This paper reviews contemporary trends in the management of the crisis phase of disasters.
It charts the recent history of emergency preparedness in the light of a basic distinction …

This paper presents an experimental investigation on the behavior of cold-formed steel
(CFS) battened built-up columns with unstiffened channel chords. A total of five specimens …

Built-up battened columns are lightweight and have a larger moment of inertia when
compared with columns made by a single profile. However, these columns have shown poor …

A phase picking algorithm has been developed for P-wave arrival detection and picking on a
3-component broadband seismogram. The algorithm is based on Wavelet Transform, Akaike …

In the 2017 earthquake event in Kermanshah, a western province of Iran, severe and near-to-
collapse damage was observed in a significant number of low-rise steel moment framed …

Topographic conditions play an important role on the modification of seismic ground motion.
Therefore, their effects may become crucial in the selection or simulation of ground motion …

The significance of near-surface attenuation in bedrock, as distinct from attenuation in
unconsolidated soft soil sediments, has been identified. The k parameter, which …

In this paper, a mathematical model is presented for free vibration analysis of symmetric plan
framed tube systems in tall buildings. Then, a closed form solution is derived for obtaining …

Earthquake fault ruptures may emerge at the ground surface causing large differential
movements. Fault ruptures can cause significant damage when they emerge at or adjacent …

In the last couple of decades, the built-up sections, instead of standard wide-flange profiles
in the shortage, have been widely used in the columns of steel frames in Iran. However, the …
