Singular Spectrum Analysis for Modal Estimation from Stationary Response Only
Sensors, 2022 Conventional experimental modal analysis uses excitation and response information to estimate the frequency response function. However, many engineering structures face excitation signals that are difficult to measure, so output-only modal estimation is ...

A Computationally Efficient Ground-Motion Selection Algorithm for Matching a Target Response Spectrum Mean and Variance [PDF]
, 2011 Dynamic structural analysis often requires the selection of input ground motions with a target mean response spectrum. The variance of the target response spectrum is usually ignored or accounted for in an ad hoc manner, which can bias the structural ...

Earthquake design for controlled structures [PDF]
Fracture and Structural Integrity, 2017 An alternative design philosophy, for structures equipped with control devices, capable to resist an expected earthquake while remaining in the elastic range, is described. The idea is that a portion of the earthquake loading is undertaken by the control

Investigation of the angle formed in irregular structures on their seismic behavior
Journal of Materials and Engineering Structures, 2023 The design of structures with re-entrant angle is often the consequence of the functional, architectural or urbanistic requirement. With any form building, the engineer has full responsibility to ensure the safety of the users and the structure in the ...
