Modelling and Seismic Response Analysis of Existing URM Structures. Part 2: Archetypes of Italian Historical Buildings
Sergio Lagomarsino,Serena Cattari,Michele Angiolilli,Stefano Bracchi,Maria Rota,Andrea Penna +5 more
TL;DR: In this article , the authors present a comprehensive strategy for analysing the complex seismic response of five Italian historical URM buildings, corresponding to different periods until 1920s, using pushover and dynamic analyses of 3D equivalent frame models.

A methodological framework to relate the earthquake-induced frequency reduction to structural damage in masonry buildings
TL;DR: In this article , a model-driven vibration-based methodology was proposed to support the assessment of the damage level in masonry buildings hit by earthquakes, where the authors exploited, in the pre-event phase, synthetic equivalent-frame modelling and nonlinear dynamic analyses to systematically relate the gradual reduction of natural frequencies to increasing levels of structural damage.

Probabilistic Basis for 2000 SAC Federal Emergency Management Agency Steel Moment Frame Guidelines
TL;DR: In this paper, a formal probabilistic framework for seismic design and assessment of structures and its application to steel moment-resisting frame buildings is presented, based on realizing a performance objective expressed as the probability of exceeding a specified performance level.

The behavior of inverted pendulum structures during earthquakes
TL;DR: In this article, an analysis is made of the rocking motion of structures of inverted pendulum type during the Chilean earthquakes of May, 1960, and it is shown that there is a scale effect which makes tall slender structures more stable against overturning than might have been expected.
