Using the “Timber joist floor slabs” module, CYPECAD analyses and designs timber joist floor slabs.
More information on other timber structural elements that are included in the “Timber sections” module (for CYPECAD and CYPE 3D) can be found on the “Timber sections” webpage.
CYPECAD allows users to define, analyses and design timber joist floor slabs and timber beams. These structural timber elements are included in the “Timber joist floor slabs” and “Timber sections” modules, respectively.
The “Timber sections” module is for use in CYPECAD and CYPE 3D, and allows users to analyse and design structural beam-type timber elements and generic-type timber elements. More information on the “Timber sections” module, for use with CYPECAD and CYPE 3D can be found on the “Timber sections” webpage.
The codes implemented for the design and check of the timber joist floor slabs and beams are:
To adapt the program to the current market, timber sections have been created, distinguishing between sawn timber and laminated timber, and including the DUO/TRIO series, which are currently very much in use.
The data CYPECAD will use to analyse the timber elements (joists, beams and bars of integrated 3D structures) is defined in the “Timber” dialogue box (Project > General data > Timber):
Users can select timber joist floor slabs in the “Joist floor slabs” menu in the “Panel manager” dialogue box (Slabs > Panel manager > Define panel).
The following data must be defined for a joist floor slab:
The sections that make up the timber joists are designed for simple bending, because due to the rigid diaphragm hypothesis, axial forces and forces in the plane of the floor slab are not considered.
Following this criteria, the program selects the first joist of the selected series that does not fail any resistance or deflection checks, as long as the maximum depth (defined by users) is not exceeded.
From the “Joists” menu in the “Results” tabs, users can access the worst-case report of the joist. This report includes a table with the deflection checks of the timber joists.
The deflection checks for timber joists are obtained considering:
The program carries out the fire resistance check of timber joists using the “Fire resistance check” module, used by CYPECAD and CYPE 3D, and also carries out the check for other structural timber (timber beams and other generic-type timber structural elements), steel and concrete elements.
The data that has to be defined for CYPECAD to be able to check the fire resistance of timber joists and beams is introduced in the “Fire resistance check. General data” dialogue box (Project > General data > Loads > Fire resistance check).
In this dialogue box, users have to define, for each floor group:
It is possible to defined different data for a specific zone in a group of floors using the options of the Fire resistance window (Groups > Fire resistance from the Beam Definition or Results tab).
More information on this module, for use with CYPECAD and CYPE 3D, can be found on the Fire resistance check webpage.
For CYPECAD to be able to analyse and design timber joist floor slabs, the user licence must include, as well as CYPECAD, the “Timber joist floor slabs” and “Joist floor slabs (generic concrete joists)” modules.
If, users also wish to check the fire resistance of these elements, they must also hold the “Fire resistance check” module permits.
CYPECAD is available in its unlimited version and also in two limited versions called LT30 and LT50, which contain the same tools and module acquisition possibilities, but have the following conditions:
Integrated 3D structures of CYPECAD (also LT50 and LT30) is not technically a module. To define these 3D structures in CYPECAD, users must also have the required permits to use CYPE 3D in their user license and, optionally, modules which are exclusive to CYPE 3D.
The following modules are those that can be acquired together with CYPECAD or CYPECAD LT:
