Numerical model to simulate the non-linear shear behaviour of RC elements [PDF]

, 2009
Seismic assessment of RC structures requires realistic and simple analytical models. In this paper is presented the model proposed and implemented in the program PORANL, to represent the RC buildings behaviour under severe earthquake loading.

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

Advanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

A combined local damage index for seismic assessment of existing RC structures [PDF]

, 2013
A new local damage index for existing reinforced concrete (RC) structures is introduced, wherein deterioration caused by all deformation mechanisms (flexure, shear, anchorage slip) is treated separately for each mechanism.

Micro Elastofluidics for Tuneable Droplet Merging

Advanced Materials Technologies, EarlyView.
This technical paper provides a proof of concept of fully flexible and stretchable microfluidic technology for tuneable droplet mixing and merging. The phenomenon is justified through theoretical, numerical and experimental studies. ABSTRACT Droplet microfluidics enables precise handling of discrete fluid volumes at the microscale, with broad ...

Seismic Evaluation and Retrofit of Reinforced Concrete Buildings with Masonry Infills Based on Material Strain Limit Approach

Shock and Vibration, 2021
The seismic evaluation and retrofit of reinforced concrete (RC) structures considering masonry infills is the correct methodology because the infill walls are an essential part of RC structures and increase the stiffness and strength of structures in ...

Modified Gutenberg-Richter coefficient for damage evaluation in reinforced concrete structures subjected to seismic simulations on a shaking table [PDF]

, 2014
This paper presents analysis and discussion of the b- and ib-values calculated from the acoustic emission (AE) signals recorded during dynamic shake-table tests conducted on a reinforced concrete (RC) frame subjected to several uniaxial seismic ...

SEISMIC PERFORMANCE OF RC FRAME RETROFITTED BY CES PORTAL FRAME

Journal of Structural and Construction Engineering (Transactions of AIJ), 2009
This research deals with a seismic retrofitting technique of installing CES portal frames to an existing RC frame building. One of characteristics in the retrofitting technique is to employ the precast construction method that precast CES members are connected at the middle of the beam and columns of the portal frame.

Non-linear Behaviour of Infilled RC Frame

IOP Conference Series: Materials Science and Engineering, 2020
Abstract The reinforced concrete (RC) infilled frame is very common in exercise. In general, only infill weight is considered in the design of the RC infilled frame, and the strength of masonry is ignored. However, the prominence of masonry infill on the seismic behaviour is highlighted during past earthquakes.

Radiative Cooling by Green(er) Solvents‐Upcycled Polyvinyl Chloride From Drug Blisters Waste

Advanced Optical Materials, EarlyView.
This study explores upcycling poly(vinyl chloride) (PVC) from used pharmaceutical blisters into sustainable radiative cooling materials. Using solvent separation and membrane fabrication, PVC was converted into white membranes paired with aluminum foil.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.
