Nonlinear Analysis and Optimization of Recycled Aggregate Concrete Cross-Sections Based on Restoring Force Models

Buildings, Journal Year: 2025, Volume and Issue: 15(2), P. 173 - 173

Published: Jan. 9, 2025

This research presents a simplified approach using uniaxial restoring force model to analyze the seismic response of recycled aggregate concrete (RAC) frames. Nonlinear simulations were conducted explore how factors like axial compression ratio, reinforcement and cross-sectional geometry affect ductility performance RAC sections. The findings reveal that reduction in ratio from 0.60 0.57 results 15% increase ductility, while higher leads 20% enhancement. In addition, rectangular sections found be more sensitive variations material strength than square sections, offering key insights for structural optimization. method proposed here also enhances computational efficiency by minimizing resource consumption improving convergence nonlinear iterative procedures. These provide theoretical foundation optimizing design evaluation structures, promoting their broader application engineering practice.

Identification of Inequities in Green Visibility and Ways to Increase Greenery in Neighborhoods: A Case Study of Wuhan, China

Applied Sciences, Journal Year: 2025, Volume and Issue: 15(2), P. 742 - 742

Published: Jan. 13, 2025

The rapid increase in urban population density driven by development has intensified inequity green space distribution. Identifying the causes of changes equity and developing strategies to improve greening are crucial for optimizing resource allocation alleviating social inequalities. However, long-term spatio-temporal evolution visibility remains underexplored. This study utilized “Time Machine” feature capture street view images from 2014, 2017, 2021, analyzing its across residential communities Wuhan. Deep learning techniques statistical methods, including Gini coefficient location quotient (LQ), were employed assess distribution spatial street-level greenery. results showed that overall Wuhan increased 4.18% between 2014 2021. this improvement did not translate into better equity, as consistently ranged 0.4 0.5. Among seven municipal districts, only Jiang’an District demonstrated relatively equitable 2017 Despite a gradual reduction disparities visibility, mismatch persisted UGS growth distribution, leading uneven patterns equity. explores factors driving inequities proposes enhance greening. Key recommendations include integrating evaluation framework planning guide fair allocation, prioritizing greenery low-income neighborhoods, reducing hardscapes support planting maintenance tall canopy trees. These measures aim accessible visible resources promote access communities.

Impact of Spatial Configuration of Bioretention Cells on Catchment Hydrological Performance Under Extreme Rainfall Conditions with Different Stormwater Flow Paths

Water, Journal Year: 2025, Volume and Issue: 17(2), P. 233 - 233

Published: Jan. 16, 2025

Bioretention cells (BCs) are widely used to manage urban runoff due their positive impact on control. Current research primarily focuses optimizing the internal structural design of bioretention cells, while studies interactions between spatial configuration, topography, and land use types limited. This study employs Storm Water Management Model (SWMM) uses extreme rainfall analyze influence typical stormwater flow paths, determined by various as well configurations catchment hydrological performance. The results show following: (1) Different paths significantly affect performance, with series-type pathways performing best. (2) configuration influences Decentralized BCs under showed better performance for reducing total outflow peak runoff, reduction rates increasing 7.1% 8.8%, centralized delayed times. (3) Stormwater BC efficiency in a path recommended priority use. provides novel perspective arrangement management, thereby contributing flood risk mitigation.
