Accounting for amplitude of excitation in model updating through a hierarchical Bayesian approach: Application to a two-story reinforced concrete building
(2019)Calibrated linear equivalent models of civil structures are often used for response prediction and performance assessment. However, these models are only valid for a narrow range of excitation level for which these models ... -
Accounting for modeling errors and inherent structural variability through a hierarchical bayesian model updating approach: An overview
(2020)Mechanics-based dynamic models are commonly used in the design and performance assessment of structural systems, and their accuracy can be improved by integrating models with measured data. This paper provides an overview ... -
Axial strength of FRP-confined reinforced concrete columns
(2016)The enhancement of the axial strength of plain concrete columns wrapped with fibre-reinforced polymer (FRP) fabrics has been extensively investigated, both analytically and experimentally. Respective research on reinforced ... -
Bayesian optimal estimation for output-only nonlinear system and damage identification of civil structures

The effect of cracking on the response and design of diaphragm walls and adjacent buildings
(2015)The development of the bending moment corresponding to the maximum tensile stress the concrete accommodated (relatively low with reference to the capacity of the wall) produces cracking initiation. Despite the fact that ... -
Experimental and numerical study of the behaviour of high dissipation metallic devices for the strengthening of existing structures
(2011)The use of steel bracing systems for the strengthening of existing reinforced concrete (RC) frames may lead to increase of both strength and stiffness. However, in most of the cases the main target is the increase of the ... -

Ground-borne noise and vibration transmitted from subway networks to a typical Athenian multi-storey reinforced concrete building
(2016)The transmission of ground-borne vibrations from subway rail transit systems in a building is governed by the soil-foundation interaction, the reduction of vibration level between floors, and the amplification due to ... -
Ground-borne noise and vibration transmitted from subway networks to multi-storey reinforced concrete buildings
(2018)During the operation of urban subway rail transit systems, vibrations are generated that transmitted through the soil, induce vibrations in nearby buildings. The transmission of ground-borne vibrations from subway rail ... -
