Perforation Enhances Sound Insulation in Plate Lattice Metamaterials
Small, EarlyView.Herein, perforations are engineered into face‐centered cubic plate lattice metamaterials to convert normally detrimental openings into acoustically active features. Experiments, finite‐element analyses, and a reduced‐order transfer‐matrix model show that selected perforation geometries activate Helmholtz‐like and cavity‐mediated resonances, enhancing ...

Software: Practice and Experience, EarlyView.ABSTRACT Background Application programming interfaces (APIs) help distributed systems and microservices to expose their functionalities and serve as a means for communication among them. Understandability and readability of APIs are important for effectively comprehending and using APIs.

Experimental results and limit load analysis by the strut-and-tie method (STM) in deep beams with notches and openings [PDF]
Revista IBRACON de Estruturas e MateriaisThis article presents experimental results of eight non-aligned, non-geometrically symmetrical deep beams with notches and openings. The variables considered in the study were the presence of web reinforcement, and the geometry of the deep beams.

Analysis and design of reinforced concrete deep beams using the stress fields method
Acta Scientiarum: Technology, 2017 Bernoulli's hypothesis facilitates the understanding of some structural elements. However, this hypothesis cannot be applied for some special regions, denominated `D regions´ or `Discontinuity regions´.

Numerical analyses of two-pile caps considering lateral friction between the piles and soil
Revista IBRACON de Estruturas e Materiais, 2021 : Pile caps are structural elements used to transfer loads from the superstructure to a group of piles. The design of caps is normally based on analytical formulations, considering the strut and tie method. Through the advance of computational technology,

Reverse engineering strut‐and‐tie models for assessing reinforced concrete structures
Structural Concrete, EarlyView.Abstract Strut‐and‐tie models enable the design of reinforced concrete structures with static or geometrical discontinuities, providing interpretability and control over the load path. These models are valuable for designing discontinuity regions of new structures and for validating nonlinear finite‐element analysis results. However, developing a strut‐

Analysis of the nodal stresses in pile caps
Revista IBRACON de Estruturas e Materiais, 2018 Pile caps can be dimensioned using, preferably, plastic models (strut-and-tie) and models based on the flexion theory. In order to analyze the behavior of the stresses in the lower and upper nodal regions of the cap, a theoretical analysis of the ...

Structural 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 ...
