Passive energy dissipation systems are one of the most resilient solutions to mitigate the seismic risk of structures. In case of strong motions, they can confine the eventual damages into easily replaceable anti-seismic devices.

PEER Testbed Study on a Laboratory Building: Exercising Seismic Performance Assessment [PDF]
From 2002 to 2004 (years five and six of a ten-year funding cycle), the PEER Center organized the majority of its research around six testbeds. Two buildings and two bridges, a campus, and a transportation network were selected as case studies to ...

When does the story end? Presence, the present and ‘the contemporary world’
Abstract We write and read ethnography in the wake of time passing: a fact that has long thrown up a host of epistemological and ethical issues for the doing of anthropology. In this essay I revisit this classic problem—the problem of the ethnographic present—asking what happens when we rethink the relationship between ‘the present’ and ‘presence’, the

Effects of density of geofoam cushion on seismic performance of the retaining wall: Experimental study [PDF]
In recent years, three important factors have been taken into account in designing safe and useful retaining walls in seismically active regions: cost, environment and earthquake performance.

Seismic Hazard Assessment: Conditional Probability [PDF]
In this exercise, students investigate the use of conditional probability (the likelihood that a given event will occur within a specified time period) in assessing earthquake hazards.

ABSTRACT This article presents a capacity‐based assessment procedure for beam–column (b–c) joints of reinforced concrete frames with floor slabs and transverse beams. The procedure extends a previously proposed assessment methodology for determining the hierarchy of strengths and the sequence of events in symmetrically reinforced planar b–c joints.

ABSTRACT The rapid development of new railway networks and the aging of existing infrastructure in seismic‐prone regions continue to motivate the need for efficient methods to simulate the dynamic behavior of coupled train track structure systems. While detailed train–structure interaction (TSI) models can capture complex mechanisms, they are often too

Artificial table testing dynamically adaptive systems [PDF]
Dynamically Adaptive Systems (DAS) are systems that modify their behavior and structure in response to changes in their surrounding environment. Critical mission systems increasingly incorporate adaptation and response to the environment; examples ...

Covariance Structure Modeling of Engineering Demand Parameters in Cloud‐Based Seismic Analysis
ABSTRACT Probabilistic seismic demand modeling aims to estimate structural demand as a function of ground motion intensity—a critical stage in seismic risk assessment. Although many models exist to describe the structural demand, few consider the covariance among engineering demand parameters, potentially overlooking a key factor in improving the ...
