analysis of the performance of this new algorithm for an urban and urban-rural boundary. An automatic height extraction algorithm using a stereoscopic approach and a building detection algorithm using a monoscopic approach are introduced. The auAUTOMATIC HEIGHT tomated height extraction is done using a pyramidal EXTRACTION matching strategy and a silhouette mask made from linHigh resolution urb...

This paper is an extension of an earlier work on “building regulations‟ impact on natural ventilation in Dhaka‟s apartment buildings”. Four schemes of building regulations (each offering different „maximum allowable footprint‟ with a different „maximum building height‟) were examined. Due to unavailability of large computation resource, only bottom floors, least privileged in terms of wind acce...

Due to an increasing amount of aerial data there is significant demand in automatic large-scale modeling of buildings. This work presents an image-driven method for automatic building extraction and 3D modeling from large-scale aerial imagery. We introduce a fast unsupervised segmentation technique based on super-pixels. Considering the super-pixels as smallest units in the image space, these r...

Building code-related literature provides recommendations on normalizing approaches to the calculation of the dynamic properties of structures. Most building codes make a distinction among types of structural systems, construction material, and configuration through a numerical coefficient in the expression for the fundamental period. The period is then used in normalized response spectra to co...

High tall buildings are more susceptible to dynamic excitations such as wind and seismic excitations. In this paper, design procedure and some current applications of tuned mass damper (TMD) were studied. TMD was proposed to study response of 20 storey height building to seismic excitations using time history analysis with and without the TMD. The study indicates that the response of structur...
