Effect of vehicle-bridge interaction on nonlinear seismic performance of bridge under strong earthquakes

High-Speed Railway
Railway bridges are continuously loaded by railway trains; therefore, it is important to understand the nonlinear seismic response of the Vehicle-Bridge Interaction (VBI) system under strong earthquakes.

Characterizing the Seismic Behavior of Guyed Masts

Journal of Earthquake Engineering, 2008
Guyed masts are specialised structures whose seismic performance is poorly understood. In this article, four existing guyed masts in the UK with heights ranging from 99–312 m are analyzed under various seismic loading conditions. The results are used to: gain an understanding of the magnitude and distribution of forces developed in guyed masts during ...

Seismic Analysis of Historic Masonry Buildings: The Vicarious Palace in Pescia (Italy)

Buildings, 2012
Recent Italian earthquakes have underlined the need for wide monitoring and safety assessment of architectonical heritage. This has emerged also from requirements of the new Italian Technical Recommendations for buildings.

Seismic behavior of slender reinforced concrete walls

Engineering Structures, 2014
Abstract Residential reinforced concrete buildings performed well during the 2010 Mw 8.8 Maule, Chile earthquake. However, brittle damage was observed in reinforced concrete structural walls. The most frequent observed damage in such walls was crushing of concrete due to flexural-compressive interaction, buckling and fracture of longitudinal ...

Out‐of‐plane reinforcement of masonry walls using joint-embedded steel cables [PDF]

, 2020
The out-of-plane mechanism (rocking) of walls often causes fatalities and collapses of historic buildings during earthquakes. This paper addresses the problem of assessing the seismic resistance of walls subjected to out-of-plane bending, before and ...

A Bottom‐Up Design Framework for Multifunctional Lattice Metamaterials

Advanced Science, EarlyView.
This study introduces a generative AI framework for designing multifunctional lattice metamaterials. The method combines 3D Gaussian voxel generation with deep learning, enabling greater design freedom and structural performance. The optimized lattice metamaterials achieve enhanced energy absorption by 40–200% compared to conventional structures and ...

NEW SEISMIC SOURCE ZONE MODEL FOR PORTUGAL AND AZORES [PDF]

, 2010
The development of seismogenic source models is one of the first steps in seismic hazard assessment. In seismic hazard terminology, seismic source zones (SSZ) are polygons (or volumes) that delineate areas with homogeneous characteristics of seismicity ...
