Although a wealth of knowledge on the behavior of steel moment frame structures has been gained from past experimental studies, there are only a limited number of system-level tests examining seismic response near collapse. Such experimental data is essent ...

This paper quantifies the collapse risk and earthquake-induced economic losses of steel-frame buildings with special concentrically braced frames designed in urban California. A probabilistic building-specific loss estimation methodology that can explicitl ...
This paper addresses seismic vulnerability assessment at an urban scale and more specifically the capacity curves involved for building damage prediction. Standard capacity curves are a function of predefined building typology and are proposed in the Risk- ...
Existing school buildings in Switzerland that have been designed from the early 1970s typically utilized a modular architectural layout and structural system commonly known as CROCS (Centre de rationalization de d’organisation des constructions scolaires). ...
bstract A wide range of approximate methods has been historically proposed for performance-based assessment of frame buildings in the aftermath of an earthquake. Most of these methods typically require a detailed analytical model representation of the resp ...

Laboratory experiments reproducing seismic slip conditions show extreme frictional weakening due to the activation of lubrication processes. Due to a substantial variability in the details of the weakening transient, generalization of experimental results ...
This paper summarizes the findings of a long term experimental program corroborated with detailed finite element simulations that investigated the hysteretic behavior of wide-flange columns in steel moment-resisting frames (MRFs) designed in highly seismic ...
The concept of simultaneous source has recently become of interest in seismic exploration, due to its efficient or economic acquisition or both. The blended data overlapped between shot records are acquired in simultaneous source acquisition. Separating th ...
Recent estimates of fracture energy G (') in earthquakes show a power-law dependence with slip u which can be summarized as G (') ae u (a) where a is a positive real slightly larger than one. For cracks with sliding friction, fracture energy can be equated ...
A series of seismic tests were conducted on a 1½-bay by 1½-story special steel moment-resisting frame subassembly from the onset of damage through incipient collapse. These tests were conducted using hybrid simulation with substructuring as a mean to demon ...
