Estudio del comportamiento no-lineal de columns tubulares rellenas de hormigón frente a cargas laterales

, 2018
Los elementos diagonales se emplean para aumentar la rigidez en edificios de altura o en forjados horizontales de grandes luces, formando celosías. Cuando estos elementos forman parte del sistema disipador en un evento sísmico, se producen lazos de histéresis asimétricos, debido a la diferencia del comportamiento en tracción y compresión, donde ...

Impacto de comportamiento no lineal del varactor en amplificadores modulados por la carga a la salida

, 2011
In this paper, the impact of the nonlinear characteristic of the varactor capacitance on the intermodulation distortion (IMD) profiles of voltage controlled impedance transformation networks, is presented. A test set-up for dynamically measuring the Taylor series expansion coefficient is proposed, able to be extended to the ...
