Seismic fragility estimates of steel diagrid structure with performance-based tests for high-rise buildings

Chengqing Liu et al.

Summary: This article investigates the application of diagrid structures in seismic performance design, and experimentally determines the bending and yield performance of steel diagrid structures, as well as the limit state values for various performance levels. The study found that in high-rise buildings, the bottom tilted columns are the first place where plastic hinging occurs.

Reflection on earthquake damage of buildings in 2015 Nepal earthquake and seismic measures for post-earthquake reconstruction

Chengqing Liu et al.

Summary: Researchers conducted a detailed investigation on earthquake damages in Nepal, proposing reinforcement measures and suggestions that focus on the load transmission path of the structure, the enclosure structure, the beam-column joints, the integrity of the structure, house site selection, and structural stiffness. The surrounding areas of door and window openings are still the most vulnerable places to be damaged and reinforcement should be strengthened in these locations.

Seismic Analysis of Isolated Continuous Bridge considering Influence of Seawater and Site Condition

Baokui Chen et al.

Summary: The study shows that seawater and muddy soil have significant effects on the seismic response of isolated continuous girder bridges, with seawater increasing the relative displacement of piers and muddy soil significantly increasing the displacement and internal forces of piers. The combined influence of muddy soil and seawater also leads to a significant increase in displacement at bridge bearings.
