2D frame analysis

Solve a plane frame from nodes, members, supports, and loads.

Enter your values, then calculate.

Calculation method

Assemble transformed 6×6 frame stiffness matrices; solve Kff·uf=Ff and recover reactions Ku−F and member end forces. Distributed loads vary linearly along each member.
