Abstract Traditional shape and stress control of structures use many actuators require enormous time to find reasonable solutions that need designers input specific target displacement stress. This study employs a linear technique static pin-jointed assemblies as theoretical advancement prior works provides comparative analysis against previously established works. The evaluates the proposed me...

The earthquake performance of structures with seismic isolation is much better than that fixed-base structures, and the application insulation ensures both structural integrity protection items present in structures. base-isolation system used to extend fundamental period vibration structure obtain higher value from base-isolated relative structure. Historical masonry mosques could be strengthe...

Nowadays, in order to increase construction of tall structures, the importance choosing optimum systems, with a huge energy absorption capacity against wind and earthquake loads, has been widely considered. Since four decades ago, steel shear walls had used as stiff high performance lateral system. This study is about effect concrete filled tubes (CFT) columns vertical boundary elements wall on...

In recent years, the devastating earthquakes that occurred in many parts of world have made it even more important design earthquake-resistant structures and earthquake performance assessment existing structures. When innovative systems are examined building design, is seen depending on developments performance-based designs come to fore addition force-based design. This paper provides a new me...

in this paper, seismic behavior of the existing buildings equipped by friction dampers is studied. seismic performance of6-story, 9-story and 12-story steel buildings with damper and without damper were studied. the finite element modeling technique (sap2000 software) is used for analysis. time history analyzing was done to achieve this purpose. for nonlinear dynamic analysis, the responses of ...

offshore jacket-type towers are steel structures designed and constructed in marine environments for various purposes such as oil exploration and exploitation units, oceanographic research, and undersea testing. in this paper a newly developed meta-heuristic algorithm, namely cyclical parthenogenesis algorithm (cpa), is utilized for sizing optimization of a jacket-type offshore structure. the a...
