Natural hazards risk assessment requires data on the built environment. This paper reports an image analysis method that can extract building features, mainly roof plan areas, for potential vulnerability analysis. Both pixeland object-based image processing methods are adopted. First, red/green/blue colour bands and image textures are incorporated in a supervised artificial neural network class...

Due to the recent advancement in procedural generation techniques, games are presenting players with ever growing cities and terrains to explore. However most sandbox-style games situated in cities, do not allow players to wander into buildings. In past research, space planning techniques have already been utilized to generate suitable layouts for both building floor plans and room layouts. We ...

This work investigated the degrees to which energy use in laboratory buildings may be influenced by interior space planning and/or the ways space is used. The potential influences of typical open, mixed and closed plan layouts and their space utilisation densities/intensities were investigated on a good-practice base case using the TAS, Lightscape and Excel software packages. The peak winter re...

Architectural layouts of reinforced concrete buildings often require structural walls, with varying dimensions, to be placed in an asymmetric plan configuration. During seismic excitation the asymmetry induces a torsional component of response, which can impact negatively on the performance of the building by increasing demands on both structural and nonstructural elements. Furthermore, the tor...

A widely used morphometric method (Macdonald et al. 1998) to calculate the zero-plane displacement (zd) and aerodynamic roughness length (z0) for momentum is further developed to include vegetation. The adaptation also applies to the Kanda et al. (2013) morphometric method which considers roughness-element height variability. Roughness-element heights (mean, maximum and standard deviation) of b...

We present a knowledge-based system for automatic 3D building reconstruction from aerial images. Our approach relies on combining pairs of stereo images with 2D GIS map and domain knowledge. Since most buildings can be described as aggregation of simple building types, the domain knowledge is represented in a building library containing building primitives (flat, gable, and hip roof building). ...

Problem statement. Ukraine has a large number of waterways and access to the sea. They are unlimited reserves energy resources that can be used for benefit people, but at same time spring floods danger, therefore construction buildings on water is partial solution this problem. The coastal zone favorable in terms climatic conditions urban development. Increasing comfortable safe housing cities,...

In order to systematically investigate the gust effect factor for rigid buildings, derivation of in ASCE 7–16 is carefully reviewed and scale model pressure tests were carried out rectangular-plan high-rise buildings with plan aspect ratios ranging from 0.11 9. The aerodynamic admittance function (AAF) area-averaged coefficients base drag obtained discussed detail. results show that AAF has dir...
