Structural capacity of precast concrete walls with openings: A parametric study on connection types and reinforcement ratios

open access: yesStructural Concrete, EarlyView.
Abstract The structural role of precast concrete walls with openings is often overlooked in design practice due to concerns about reduced stiffness, stress concentration, cracking around openings, and potential unexpected failure modes under seismic loading.

Topological Structure of the Admissible Design Space of Closure Maps

open access: yes
P81 established a sucient geometric criterion for a single closure map g to becollapse-determining: the scalar eld ϕg = LXg V must be uniformly positive onHθ \ C and vanish on C. The present paper lifts this characterisation to the levelof the full admissible function space of closure maps, studying the topological1structure of Gadm ⊆ Γ

The influence of secondary reinforcement on a strut‐and‐tie model for the design of reinforced concrete corbels

open access: yesStructural Concrete, EarlyView.
Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

Fault‐Tolerant Fuzzy Boundary Control for Nonlinear Distributed Parameter Systems Under Limited Measurements and Markovian Failures

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper proposes a boundary control method for nonlinear distributed parameter systems (DPSs) with limited boundary measurements (BMs), as typically encountered in networked cyber‐physical processes with spatially distributed dynamics such as thermal and biomedical diffusion systems.

A unified analytical framework for Mössbauer synchrotron sources

open access: yesJournal of Synchrotron Radiation, EarlyView.
We present a unified analytical framework for Mössbauer synchrotron and X‐ray free‐electron laser sources that provides exact, rotationally invariant expressions for resonance energies and transition probabilities in mixed magnetic dipole–electric quadrupole interactions without Hamiltonian diagonalization.
