Step joints

Traditional timber joints for transferring compression forces

Step joints are traditional timber connections used to transfer compressive forces. They are not only used in the restoration of historic timber structures, but also provide a simple and effective means of transferring high compressive forces. Modern timber-processing machinery and the use of dry structural timber offer a wide range of applications for step joints.

Register now! After registration, you can use the basic version of Module T04 for the design of step joints free of charge without time limitation. All functions are available free of charge for BauBuche.

Module T04

Module T04 enables the design of single step joints, heel notch joints and double step joints in accordance with DIN EN 1995-1-1:2010-12 in conjunction with the applicable National Application Documents.
