Abstract

This paper presents the results of a study conducted to investigate the effect of small transverse hole on the shear capacity of slender beams. A total number of ten beams were cast, with concrete grade of C13.02. The cross -sectional dimensions of the beams were 100mm x 150mm, with an effective span of 560mm. The tested beams consisted of two control beams. The experimental beams consisted of eight beams, four of the beams were with 20mm service hole (two beams with holes at the centre and two beams with holes at 220mm from both ends), while the other four had 25mm service holes, with two of beams had holes at the centre, while the other two beams had holes at 220mm from both ends. The beams were subjected to both point load and load at third points. The study shows that the ultimate load of beams with service holes depends on the size of holes, position of holes, and of type loading.

Abstract

The interplay between interference and absorption leads to interesting phenomena like coherent perfect absorption and coherent perfect transparency (CPA and CPT), which can be exploited for fully optical modulation. While it is known that it is possible to harness CPA and CPT for switching a strong signal beam with a weak control beam, it is not immediate that this process su ers from a fundamental compromise between the device e ciency (quantified by device loss and modulation depth) and the asymmetry between signal and control intensity desired for operation. This article quantifies this compromise and outlines a possible way to overcome it by means of a combination of optical gain and loss in the same photonic component. A general formulation and a specific device realization are both discussed. © 2018 Optical Society of America.
