In this study, the seismic response of a container crane under near-field and far-field ground motions was investigated using shaking table test on 1/20 scale crane. The designed fabricated based similitude laws, in which three independent quantities: geometric length, acceleration, elastic modulus, were used to design A series tests conducted at Seismic Research Test Center, Pusan National Uni...

administrative regulations for water flow decrease distribution efficiency and effect the economical operation of irrigation networks. complications in distribution systems and the decrease in availability of water require study of the hydraulic performance of existing flow control structures. control systems designed by neyrpic (zayandeh rud network) and usbr (doroodzan network) were investiga...

Patch antenna with double notches and triangular tapered feeding line has been investigated. It is observed that broadband matched double-notched patch antenna is suitable for tri-band operations from simulation and experimental results. It shows a measured return loss well below –10 dB in all three-frequency bands of operation. It has also been observed that the double notched conventional rec...

This paper examines differences in performances of a range of torsionally stiff and flexible single story buildings designed with the provisions of Iranian Standard 2800. Seismic nonlinear dynamic time history behavior of eight building models subjected to seven horizontal bi-directional design spectra compatible ground motions are investigated. These models cover a wide range of very torsional...

many pieces of research have investigated the environmental variable including environmental beliefs, values, attitudes, knowledge, and behaviors among iranian people, but their coverage has not gone beyond a few provinces. this research investigates the status of iranian's environmental values (in micro and macro level) in national level and gone beyond description by targeting explanatio...

Evansville, Indiana, is one of the closest large urban areas to both the New Madrid Seismic Zone, where large earthquakes occurred in 1811–1812, and the Wabash Valley Seismic Zone, where there is evidence of several large prehistoric earthquakes in the last 14,000 yr. For this reason, Evansville has been targeted as a priority region for urban seismic-hazard assessment. The probabilistic seismi...

Bandar Abbas (center of Hormozgan province) is the most important port city in the south of Iran because of its historical places, cultural, economic, social and political importance. High risk of earthquake occurrence in this city and its province indicates the necessity of surveying the seismic vulnerability of buildings. The object of this paper is collected from existing Buildings, compiled...

BACKGROUND The purpose of this study was to report interaction patterns among Iranian authors of emergency medicine using social network analysis methodology, focusing on coauthorship network. METHODS The bibliographic data of Iranian authors on the 'emergency medicine' field during the years 2001-2011 were retrieved from the Science Citation Index Expanded database. Co-occurrence matrices we...

This article presents numerical studies on semi-active seismic response control of structures equipped with Magneto-Rheological (MR) dampers. A multi-layer artificial neural network (ANN) was employed to mitigate the influence of time delay, This ANN was trained using data from the El-Centro earthquake. The inputs of ANN are the seismic responses of the structure in the current step, and the ou...
