In the presented paper, the governing equations of a vibratory beam with moderately large deflection are derived using the first order shear deformation theory. The beam is homogenous, isotropic and it is subjected to the dynamic transverse and axial loads. The kinematic of the problem is according to the Von-Karman strain-displacement relations and the Hook's law is used as the constitutive eq...

We study the construction of nonlinear impulse responses in linear structural dynamic models that include nonlinearly transformed regressors. derive closed-form solution for population to a given shock and propose control function approach estimating these without taking stand on how remainder model is identified. Our plug-in estimator dispenses with need simulations and, unlike conventional lo...

Assembling nonlinear dynamic models of structures is the goal of numerous research and development organizations. Such a predictive capability is required for the development of advanced, high-performance aircraft structures. Specifically, the ability to predict the response of complex structures to aero-acoustic loading has long been a United States Air Force (USAF) goal. Sonic fatigue has pla...

In this article, we tried to emphasis in how the range of torsionally stiff and flexible single story buildings works. The designed base was according to provisions of the Canadian standard, 2005 NBCC. The behavior of nonlinear dynamic time history of eight building models subjected to seven horizontal bi-directional ground motions compatible with design spectra are investigated. These models c...

Incremental Dynamic Analysis (IDA) procedure is now considered as a robust tool for estimating the seismic sidesway collapse capacity of structures. However, the procedure is time-consuming and requires numerous nonlinear response-history analyses. This paper proposes a simplified Modal Pushover Analysis (MPA) procedure for IDA of RC moment-resisting frames. The proposed method uses the dynamic...

Poly(1,8-octanediol-co-citric acid) (POC) is a synthetic biodegradable elastomer that can be processed into three-dimensional (3D) scaffolds for tissue engineering. We investigated the effect of designed porosity on the mechanical properties, permeability, and degradation profiles of the POC scaffolds. For mechanical properties, scaffold compressive data were fitted to a one-dimensional (1D) no...

Placing column lap-splice in the locations of possible nonlinear deformation may adversely affect the structures response to strong ground motions. Localization of damage in splice zone may change the structural response and prevent the load redistribution and development of a uniform pattern of nonlinear excursions among the various members. Validated by existing laboratory experiments, this s...
