A few principles of connection A few principles of connection designdesign

• Keep the load path as direct as possible

• Connect the loaded fibres• Avoid tension perpendicular to grain

stresses• Make use of compression load transfer

as much as possible• Use steel elements when tension load

transfer is necessary
