Moment–curvature damage model for bridges subjected to seismic loads [PDF]
Computer Methods in Applied Mechanics and Engineering, 2006 The evaluation of the damage caused by horizontal loads, such as seismic action, to existing bridges has received an important attention in recent years, because it is the first step towards reducing casualties and economic losses. In damage detection and evaluation, the application of simple and reliable models has been prioritized, because ...

Shock and Vibration, 2021 The seismic response of reinforced concrete (RC) plan-asymmetric structures is significantly influenced by the input angle of seismic ground motions. Hence, it is challenging to assess the performance of plan-asymmetric structures.

Plastic–damage seismic model for reinforced concrete frames [PDF]
Computers & Structures, 2008 A plastic–damage model for reinforced concrete frames is developed in this article, based on the classical plastic model and the continuum damage model. The plastic–damage constitutive law is implemented into a beam model for framed structures, in which these are described by elastic beams and columns with two inelastic hinges at their ends.

Seismic evaluation of concrete dams via continuum damage models [PDF]
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1996 AbstractIn this paper a general methodology for the analysis of large concrete dams subjected to seismic excitation is outlined. It is valid both for gravity dams (2D representation) and arch dams (3D representation). The method allows for non‐linear material behaviour of the dam, ‘transparent fictitious boundaries’ for dealing properly with in‐coming ...

Seismic Damage Behaviour of Aeolian Sand Concrete Columns with I-Shaped Structural Steel [PDF]
Archives of Civil Engineering, 2020 To promote the application of aeolian sand resources for steel-concrete composite structures, an aeolian sand reinforced concrete column with I-shaped structural steel is proposed in this study. Four specimens are designed and manufactured with different

Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]
, 2014 Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.

An efficient methodology to estimate probabilistic seismic damage curves [PDF]
, 2019 The incremental dynamic analysis (IDA) is a powerful methodology that can be easily extended for calculating probabilistic seismic damage curves. These curves are metadata to assess the seismic risk of structures.

A Comparative Test Study on the Seismic Damage Sustained by Frame-Core Tube Structures
Advances in Civil Engineering, 2019 The overall damage sustained by a structure can be controlled in the current damage-based seismic design, but the rationality of the relationship among the damage states of the components in the structure and the influences of those states on the overall

Simplified Estimation of Economic Seismic Risk for Buildings [PDF]
, 2004 A seismic risk assessment is often performed on behalf of a buyer of commercial buildings in seismically active regions. One outcome of the assessment is that a probable maximum loss (PML) is computed.
