Behavior predictions of deep beams with short straight bar anchorages using strut-and-tie models and nonlinear analysis

Revista IBRACON de Estruturas e Materiais
This paper investigates the laboratory test results of 12 deep beams available in the literature, where the longitudinal reinforcement was anchored into the support using short straight bar anchorages.

Generation of Strut-and-Tie Models and Stress Fields for Structural Concrete [PDF]

Structures Congress 2019, 2019
Strut-and-tie models are principally the discretized stress fields, which simplify the dimensioning and detailing of reinforced concrete members. The computational generation of stress fields currently relies on finite element analysis or optimization methods.

Evaluating structural resistance and updating modeling uncertainties through testing

Structural Concrete, EarlyView.
Abstract The aging of infrastructure necessitates a robust and rational methodology for the assessment of existing structures. Design codes provide general models which cover different design scenarios and are thus overly conservative. Also, such design approaches lack field data and, if applied directly to existing works, often lead to unnecessarily ...

Optimized Design of Anchor Plates for 2200 MPa-Class Prestressing Anchorage Zones

Buildings
The strength of prestressed steel strands has developed towards high strength, increasing from 1860 MPa to over 2200 MPa. The stress in the prestressed anchorage zone is more concentrated and complex, and the anchor plates for dispersed loads need to be ...

Reliability analysis of strut-and-tie models for the design of deep beams according to NBR 6118 (2023) [PDF]

Revista IBRACON de Estruturas e Materiais
The strut-and-tie method (STM) applied in the structural design of deep beams is a semi-probabilistic method, that does not take directly into account both the uncertainties associated with the variables involved and those inherent in the calculation ...

Localized tension characterization of reinforced concrete flexural members using surface bonded distributed fiber optic sensors

Structural Concrete, EarlyView.
Abstract Structural monitoring and assessment can be used to ensure the long‐term performance of structures and inform when maintenance is required by accounting for the degradation of material properties. A key force‐resisting mechanism in reinforced concrete that must be considered as part of an assessment and that can degrade over time is tension ...

Equal before time: on the sensory suspension of accumulated time in Sichuan, China Égaux devant le temps : suspension sensorielle du temps accumulé au Sichuan (Chine)

Journal of the Royal Anthropological Institute, EarlyView.
Food and alcohol indulgence, along with tea‐drinking, gambling, and gossip, are integral to a characteristically Sichuanese ethos of ‘life enjoyment’ (xiangshou shenghuo). Beyond mere pleasure, sensory, ludic, and comic experiences temporarily strip participants of both their formal and subjective qualities.

Staging friendship: towards an anthropology of everyday geopolitics in South Asia L'amitié mise en scène : vers une anthropologie de la géopolitique du quotidien en Asie du Sud

Journal of the Royal Anthropological Institute, EarlyView.
This article studies Indian‐Bangladeshi friendship ethnographically, as a contested political imaginary, claim, and relation, from the vantage of its shared borderlands. Staging friendship, I show, is a geopolitical project that engages equally the highest echelons of the Indian and Bangladeshi states and ordinary residents of its marginalized ...

Reinforced concrete corbels strengthened with external prestressing

Revista IBRACON de Estruturas e Materiais, 2019
Reinforced concrete structures may demand, throughout their lifetime, the increase of the capacity load due to eventual changes in the load configuration. In this context, corbels could be considered structural elements which present great challenges for

Mainland diversification and recent island lineages in the reduviid genus Tapirocoris: an integrative taxonomic framework with four new species

Insect Science, EarlyView.
Using an integrative taxonomic framework that combines COI DNA barcodes, geometric morphometrics and phylogeography, we revise the assassin bug genus Tapirocoris and recover seven well‐supported species, including four newly described cryptic species.
