the construction of underground tunnel plays a more and more important role in the development of big cities. one of the most important problems caused by the construction of the tunnel is that underground excavation will cause large settlement of the ground and buildings. previous studied showed the difference between numerical and experimental results. in this study the case study of niyayesh...

preparing thermal comfort conditions in outdoor public spaces is one of the considerations of architectural design. if the constructed area does not support comfortable conditions in outdoor spaces, it will cause microclimatic problems for pedestrians and adjacent buildings. regarding the different thermal comfort conditions in outdoor spaces in comparison with indoor, several indices have been...

In order to enable multi-scale urban visualization, multiple model representations at different levels of detail (LoDs) need to be produced (like by generalization) in advance or on the fly. At local scale, building groups are involved and at least medium LoD is needed in terms of visual perception. Motivated by such demands, this article proposes a novel method for generalizing 3D building gro...

The present work aims to introduce an efficient set of high spatial resolution (HSR) images in order to more fairly evaluate building detection algorithms. The introduced images are chosen from two recent HSR sensors (QuickBird and GeoEye-1) and based on several challenges of urban areas encountered in building detection such as diversity in building density, building dissociation, building sha...

The envelope (façade) of a building is the part that forms primary barrier to its environment. Most new and modern office buildings have glazed are usually built-in city centers. concept double-skin façade was born as consequence urban noise. principal noise source in areas traffic Using can be solution ensures good sound insulation for building. This study presents experimental results obtaine...

Abstract Groups of contiguous unreinforced stone masonry buildings are a common type housing seen in old European downtowns. However, assessing their response to earthquakes poses several challenges the analysts, especially when units laid out compact configurations. In fact, those circumstances modeling technique that allows for dynamic interaction is required. The numerical study carried this...

Increasing the population, urbanization has led to the rapid construction of buildings. Due to space constraints and an increase in land cost, these buildings are built too close to each other and can cause damage under dynamic actions such as earthquakes. A new technique, known as Structural coupling, has been developed recently, has found very effective in dissipating the dispersive vibration...
