Study on the Bending Performance of High-Strength and High-Ductility CRE-Reinforced Concrete Beams

open access: yesBuildings, 2023
Constant resistance energy (CRE) steel reinforcement has a yield strength of up to 750 MPa and an ultimate elongation of more than 20%. CRE reinforcement overcomes the contradiction between high yield strength and high uniform elongation of ordinary high-

Variational methods for phononic calculations [PDF]

open access: yesWave Motion, 2016
Three fundamental variational principles used for solving elastodynamic eigenvalue problems are studied within the context of elastic wave propagation in periodic composites (phononics). We study the convergence of the eigenvalue problems resulting from the displacement Rayleigh quotient, the stress Rayleigh quotient and the mixed quotient.

On the Methodology for Calculating the Economic Efficiency of Energy Storage Systems

open access: yesИзвестия высших учебных заведений и энергетических объединенний СНГ: Энергетика
Due to the growth of “green” energy, the need to regulate the load on large power systems, and the development of electric transport, electricity storage systems (ESS) are increasingly, being used in the world. Conceptual documents have been developed in

Frequency stability control method considering limited EDCPS

open access: yesThe Journal of Engineering, 2019
Aiming at the problem of frequency stability of the asynchronous AC/DC hybrid power grid, a prediction model of post-disturbance steady frequency is proposed, which considers the emergency DC power support (EDCPS) and the frequency response of AC grids ...

The Effect of the Bearing Width on the Buckling Capacity of Partially Loaded CLT Member

open access: yesBuildings, 2022
The calculation method for buckling capacity of cross-laminated timber (CLT) under axial load with one-way members has been investigated and incorporated into design codes worldwide. However, the load may only be applied to a part of the CLT members.
