This paper aims to quantify the evolution of damage in masonry walls under induced seismicity. A damage index equation, which is a function of the evolution of shear slippage and opening of the mortar joints, as well as of the drift ratio of masonry walls, was proposed herein. Initially, a dataset of …

Frailty and Physical Therapy講演要旨 （Abstract）The speed of ageing differs from country to country, but ageing is worldwide happening more quickly than in the past. We live in a dangerous world and all kinds of negative influences like stress or poor nutrition causes random molecular damage with an accumulation …

This paper aims to quantify the cumulative damage of unreinforced masonry (URM) subjected to induced seismicity. A numerical model based on discrete element method (DEM) has been develop and was able to represented masonry wall panels with and without openings; which are common typologies of domestic …

The majority of houses in the Groningen gas field region, the largest in Europe, consist of unreinforced masonry material. Because of their particular characteristics (cavity walls of different material, large openings, limited bearing walls in one direction, etc.) these houses are exceptionally vulnerable …

Ever since the recognition of the causality between earthquakes in the Region Groningen, gas production and the ensuing damage to houses and buildings in that area, government faces big challenges in policy-making. On the one hand liability for damages must result in fast and effective repair of houses …

In the present paper a damage model for single crystal Ni-base superalloys is proposed that integrates time-dependent and cyclic damage into a generally applicable time-incremental damage rule. A criterion based on the Orowan stress is introduced to detect slip reversal on the microscopic level and the cyclic …
