... Generalized finite element method Framed structures Free vibration Isogeometric analysis Enriched methods The finite element method (FEM) is widely used in the solution of engineering problems and has been a successful alternative to find natural modes and frequencies (Bathe, 1996). However...

...A. Kaveh; L. Shahryari Purpose The purpose of this paper is to describe how the method recently developed for mass‐spring systems and frame structures is modified to include the free vibration of trusses. Design/methodology/approach Here, two methods are presented for calculating...

...Boris Trogrlic; Ante Mihanovic Purpose This paper aims to present a new numerical model for the stability and load‐bearing capacity computation of space reinforced‐concrete (R/C) frame structures. Both material and geometric nonlinearities are taken into account. The R/C cross‐sections are assumed...
