Vibrations with Coulomb Friction

A simple oscillator consists of mass m (considered only in x-direction) and linear spring of stiffness k. The mass is embedded on a surface with Coulomb friction and is loaded by constant-in-time axial and transversal forces.

Scaffolding Nodal Support – Diagram with Gap

Consider a rigid scaffolding tube, fixed at the bottom using the Scaffolding Nodal Support and loaded by both a moment and a force. Calculation of the maximum deflection with consideration of slippage in the begin.

Scaffolding Nodal Support – Overcoming the Limit

Consider a rigid scaffolding tube, fixed at the bottom using the Scaffolding Nodal Support and loaded by both a moment and a force. Calculation of the maximum deflection by exceeding the capacity of the scaffolding support.

Scaffolding Tube Connection – Hinge

VE 0057 2015年12月23日 RFEM 几何线性分析 结构非线性

Consider a scaffolding tube connection subjected to an axial force and a moment. Self-weight is not considered. The material of the tube is idealised as perfectly rigid. All geometrical non-linearities are ignored.

Scaffolding Nodal Support

Consider a rigid scaffolding tube, fixed at the bottom using the Scaffolding Nodal Support and loaded by both a moment and a force.
