Book Chapter
Menendez, J., Leitch, K., & Hairstans, R. (2014). Sole plate fixing details for modern methods of timber construction. In S. Aicher, H. W. Reinhardt, & H. Garrecht (Eds.), Materials and joints in timber structures: recent development of technologies (109-118). Springer. https://doi.org/10.1007/978-94-007-7811-5_10

In order to resist lateral loads, modern methods of timber construction are reliant on the in-plane shear strength of the walls orientated parallel to the applied action. In closed panel systems, the shear stresses are transferred to the foundations... Read More about Sole plate fixing details for modern methods of timber construction..
