A study on the behavior of beam-column connections in precast concrete structures: experimental analysis

open access: yesRevista IBRACON de Estruturas e Materiais
Due to the large increase in the use of precast concrete structures in multistory buildings, this work covers a study on the behavior of beam-column connection with emphasis on the continuity provided by the slab reinforcement. Two prototypes were tested,

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

Experimental behavior of connection between composite columns and reinforced concrete flat slab

open access: yesJournal of Engineering and Applied Science
The combination of concrete-filled steel tube (CFST) columns and reinforced concrete flat slabs provides a suitable structural solution that can be used to replace traditional structures in high-rise buildings.

Recent research and development in semi-rigid composite joints with precast hollowcore slabs [PDF]

open access: yes, 2008
Composite structure incorporating steel beams and precast hollowcore slabs is a recently developed composite floor system for building structures. This form of composite construction is so far limited to simple beam-column connections.

Multimodal Multiorgan‐on‐a‐Chip Platform for Probing Liver‐Tumor Interactions and Advancing Prodrug Screening

open access: yesAdvanced Science, EarlyView.
This work introduces a multimodal multi‐OoC platform that overcomes current limitations in liver‐tumor interaction studies and prodrug screening. By integrating dynamic microfluidic circuits, electrochemical sensing, and mass analysis, this platform enables non‐invasive, longitudinal monitoring of drug metabolism and hepatotoxicity, offering a ...

Punching shear behavior of thick reinforced concrete slabs according to Strut-and-Tie model

open access: yesBudownictwo i Architektura, 2014
The punching shear behavior of thick reinforced concrete slabs was analyzed in this paper by using strut-and-tie model (S-T). Calculating procedures were compared to our own experimental test results.

Openings effects on the structural behavior of interior voided slab-column connections: An experimental study

open access: yesCase Studies in Construction Materials, 2023
This paper studied the openings' influences on the structural responses of interior voided slab-column connections. Seven specimens were constructed with square slabs measuring 1100 × 1100 × 100 mm and contained voids distributed throughout their entire ...

Resonant line transfer in a fog: Using Lyman-alpha to probe tiny structures in atomic gas

open access: yes, 2017
Motivated by observational and theoretical work which both suggest very small scale ($\lesssim 1\,$pc) structure in the circum-galactic medium of galaxies and in other environments, we study Lyman-$\alpha$ (Ly$\alpha$) radiative transfer in an extremely ...
