In the first part of this paper, elastostatic stability of cracked conservative flanged concrete
beam-columns has been analyzed. Using the derived expression for the lateral stiffness …

Purpose: Purpose of this paper is the theoretical formulation of elasto-dynamics behaviour of
fully cracked concrete beams for two-degree of freedom (DOF) dynamical system. Such …

We study the nonlinear response of a certain parametrically driven bistable oscillator that is
subjected to two external periodic drives of widely different frequencies. We observe …

When structures are subjected to dynamic types of loads, cracks are fairly consistent. Under
dynamic loads, such structures exhibit nonlinear and inelastic behaviour. If a suitable load …

In this two-part paper, a new class-first order homogeneous dynamical (FOHD) systems-of
two-DOF conservative nonlinear dynamical systems has been explored. Theoretical …

When subjected to time-dependent dynamic loading, concrete structures possess tension
cracks. Such existing internal cracks have a breathing action (opening-closing-reopening) …

In a weakly nonlinear oscillator driven by an external periodic force, the response is
generally amplified near the natural frequency of the system and the response at all other …

This Ph. D. thesis consists of the analysis of nonlinear response of certain oscillators under
the influence of bi-harmonic forces of widely different frequencies (slow and fast frequeney) …

In an earlier paper, authors have investigated the static and dynamic stability of cracked
concrete flanged conservative beam-columns. The cantilever column with a lumped mass at …
