Fragility analysis of underground large-scale frame structures considering seismic effects of vertical earthquakes

Yantu gongcheng xuebao, 2023
The increase dynamic analysis (IDA) curves of seismic responses of the underground large-scale frame structure (ULSFS) are investigated during the single horizontal earthquakes and horizontal-vertical earthquakes, respectively. The influence mechanism of

Machine learning for gravitational-wave detection: surrogate Wiener filtering for the prediction and optimized cancellation of Newtonian noise at Virgo

, 2020
The cancellation of noise from terrestrial gravity fluctuations, also known as Newtonian noise (NN), in gravitational-wave detectors is a formidable challenge. Gravity fluctuations result from density perturbations associated with environmental fields, e.

Distributed passive actuation schemes for seismic protection of multibuilding systems [PDF]

, 2020
In this paper, we investigate the design of distributed damping systems (DDSs) for the overall seismic protection of multiple adjacent buildings. The considered DDSs contain interstory dampers implemented inside the buildings and also interbuilding ...

Application of BIM Technology in the Seismic Performance of “Wood Weaving” Structure of Wooden Arcade Bridges

Shock and Vibration, 2022
The wood arch bridge has good seismic performance, and the “wood weaving” of its arch system is closely related. Wood weaving has the isolation function similar to that of rubber bearing isolation layer under earthquake, which is the key to ensuring good

Long term study of the seismic environment at LIGO

, 2004
The LIGO experiment aims to detect and study gravitational waves using ground based laser interferometry. A critical factor to the performance of the interferometers, and a major consideration in the design of possible future upgrades, is isolation of ...

Improving seismic performance

Bulletin of the New Zealand Society for Earthquake Engineering, 2008
Structural engineers typically improve the seismic performance of deficient structures by adding strengthening elements to the structural system, which also add stiffness to the structure. However, as performance based design becomes more common practice, the focus is on the total performance of not only the structural system but the building ...

Performance-Based Seismic Design for buildings

Structural Mechanics of Engineering Constructions and Buildings, 2020
Structures are designed using current seismic design codes which are mostly based on Force-Based Design approach. The aim of the work is to implement the Performance-Based Seismic Design (PBSD) approach in concrete buildings. PBSD, which is a new concept
