Wall blocks
Design parameters
Axial properties
Where \(N_{rd}\) is the axial capacity and \(k_a\) is the axial stiffness.
Lateral load resistance
The lateral capacity of WikiHouse walls can be calculated using the following spreadsheet.
For more information, a tutorial is provided below:
Reference values for a 2.4 m high walls are reported in the table below.
Where \(q\) is the vertical load, \(h\) is the height of the wall, \(F_{300}\) is the lateral force resulting in h/300 lateral displacement and \(F_{ULS}\) is the lateral load capacity.
Useful formulae
Pressure capacity of the external panel
The pressure capacity \(\rho_{rd}\) of the external panel is equal to:
\( \rho_{rd}=\min\begin{cases}\frac{f_s}{376}\\\frac{1}{\frac{4700}{9f_s}+\frac{235000}{81f_{t,0}}}\end{cases} \)
where \(f_s\) is the shear capacity of the material and \(f_{t,0}\) is the tensile capacity of the material parallel to the grain.
How these values\formulas can be used?
These values can be used for design purposes. Please check the worked examples section for more details.
Where do these values\formulae come from?
These values come from an experimental testing and analytical modelling. Please check the research library (specifically article 1, article 2 and article 3) for more details.
