Space-frame structures are extensively used in modern architecture and engineering due to their high load-bearing efficiency, lightweight nature, suitability for large-span applications. This study assesses seismic response through nonlinear static time-history analyses using finite element modeling ABAQUS. Various configurations with different spans, heights, column arrangements were analyzed under loads. The modification factor (R) was evaluated concerning ductility-based reduction, overstrength, allowable stress factors, ranging from 2.6 3.8. Results indicate that structural ductility plays a crucial role determining the Response factor, notable variations across configurations. Increasing number of columns improves this whereas low-story models exhibit reduced ductile behavior. Time-history analysis reveals base shear values remain within similar range but sensitive frequency content. Additionally, increasing story height leads significant rise maximum roof displacement, highlighting influence on performance stability dynamic conditions.

A Communication-Efficient Federated Learning Framework for Sustainable Development Using Lemurs Optimizer

Algorithms, Год журнала: 2024, Номер 17(4), С. 160 - 160

Опубликована: Апрель 15, 2024

The pressing need for sustainable development solutions necessitates innovative data-driven tools. Machine learning (ML) offers significant potential, but faces challenges in centralized approaches, particularly concerning data privacy and resource constraints geographically dispersed settings. Federated (FL) emerges as a transformative paradigm by decentralizing ML training to edge devices. However, communication bottlenecks hinder its scalability sustainability. This paper introduces an FL framework that enhances efficiency. proposed addresses the bottleneck harnessing power of Lemurs optimizer (LO), nature-inspired metaheuristic algorithm. Inspired cooperative foraging behavior lemurs, LO strategically selects most relevant model updates communication, significantly reducing overhead. was rigorously evaluated on CIFAR-10, MNIST, rice leaf disease, waste recycling plant datasets representing various areas development. Experimental results demonstrate reduces overhead over 15% average compared baseline while maintaining high accuracy. breakthrough extends applicability resource-constrained environments, paving way more scalable real-world initiatives.

Concurrent multiscale topology optimization for size-dependent structures incorporating multiple-phase materials

Results in Engineering, Год журнала: 2024, Номер 23, С. 102491 - 102491

Опубликована: Июль 2, 2024

The significant progress in additive manufacturing has resulted the development of well-engineered microstructures with innovative topological configurations, showcasing exceptional performance across diverse fields. Topology optimization is widely recognized as an advanced design tool that provides engineers new insights for creating lightweight structures. As integration devices continue to trend towards miniaturization, size effect small-scale structures remains a persistent challenge. absence characteristic parameters describe this hinders proper explanation through traditional multiscale topology based on classical mechanics. Therefore, we propose size-dependent framework concurrent involving multiple-phase materials. modified couple stress theory proposed account numerical findings suggest significantly influenced by ratio elastic modulus, volume fraction, and width-to-length representative element its approaches length material. These results highlight importance considering effects provide valuable researchers field.
