TLDR
In this article, the authors consider the vulnerability of reinforced concrete buildings to strong ground shakings and present a quantitative analysis of structural damage under random earthquake excitations, based on qualitative engineering judgment.Abstract:
Experiences from past strong earthquakes, such as the 1968 Miyakiken-Oki earthquake in Japan and the 1971 San Fernando earthquake in California, have shown the vulnerability of reinforced concrete buildings to strong ground shakings. For economic reasons, however, some level of damage should be expected and permitted in the aseismic design of structures, particularly of low-rise buildings. In spite of this recognition, the potential seismic damage of structures and the associated aseismic provisions are based largely on qualitative engineering judgment. In order to assess the seismic safety of reinforced concrete buildings, the quantitative analysis of structural damage under random earthquake excitations needs to be improved.read more

Derivation of vulnerability functions for European-type RC structures based on observational data

TL;DR: In this article, the authors reviewed existing vulnerability relationships for reinforced concrete structures with a view to their application to a European (and similar) seismic risk assessment scenario, and derived new empirical fragility curves for reinforcedcrete building populations based on a data bank of 99 post-earthquake damage distributions observed in 19 earthquakes.

Random vibration of hysteretic systems under bi-directional ground motions
TL;DR: In this paper, a random vibration method is developed for the response analysis of hysteretic structural systems under stochastic two-dimensional earthquake excitations, where the biaxial restoring force is modelled by coupled nonlinear differential equations; the response statistics are obtained using the equivalent linearization technique.

Smart aggregates: multi-functional sensors for concrete structures—a tutorial and a review
TL;DR: In this paper, the authors proposed a multi-functional smart aggregate for early-age concrete strength monitoring, impact detection and structural health monitoring, which can be applied to the comprehensive monitoring of concrete structures from their earliest stages and throughout their lifetime.
