Statistical system identification of structures using ARMA models
The present study focuses on the estimation of the modal properties, i.e., natural modal frequencies, modal damping ratios, and mode shapes, of a structural system under ambient vibration based on the response data of the ...
Modeling of non-ductile R/C flat-plate buildings subjected to seismic loading (earthquake loading)
Nonlinear dynamic analysis of non-ductile flat-plate buildings requires a suitable hysteretic model and an equivalent frame approach which appropriately models the lateral stiffness of the buildings. Based on the test ...
Analysis of laser-welded sandwich plates
A comprehensive study is made of two types of sandwich plates under normal loads applied to their faces. The plates are composed of two plate facings separated by, and laser-welded to, either corrugated sheets or standard ...
Response of earth dams in semi-elliptical canyons to oblique SH waves
Two analytical closed-form solutions are developed for steady-state lateral response of earth and rockfill dams built in semi-elliptical canyons. In the first model, the canyon is assumed to be rigid, while the dam is ...
Dynamic soil pressures on rigidly and elastically supported embedded vaults
A comprehensive study is made of an approximate model for the computation of the dynamic pressures and associated forces induced by ground shaking on rigid embedded vaults (2, 10). For rigidly supported vaults, it is shown ...
