Article
Full-text available
The safety and resilience of school buildings against natural disasters is of paramount importance since schools represent a reference point for communities. Such significance is not only related to the direct consequences of collapse on a vulnerable part of the population, but also due to the importance of schools in the post-disaster recovery. Th...
Conference Paper
LNEC has developed a seismic risk assessment study addressing 32 schools of the secondary and of the 2nd and 3rd cycles of basic education that are part of the school buildings portfolio managed by the Lisbon City Council (CML). In this communication, the study methodology and its main conclusions are presented. Based on the assessment of the seism...
Conference Paper
Full-text available
A large number of variables are involved in the simulation of structural fire response. As a consequence, structural fire analysis may be extremely costly. This study aims at identifying the most important variables affecting the response of steel structures under and immediately after being subjected to structural fire loading. Two case study exam...
Conference Paper
Full-text available
In steel moment resisting frame structures, beams, columns, and connections can experience large strains and sustain strength and stiffness deterioration during intense earthquake ground motion shaking. In this paper, bilinear models accounting for strength and stiffness deterioration of both beams and beam-column connections are studied. Beams are...
Article
Full-text available
This paper presents an analytical study evaluating the influence of ground motion duration on structural damage of 3-story, 9-story, and 20-story SAC steel moment resisting frame buildings designed for downtown Seattle, WA, USA, using pre-Northridge codes. Two-dimensional nonlinear finite element models of the buildings are used to estimate the dam...
Article
Full-text available
Finite-length plastic hinge (FLPH) models have shown advantages over the concentrated plasticity hinge (CPH) models. However, empirical phenomenological relationships, such as Modified Ibarra-Medina-Krawinkler (ModIMK) deterioration model, were mainly calibrated for use in CPH models. ModIMK relationships are versatile and have been applied to stee...
Conference Paper
Full-text available
Subduction zone earthquake motions present a significant hazard in Northern California and the Pacific Northwest, as well as other parts of the world. Compared to shallow crustal earthquake motions, subduction zone earthquake motions present longer duration and lower frequency content. As a consequence, the response of structures subjected to these...
Article
Full-text available
The use of empirically calibrated moment-rotation models that account for strength and stiffness deterioration of steel frame members is paramount in evaluating the performance of steel structures prone to collapse under seismic loading. These deterioration models are typically used as zero-length springs in a concentrated plasticity formulation; h...
Article
Full-text available
The paper presented herein proposes a reliability-based framework for quantifying the structural robustness considering the occurrence of a major earthquake (mainshock) and subsequent cascading hazard events, such as aftershocks that are triggered by the mainshock. These events can significantly increase the probability of failure of buildings, esp...
Conference Paper
Full-text available
The problem of fire following large earthquake raises significant concerns in earthquake prone areas. The evaluation of the occurrence and consequences of fires following earthquakes are a highly nonlinear and uncertain problem. The purpose of this paper is to report the ground work that the authors have been developing on the topic of performance-...
Conference Paper
Full-text available
Earthquakes cannot be seen as isolated hazard events. High intensity earthquakes usually lead to secondary hazard events, such as fire, blasts, aftershocks and tsunamis, whose consequences have significant impact on life safety in post-mainshock risk scenarios. These secondary events that follow major earthquakes are not considered in codes. In thi...
