Analytical estimation of the first natural frequency and analysis of a planar regular truss oscillation spectrum
A statically determinate truss of a beam type with a triple lattice with short descending and long ascending braces is considered. The mass of a truss is modeled by concentrated loads at its nodes. For the first natural frequency, the Dunkerley’s method derives a formula for the dependence of its lo...
