CO2 Fluxes and Soil Responses to Straw and Herbicide in Peanut

Land Degradation &Development, EarlyView.
ABSTRACT Peanut cultivation plays an important agronomic role in Brazil, especially in rotation with sugarcane, promoting biological nitrogen fixation and improving soil quality. This study aimed to test the hypothesis that the combined use of sugarcane mulch, peanut cultivation, and herbicide application would affect soil CO₂ fluxes, soil chemical ...

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

Structural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

Bond‐slip modeling for reinforced concrete beam‐column joints with plain reinforcement bars: Insights from numerical validation

Structural Concrete, EarlyView.
Abstract The previous seismic events indicated the vulnerability of old reinforced concrete (RC) structures against earthquakes due to the absence of seismic detailing and capacity design specifications in such buildings. In this context, beam‐column joints (BCJ) of the existing RC structures built before the 1970s have exhibited poor structural ...

Non-linear approaches to the response of brick masonry wall to lateral loading [PDF]

, 2018
The response of brick masonry wall subjected to lateral loading is presented in this paper. Modelling and analysis of masonry seems to be complicated due to two-component material with different properties and dimensions.
