A cantilever beam with I-beam cross-section of length L is defined. The beam has five mass points with masses m acting in X-direction. The self-weight is neglected. The frequencies, the mode shapes and the equivalent loads of this 5-DOF system are analytically calculated and compared with results from RSTAB and RFEM.
Cantilever Beam (SDOF) with Periodic Excitation
Frame Structure Subjected to Earthquake Loading
A two‑storey single‑bay frame structure is subjected to earthquake loading. Modulus of elasticity and cross‑section of the frame beams are much larger than those of the columns so the beams can be considered rigid. Elastic response spectrum is given by the SIA 261/1:2003 standard.
