This paper proposes a new type of variable-cross-section replaceable link that can isolate the plastic deformation. The and frame beam connect with expanding section by bolt along flange web separately. It is easy to design an elastic bolt, reduce slippage, facilitate replacement after earthquake. Considering large deformation range high-strength steel superior link, eccentrically braced variab...

Ducts are used to carry fluid in various applications in HVAC systems, thermal power plants, cement and other process industries. Such ducts are generally subjected to failure due to cyclic stresses either caused by high temperature fluctuations, mechanical vibrations or due acoustic vibrations caused due to the fluid flowing through the ducts. In this paper we study the failure of one such duc...

In this paper we construct a numerical solver for the Saint Venant equations. Special attention is given to the balancing of the source terms, including the bottom slope and variable crosssectional profiles. Therefore a special discretization of the pressure law is used, in order to transfer analytical properties to the numerical method. Based on this approximation a wellbalanced solver is deve...

The spatial impulse response of a single variable-cross-section photoreceptor has been characterized assuming the incoming radiation to be an initial field propagating under confinement conditions inside the receptor. By application of Fourier analysis the total transfer function is determined. Both the outer and the inner segments are characterized as low-pass filters. The dependence of the tr...

Multilayered microresonators commonly use sensitive coating or piezoelectric layers for detection of mass and gas. Most of these microresonators have a variable cross-section that complicates the prediction of their fundamental resonant frequency (generally of the bending mode) through conventional analytical models. In this paper, we present an analytical model to estimate the first resonant f...
