Sol–Gel Derived Polymer Precursors for Stereolithography of ZrC

open access: yesAdvanced Engineering Materials, EarlyView.
ZrC is a critical material target for extreme temperature conditions. This report describes a protocol for preparing ZrC ceramics via stereolithography and examines the impact of the polymer matrix on carbothermal reduction and mechanical stability of 3D printed ZrC.

Failure Probability-Based Optimal Seismic Design of Reinforced Concrete Structures Using Genetic Algorithms

open access: yesInfrastructures
Artificial intelligence (AI) has enabled several optimization techniques for structural design, including machine learning, evolutionary algorithms, as in the case of genetic algorithms, reinforced learning, deep learning, etc. Although the use of AI for

Upgrading the seismic capacity of existing RC buildings using buckling restrained braces

open access: yesAlexandria Engineering Journal, 2017
Many existing RC buildings do not meet the lateral strength requirements of current seismic codes and are vulnerable to significant damage or collapse in the event of future earthquakes.

Seismic assessment of rc structures with infill masonry panels in Nepal: sensitivity analysis [PDF]

open access: yes, 2014
Reinforced concrete (RC) buildings in Nepal are constructed as RC frames with masonry infill panels. These structures exhibit a highly non-linear inelastic behaviour resulting from the interaction between the masonry infill panels and the surrounding ...

Perforated Shear Panels for Seismic Rehabilitation of Existing Reinforced Concrete Buildings [PDF]

open access: yes, 2015
In the field of the seismic protection of buildings, the use of steel plate shear walls (SPSWs) may be particularly appropriate for the intervention of seismic retrofitting of existing reinforced concrete (RC) buildings designed for gravity loads only ...

Exploring Dipolar Dynamics and Ionic Transport in Metal‐Organic Frameworks: Experimental and Theoretical Insights

open access: yesAdvanced Functional Materials, EarlyView.
In this study, the interplay of dipolar dynamics and ionic charge transport in MOF compounds is investigated. Synthesizing the novel structure CFA‐25 with integrated freely rotating dipolar groups, local and macroscopic effects, including interactions with Cs cations are explored.

Comparison between seismic vulnerability models and experimental dynamic properties of existing buildings in France [PDF]

open access: yes, 2018
Elastic fundamental frequency is a key-parameter of simplified seismic design and vulnerability assessment methods. Empirical relationships exist in codes to estimate this frequency but they miss experimental data to validate them accounting for national

Seismic damage and fragility of RC buildings. [PDF]

open access: yes, 2023
Seismic actions cannot be predicted in time, location or intensity. Serious earthquake actions can cause the occurrence of different levels of damage of the elements and the structure as a whole, which can even lead to their collapse. The methods for evaluation of seismic performance of structures are discussed in this paper and the focus of the paper ...

Printed Integrated Logic Circuits Based on Chitosan‐Gated Organic Transistors for Future Edible Systems

open access: yesAdvanced Functional Materials, EarlyView.
Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...
