Comparative Analysis Of Cellular Beam And Honeycomb Beam With Anasys Program

open access: yesJurnal Mekintek : Jurnal Mekanikal, Energi, Industri, Dan Teknologi, 2021
Steel is one of the most widely used construction materials. Along with the development of technology in the field of construction, many variations have been made in the use of steel as a construction material to make it more suitable for the needs and economical in terms of cost.

Behavior of cellular beams protected with intumescent coatings

open access: yesFire Research, 2016
A new engineering practice in modern buildings is to use beams with web openings to allow the passage of services within the depth of the beam instead of underneath the beam. As the web post failure may occur before the section reaches the limiting temperature, usually an increase in the fire protection may be required for members with web openings in ...

Lateral distortional buckling of cellular composite-beams [PDF]

open access: yesRevista IBRACON de Estruturas e Materiais, 2018
Abstract In the region of negative bending moments of continuous and semi-continuous steel and concrete composite beams, the inferior portion of the steel section is subjected to compression while the top flange is restricted by the slab, which may cause a global instability limit state know as lateral distortional buckling (LDB) characterized by a ...

Fast Cell Discovery in mm-wave 5G Networks with Context Information

open access: yes, 2017
The exploitation of mm-wave bands is one of the key-enabler for 5G mobile radio networks. However, the introduction of mm-wave technologies in cellular networks is not straightforward due to harsh propagation conditions that limit the mm-wave access ...
