dynamic behavior of the wind-excited-benchmark-building using semi-active electromagnetic friction dampers (saemfds), with modulated homogeneous friction algorithm is presented. the performance of the benchmark building is studied under across wind loads by installing the saemfds with smooth boundary layer semi-active friction (sblsaf) algorithm. the governing equations of motion are solved by ...

Building construction challenge, in recent years, is the reduction of social, economical and environmentalimpacts along with economical nature and increasing life quality, as here sustainable construction is important. Pre-fabrication and industrialization are referred as a solution of sustainable construction due to some of its main characteristics consisting of many sustainability aspects. Du...

The present work aims to introduce an efficient set of high spatial resolution (HSR) images in order to more fairly evaluate building detection algorithms. The introduced images are chosen from two recent HSR sensors (QuickBird and GeoEye-1) and based on several challenges of urban areas encountered in building detection such as diversity in building density, building dissociation, building sha...
