Combined Bending and Axial Compression
Cross-sectional Inputs
All references to EN 1995-1-1:2004
unless otherwise stated.
This tests a cross-section in combined compression parallel to the grain and biaxial bending around the y-y and z-z axes according to Clause 6.2.4
.
Timber type
The timber type of the cross-section. See the timber database section for the types supported by Teretron.
Cross-section type
The geometry type of the cross-section.
Width bThe width of a rectangular cross-section, in mm. Depth hThe depth of a rectangular cross-section, in mm. |
||
Diameter dThe diameter of a circular cross-section, in mm. |
Area A
The area of a generic cross-section, in mm2.
Section modulus Wy
The section modulus of the cross-section about the y-y axis, in mm3.
Section modulus Wz
The section modulus of the cross-section about the z-z axis, in mm3.
Area reduction
The area reduction ΔA refers to reductions in the nominal cross-section size that have to be taken into account in the calculation of the member strength (e.g. holes from fasteners) according to Subclause 5.2(2)
.
It should be given as a percentage of the total nominal area of the cross-section.
Section modulus reduction
The section modulus reduction ΔW refers to reductions in the nominal cross-sectional modulus that are to be taken into account in the calculation of the member strength (e.g. holes from fasteners) according to Subclause 5.2(2)
.
It should be given as a percentage of the total nominal section modulus of the cross-section.
Contribution of cross-section size on the determination of member strength properties
Includes factors kh for the calculation of the member strength in solid timber, glulam and LVL, according to Clauses 3.2
, 3.3
, and 3.4
.
Contribution of the load distribution system in the member strength properties
Includes factor ksys for the calculation of the member strength, according to Clause 6.6
, for a member that functions as part of a continuous load distribution system.
Note that Subclause 6.6(3)
states that the strength verification for a continuous load distribution system should be carried out assuming short-term load duration.
