Component Seismic Damage Model for SRHSHPC Joints
Key Engineering Materials, 2009The deficiency of present damage model is generalized by studying existing references. The mechanical properties of steel reinforced high strength and high performance concrete (SRHSHPC) members under monotonic loading, including the capacity of ultimate deformation, strength, stiffness, etc. are analyzed after the different number of cycles.

A statistical damage model with implications for precursory seismicity
Acta Geophysica, 2011Acoustic emissions prior to rupture indicate precursory damage. Laboratory studies of frictional sliding on model faults feature accelerating rates of acoustic emissions prior to rupture. Precursory seismic emissions are not generally observed prior to earthquakes. To address the problem of precursory damage, we consider failure in a fiber-bundle model.

Seismic characterisation of fault damage in 3D using mechanical and seismic modelling
Marine and Petroleum Geology, 2016Abstract Although typically interpreted as 2D surfaces, faults are 3D narrow zones of highly and heterogeneously deformed rocks with petrophysical properties differing from the host rock. Fault zones have been extensively studied in outcrop, but in the subsurface they are barely explored, mainly because they are at the limit of seismic resolution and

Seismic Damage Analysis Model for RC Structures Based on Concrete Plastic Damage Model
Structures Congress 2011, 2011Firstly, a plastic-damage constitutive model for concrete complying with the laws of thermodynamics is proposed based on continuum damage mechanics theory. The damage constitutive equations, damage evolution equations and plastic deformation of concrete are derived. Secondly, Fiber damage analysis model(FDAM) for RC beam-column member is established by

Dynamic rupture and seismic radiation in a damage-breakage rheology model
Pure and Applied Geophysics, 2018<p>We present simulations of dynamic ruptures in a continuum damage-breakage rheological model and waves radiated by the ruptures observed in the far field. The model combines aspects of a continuum viscoelastic damage framework for brittle solids with a continuum breakage mechanics for granular flow.

Rapid Diagnostic Model of Road Lifeline Seismic Damage Based on Seismic Intensity
Access Management Theories and Practices, 2015Earthquake is one of the serious geological disasters in China, it would cause varying degrees of damage to road lifeline. Due to the difficulty of quickly getting the damage information of road lifeline after earthquake, it has a great impact on the rescue work.

Structure‐to‐structure seismic damage correlation model
Earthquake Engineering & Structural DynamicsAbstractStrong earthquake disasters can cause noticeable damage correlations among regional buildings with similar mechanical properties, termed structure‐to‐structure seismic damage correlation, which has a pronounced impact on the regional seismic risk assessment and therefore needs to be properly quantified. This study first introduces a time‐domain

Estimation of the seismic demand model for different damage levels
Engineering Structures, 2019Abstract The estimation of seismic demand that connects the ground motion intensity measure and the damage measure of structures is one of the most important components in the performance-based design. The random nature of earthquake ground motion with great uncertainties in structural properties has posed challenges before this estimation.

Empirical predictive model for seismic damage of historical churches
Bulletin of Earthquake Engineering, 2020Generally, strong seismic events cause serious damage to cultural heritage, especially in ancient churches characterized by a high vulnerability due to the intrinsic peculiarities of their structural systems which are not able to develop efficient resisting mechanisms.

A DAMAGE MODEL FOR THE ANALYSIS OF THE SEISMIC RESPONSE OF MONUMENTAL BUILDINGS
Journal of Earthquake Engineering, 2005In this paper the Author proposes a damage model for the analysis of masonry plates and shells, which is based on an improvement of a previous constitutive model. The modifications introduced, connected to the head joint damage, allow us to study the influence of masonry texture on the damage modes once the mechanical characteristics of the elements ...
