The study aims to investigate wind effects on the equal area and same height building model having plan cross-sectional shape in form of regular irregular bulidings. ratio modification is kept for shaped models because limited studies are available such type comparison. responses structure resist load increased by applying these modifications corner configuration as cut, chamfer, fillet structu...

ABSTRACT: This paper deals with the determination of the ventilation efficiency (VE) indices, Purging Flow Rate, Visitation Frequency, and Staying Time of air pollutants, inside a domain located within an urban area. For the purpose of study, a wind environment of 100 x 100 x 75 m volume was considered and a two building model inside was adopted to perform the calculations. A void was construct...

The present work reveals a problem formulation to minimize material consumption and improve efficiency of diagrids to resist equivalent wind loading. The integrated formulation includes not only sizing of structural members but also variation in geometry and topology of such a system. Particular encoding technique is offered to handle practical variation of diagrid modules. A variant of Pseudo-...

This paper addresses essential components for predicting earthquake losses in the highly populated area in Dubai, UAE, namely the compilation, classification, design and idealization of the building inventory. Collecting the characteristics of the large and diverse building stock in Dubai is a challenging task. This is achieved using satellite images and confirmatory site visits. A GIS data of ...

modeling of relationship between ventilation rate of buildings and sick building syndrome symptoms hosseinpoor s , gholamiborujeni f *, mohammadian y received: 22 aug, 2013 accepted: 23 oct , 2013 abstract background & aims: indoor air pollution with microbilal, chemical and physical pollutants lead to sick building syndrome (sbs). suitable ventilation of buildings, is one of the best methods t...

Good daylighting design in buildings not only provides a comfortable luminous environment, but also delivers energy savings and comfortable and healthy environments for building occupants. The importance of using daylight in educational buildings is because of the synchrony of operating hours of the school and daylight plenitude the sky. Daylight improves environmental quality and saves energy ...

In this paper, we utilize rental ads to create realistic textured 3D models of building exteriors. In particular, we exploit the address of the property and its floorplan, which are typically available in the ad. The address allows us to extract Google StreetView images around the building, while the building’s floorplan allows for an efficient parametrization of the building in 3D via a small ...

This study presents a novel approach for building change detection from digital surface models (DSMs), which are generated from the images acquired by a multi-line digital airborne sensor ADS40. Our approach is based on building extraction, which is one of the most challenging research fields. A scheme is proposed that allows efficient integration of a local surface normal angle transform (LSNA...

In this paper we describe a concept to manage and develop a web based virtual 3D scene, based on CityGML LoD 2 models, DTM tiles, ortho-photos and energy simulation results of specific heating demand and photovoltaic potential generated from SimStadt simulation platform, by integrating it on ESRI 3D City Information Model (3DCIM) platform. The final output results into a web based 3D visualizat...
