The outrigger arm system and belt truss with braced core in the center of the structure surrounded by belts truss, is an efficient and reliable system for high-rise buildings against severe lateral forces such as earthquake and wind. The purpose of this research is investigating the outrigger arm system and belt truss with the braced core under lateral loads. Another purpose of this research is...

recently, with increasing of interest of all people especially young people and teenagers to sports in Iran in parallel the tendency of investors both in governmental and private parts is increased ,and in this part the special places and spaces of sport was not departed , and billion Rials (Iran’s currencies) is paid for making some places for sport or equipped the old building .In this ...

Microburst can produce downdraft and strong divergent outflow wind, whose characteristics are distinct from the atmospheric boundary layer (ABL) wind. In the present study, microburst-wind loading effects on low-rise structures a cubic-shaped building, a grain bin and two gable-roofed buildings – are evaluated and compared by performing laboratory tests on scaled models using a microburst simul...

An approach to generate 3-D models of buildings from lidar data collected from an urban setting is presented. The present research focuses on extracting roof structures from a point cloud of a building using a combination of datamining techniques. To extract the roof structure, an assumption of planarity has been made, i.e. it is assumed that the roof can be modeled by a set of planar segments....

A roof provides protection to be safe from direct sunlight. From the shelter, shadow alone is not expected. Durability, sustainability, less life cycle cost, and low maintenance cost are expected from a selected roof. The world has a thirst to have a best roof. No roof will fulfil the requirement of humanity since the climatic conditions are different. Hence the roof should be selected accordin...

The roof garden has great functioning of smoothing the shortage of land resource in the city and making use of the land resource diversity and efficiently. The modern era, following the fast development of economic and society, people have a high claim to green roof or roof garden. It is an efficient and reasonable way to exploit the open space the roof of the building. From the classic roof ...

In this paper, we proposed an automatic procedure to reconstruct building outline using building data and stereo aerial images. Our methods focused on the outline of building, excluding the inner structure of roof surface. This procedure includes five steps, 1) to produce the edge gradient images by Canny Detector, 2) to defined the valid workspace in object space and image space by building da...

A monitoring system that uses applied geomatics techniques, including terrestrial laser scanning and videogrammetry, has been developed in order to determine the behaviour of as-built membrane roof structures. To accommodate the constraints involved in measuring such structures, for example uniform surface texture and unreachable height, the system adopts a non-contact targeting methodology to ...

To mitigate the urban heat island effect has become a global issue when we are faced with the challenge of climate change. Through literature review, plant photosynthesis can reduce the carbon dioxide and mitigate the urban heat island effect to a degree. Because there are not enough open space and parks, green roof has become an important policy in Taiwan. We selected elementary school buildin...

The incident angle of ground motion is one of the sources of uncertainty in the seismic response of buildings. Moreover, understanding the structural response to the impose ground motion may cause significant changes in the maximum response of buildings. In order to investigate the effect of the spatial distribution of orthogonal components of earthquake strong motion on the structural response...
