Seismic Performance of a Special Steel Moment-Resisting Frame Subassembly from the Onset of Damage through Collapse

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 ...

Utilization of wavelet-based damage-sensitive features for structural damage assessment of steel braced frames

Dimitrios Lignos, Seong-Hoon Hwang

Rapid structural damage assessment methodologies for engineered facilities are essential in order to properly allocate and ensure efficient use of emergency rescue forces, minimize business interruption and perform effective repairs in damaged infrastructu ...

Characterization of Cold-Formed Steel Framed/Wood Sheathed Floor and Roof Diaphragm Structures

Dimitrios Lignos

The seismic in-plane response of cold-formed steel (CFS) framed diaphragm structures has not been the subject of extensive study. The information available specific to diaphragm design in the North American CFS design standard is based on limited experimen ...

Usefulness of ambient-vibration measurements for seismic assessment of existing structures

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

A large number of buildings in regions with low to medium seismic hazard have been designed without considering earthquake actions. Retrofitting of all buildings that fail to meet modern code requirements is economically, technically and environmentally un ...

Seismic retrofit of cultural heritage buildings – when less is more

Katrin Beyer, Francesco Vanin, Michele Godio, Andrea Penna

In 1356, Basel was subjected to an earthquake with an estimated magnitude of 6.6; it is the largest known historical earthquake in central northern Europe. During this earthquake and the fire that followed large parts of Basel were destroyed. Such an event ...

Experimental and Numerical Evaluation of Steel Columns for Performance-Based Seismic Assessment of Steel Moment Frames

Dimitrios Lignos, Ahmed Mohamed Ahmed Elkady, Alexander Riley Hartloper

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 ...

Approximate Method for Performance-Based Seismic Assessment of Steel Moment-Resisting Frames

Dimitrios Lignos, Seong-Hoon Hwang

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 ...
