Forced vibration of non-uniform beam with nonlinear boundary condition is studied in this paper by proposing an iterative model combining Adomian Decomposition Method and modal analysis. An exponentially tapered a hardening nonlinearity spring simulated as case study. The accuracy proved comparing iteration results analysis solutions linear weakly conditions. Sin-weep frequency spectrum then ob...

This paper aims to investigate the plastic response of reinforced concrete tapered beams when subjected random steel reinforcement volumes, using both deterministic and probabilistic analyses, with complementary strain energy as a boundary in first case, reliability index second. The step this study was use previously studied model perform analysis, assuming that is limiting factor controller b...

The performance of tapered iron bolt (TIB) shear connectors and their feasibility to be used in demountable composite beams are investigated this study. typical TIB connector consists six components, i.e., a connecting bolt, conical plug, top covering plate, fixing retaining washer inner sleeve. expected 1) reduce the initial slip between concrete slab steel beam, which generally exists for ste...

In this study, the free vibration analysis of a functionally graded (FG) micro-beam with tapered cross-section is carried out theoretically. The beam has material distribution according to power law throughout thickness. governing equation reduced an ordinary differential for cross-sectional geometry whose width varies exponentially. Vibrations microbeams were analyzed analytically in elastic v...

In this article, crashworthiness performance and crushing behavior of tapered structures with four internal reinforcing plates under axial and oblique dynamic loadings have been investigated. These structures have a tapered form with five cross sections of square, hexagonal, octagonal, decagon and circular shape. In the first step, finite element simulations performed in LS-DYNA were validated ...
