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 body of residential complexes is affected by social interactions between residents over time. Of the most important places for social communications are bazaars as the backbone of Iranian cities. Ancient bazaar of Babol in north of Iran contains natural features which makes a special sense of place. This essay tries to answer to how concept of sense of place is presented and what are factor...

In the present work, the exergy analysis and economic study of 3 different samples of threecomponent mixtures have been investigated (ESI>1, ESI≈1, and ESI<1). The feed mixture has been tested under three different compositions (low, equal, and high contents of the intermediate component). A quantitative comparison between simple and complex configurations, considering thermally coupled, thermo...

Wooden pallets are the largest single use of sawn hardwood logs in the USA. Unfortunately, millions of wooden pallets are discarded annually due to damage or because their low cost makes them readily disposable. High quality wooden pallets, on the other hand, promote longevity and re-use. However, building durable pallets requires high quality pallet parts. Because manual grading and sorting of...

The mechanical response of the wooden support of Mona Lisa to the action of the frame has been modeled using finite elements and compared to observations by optical techniques. The risk of propagation of the existing crack, estimated through the calculation of an elastic energy release rate, was found negligible. Introduction The application of wood science and engineering principle to improve ...

It consists of a block of wood 93 in. by 3 in. by 2 in. into which have been drilled forty-eight holes of j in. diameter in four rows of twelve. The top of the wooden rack is covered by a thin sheet of white plastic, drilled with holes of a similar size and position to those on the wooden block. Fixation on to the wood is secured by glue and six -brass screws. The plastic top has the advantage ...
