Study on Breaking Concrete Structures by Pulse Power Technology

Buildings, 2022
Using pulse power technology to break concrete structures can reduce environmental pollution, save energy, and increase safety and reliability. The whole process of concrete beam subjected to shock wave generated by pulse power discharge was simulated ...

Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites

Advanced Functional Materials, EarlyView.
We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Tension stiffening effects in reinforced concrete members [PDF]

, 1985
This thesis is in two parts which are related by the common theme of tension stiffening. Part I develops the concept of a stress-strain envelope to model the behaviour of the concrete in tension below the neutral axis of a reinforced concrete beam.

Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, EarlyView.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

A case study of flexural performance of reinforced concrete beams bonded with steel plates with different thickness

Journal of Materials Research and Technology, 2019
This study investigates the flexural behavior of four reinforced concrete beams. The beams were composed by adding steel plates which have different thickness (2, 3, and 5 mm) in the tension zone to invention out the consequence of the altered plate ...

Comparative Study of Reinforced Concrete Beams in School Buildings Using Prestressed Concrete Beams

Journal of Civil Engineering and Planning, 2022
Building construction in Indonesia generally uses concrete. The concrete used for building structures, such as beams, generally utilizes reinforced concrete. It is very rare to see the use of prestressed concrete for building structures such as beams, especially in Batam City.

Non-destructive evaluation of concrete using a capacitive imaging technique : preliminary modelling and experiments [PDF]

, 2010
This paper describes the application of capacitive imaging to the inspection of concrete. A two-dimensional finite-element method was employed to model the electric field distribution from capacitive imaging probe, and how it interacts with concrete ...
