by identifying the damage index of a structure, in addition to a correct understanding from real behavior of the structure, the required criterion for strengthening would be given. researchers have given many relations for determination of damage index but such relations have been based upon laboratory methods which challenge their usage in a broad term. in this paper two new methods are given ...

considering concepts such as emphasize on the role of the all stakeholders in urban regeneration, is one of the important and fundamental principles. this is important because in most cases, the private sector, government and municipal are considered more in process of intervention in distressed area and play a key role in this situation. but the role of people is often considered minor. empowe...

in our present research, we focus on the modeling of airflow related to natural disasters, such assand accumulation, with urban form studies. the objective is to find which urban form can promote sand passing andreduce as much as possible stagnation of sand in the building area (streets, alleys, etc.). the urban form design will bediscussed through the simulation of airflow by using computation...

Based on features on digital map, such as building contour and road polyline, we are proposing the system to generate 3-D Urban Model automatically, integrating GIS and CG. 3-D Urban Model is the important information infrastructure that can be utilized in several fields, such as landscape evaluation, urban planning, civil engineering, architecture, disaster prevention simulation, etc. When a r...

Abstr act: Visual Information Systems for urban planning can be produced in a variety of ways. In this paper we give an account of research into integrating scanned data with urban data sets to produce 3D applications that span built environment spatial scales from building elements to the whole city. In our research, 3D laser scanner is used to capture 3D building models as a way of developing...

A high-fidelity and real-time rendering urban building model was implemented through the simplification of 3D building groups. An approach to simplify a single 3D building has been addressed for generating a levels-of-detail (LOD) building model in nearby urban regions. In farther regions, a single-chain cluster was used to collect footprints of neighboring building groups. To effectively merge...

Urban heat island (UHI) effects can strengthen heat waves and air pollution episodes. In this study, the dampening impact of urban trees on the UHI during an extreme heat wave in the Washington, D.C., and Baltimore, Maryland, metropolitan area is examined by incorporating trees, soil, and grass into the coupled Weather Research and Forecasting model and an urban canopy model (WRF-UCM). By param...

This paper presents a method for automatic derivation of urban structures types with focus on residential areas. It is based on scanned topographic maps at scale 1:25k and a given urban block geometry from a national topographic database. The procedure consists of five steps: (1) definition of a typology of urban structures, (2) extraction of building footprints, (3) computation of measurements...
