For "I-shaped," "L-shaped," "T-shaped," and "cross-shaped" walls, the structures are classified into three categories—ends, webs, and connections—based on the constrained zones. A unified axial load-bearing capacity formula for concrete-filled steel tube (CFST) bundle short-limb shear walls is deriv…
The geometric shape of the non-obstructive particle damper (NOPD) cavity significantly alters the pressure distribution characteristics between particle layers, thereby affecting its vibration suppression performance. The dynamic characteristics of a conical cavity NOPD were analyzed using the discr…
With the development of renewable energy, the voltage support strength of multi-infeed renewable energy systems is gradually decreasing, necessitating effective strength assessment methods. If all equipment is assumed to operate at rated operating points, existing power grid strength indicators and …
The dynamic characteristics of new energy power systems are complex, featuring numerous stability analysis methods and stability criteria. Different stability methods/criteria correspond to different physical interpretations and applicable scopes, making it currently difficult to theoretically addre…
The first part of this paper proposes qualitative principles and quantitative evaluation metrics for assessing the adaptability of stability analysis methods/criteria from three perspectives: stability equivalence, nominality, and robustness. The second part further examines typical equipment includ…
Exergy is an indicator for measuring energy quality, which profoundly reveals the essence of work capability loss during energy transfer processes. To investigate the dynamic evolution mechanism of ? in time-varying energy networks, this paper formulates the constitutive relations among physical qua…
