A new method that involves interference between two unequal beams in a single writing scan is proposed and demonstrated to be able to improve the index profile and the spectral response of fabricated FBGs.
All of the beams tested in each series had the same dimensions with simple supports, unequal reinforced concrete beam lengths and two external steel plates; they were loaded with a central point load.
In this paper, an accurate dynamic stiffness model for a three-layered sandwich beam of unequal thicknesses is developed and subsequently used to investigate its free vibration characteristics.
An exact dynamic member stiffness matrix (exact finite element), which defines the flexural motion of a three-layered sandwich beam with unequal faceplates, is developed from the closed form solution of the governing differential equation.
Considering architectural issues, mostly two adjacent bays with different lengths are exerted in a structural framing, thus two beams with unequal depths are applied and lower ICP can be used to connect the bottom flanges of deep and shallow beams.
From Eq. (57) above, the deflection (w) of the sandwich beams with unequal lengths can be calculated by integrating four times with respect to (x).
It is shown, by means of several illustrative examples, that this may not be the case for I-section beams with unequal flanges (monosymmeric cross-section – symmetry with respect to the minor axis).
This research aims to estimate the ultimate capacity and seismic demand of inclined continuity plate (ICP) connected to beams with unequal depths which are utilized in special moment resisting frames (SMRFs).
We present a numerical model validated against the laboratory test data to conduct parametric studies that investigate the range of slenderness values for which the CSM is beneficial, and to examine the interaction between beam segments with unequal loads.
Each series of tests consist of four combinations of two levels of total axial load in the column, with either equal or unequal loads on the connected beams.
