Settings/Preferences, Information and Help}}

A window with [[#Settings/Preferences|settings/preferences]] will open by clicking on the left button in the first series of buttons, another window with [[#information]] about the CLTdesigner will pop up by clicking on the middle, and help information can be accessed by clicking on the right button.

By clicking on one of the buttons in the second series of buttons shown in the following figure, the language can be changed. The current version offers German, English, French, Italian, Spanish and Dutch translations.

{{clt:hotspot:software:cltdesigner:manual:language_buttons.png|Available languages (DE, EN, FR, IT, ES, NL)}}
==== Settings/Preferences ====

{{ en:clt:hotspot:software:cltdesigner:manual:preferences_toolbar.png |Preferences}}

The settings are divided into the categories:

  * General
  * Loads
  * Analysis
  * Verification
  * Documentation

Within the category **General**, it can be specified if the single pages of the report (pdf format with security settings) should be also exported as pictures and if so, in which format (png or jpg). Furthermore, by ticking the second box, one can (de)activate the warning notice for the symmetry conditions of the cross-section. The default units of the cross-section properties can be changed by clicking the "Units..." button.

{{ en:clt:hotspot:software:cltdesigner:manual:preferences_general.png |Preferences - General}}

The settings regarding the type of calculation for the dead load, as well as the type of load position can be configured within the category **Loads**. The load combinations can be also adjusted here. As for the combination factors, they can be chosen according to EN or NA, but can be also user-defined. Furthermore, an option is offered here to simultaneously apply either snow load or wind actions together with the imposed load on roofs (category H). For the automatic generation of load combinations, it is also necessary to define whether the distributed and single loads should be considered as a one load group. This is due to differences which arise in combinations where the leading actions come from variable loads.

{{ en:clt:hotspot:software:cltdesigner:manual:preferences_loads.png |Preferences - Loads}}

The method of analysis can be chosen within the category **Analysis**. Currently, three approaches are provided: (i) shear analogy method, (ii) Timoshenko beam theory and (iii) γ-method. The number of calculation points of the field can be specified in two ways: either by specifying the number of subdivisions of the fields or by specifying the maximum size of the subdivisions. When selecting the latter one, it needs to be further chosen between the height of the plate (element size according to selected cross-section) and a fixed element size.

Furthermore, here you can specify whether the modulus of elasticity E<sub>90</sub> should be ignored in the calculation.

{{ en:clt:hotspot:software:cltdesigner:manual:preferences_analysis.png |Preferences - Analysis}}

It is also necessary to specify whether the National Annex should be considered in verification and if so, which one. Furthermore, partial safety factors for the ULS verification need to be specified by selecting either EN, NA or user-defined from a drop-down list. The user also can specify whether the system coefficient k<sub>sys</sub> should be taken into account or not. For the proof of stability, the imperfection coefficient β<sub>c</sub> and the conversion factor mean value to 5% quantile value k<sub>05</sub> as well as the consideration of the shear deformation can be defined here.

{{ en:clt:hotspot:software:cltdesigner:manual:preferences_verification_uls.png?675 |Preferences - Verification - ULS}}

The deformation factors (values according to either TU Graz, EN, NA or user-defined), as well as the limit values for deformation need to specified in the "Deformations" tab within the subsection regarding the SLS verification. By ticking the first box, the weight of the plate g<sub>0</sub> will not be considered in calculation of instantaneous deformation w<sub>inst</sub> at t=0. Furthermore, here can be also specified whether the Base Document should be taken into account in deformation analysis or not. Likewise, here is also given an option to neglect short cantilevers in deformation analysis.   

{{ en:clt:hotspot:software:cltdesigner:manual:preferences_verification_sls_deformation.png |Preferences - Verification - SLS - Deformations}}

Additional verifications of vibration can be activated in the **Vibration** tab. In addition to verification according to Eurocode 5, other implemented analysis include: the simplified verification according to DIN (w<sub>perm</sub> ≤ 6 mm), the verification according to suggestion of Hamm/Richter given in the BSPhandbuch, as well as its modified form. Furthermore, here is offered an option to include or neglect the shear deformation in calculations of the natural frequency and/or the deformation w(1kN) or w(2kN) at the stiffness criterion.

{{ en:clt:hotspot:software:cltdesigner:manual:preferences_verification_sls_vibration.png |Preferences - Verification - SLS - Vibration}}

In the **Documentation** settings, one can choose whether, and if so, which detailed results should be included in the pdf report as an appendix.
