Jacketing of reinforced concrete columns is a common and useful strengthening method. This method substantially improves mechanical properties of the column, such as flexural strength as well as shear and ductility. In this paper, the behavior of confined reinforced concrete columns are investigated. The results indicate that the method is more effective for slender columns in the region of the...

This paper reviews the different models commonly used in understanding Herodotus’evidence on Achaemenid Persian empire. It suggests that these approaches—for example, assessment of Herodotus’accuracy, level his knowledge, or sympathy for Persians—systematically underestimate complexity (and Greeks’) perspective empire: conflicted a participant rather than just detached observer.

Darius offered the political order of “king of kings” to solve the political crisis of his era. He legitimized it based on an order of gods. In his belief, the nature of politics was based on a dualistic religious worldview that is the fight between true divinity and false divinity’s will and performance in the world. In addition, the chief true divinity’s law was introduced as the principle or...

In this study, the co-operation of steel and concrete in composite columns is considered. Using numerical modeling to study the behavior of these sections, a new type of sections, namely Concrete Filled Double-Skin steel Tubular (CFDST) columns, is introduced. The parameters and techniques that influence the numerical simulation that bring this modeling closer to...

The Yale art historian George Hersey showed us the columns in Figure 1 and asked us whether the ideas of symmetry breaking could be used to help classify architectural columns. Provoked by this question and the intriguing columns in that figure, we attempted to answer Hersey in the following way. We view a column as a deformed cylinder and column symmetries as the subgroup of the symmetries of ...

The second season of the archaeological survey of Qeshm Island was conducted during the winter of 2012, during which the team identified a total of 138 sites. The preliminary analysis of the ceramic assemblage from these sites suggests that 5 sites date to the 3rd millennium B.C.(Bronze Age) and represent the earliest in the directory. The remainder includes 3 Iron Age, 4 Achaemenid, 23 Parthia...
