Abstract: Using inappropriate system overstrength factors may lead to weak seismic performance or uneconomic results. Regulations suggest the suitable system overstrength factors for various seismic force-resisting systems. This is while a lot of parameters might affect on this factor. In this paper, the effects of various parameters such as the type of the moment frame, Seismic Design Category (SDC) and height of the building on overstrength factors of steel Moment Resisting Frames (MRF) are investigated. Hence, 12 buildings with perimeter steel MRF are designed three-dimensionally based on ASCE/SEI 7-10, AISC-LRFD 360-05 and AISC 341-05 regulations. Then, 24 two-dimensional MRFs of these buildings are simulated in OpenSees software and by conducting the Nonlinear Static Analysis (NSA); pushover curves of these structures are obtained. Finally, having these curves, relevant overstrength factors are gained. The results demonstrate that although altering the mentioned parameters, changes the over

Abstract: This paper deals with the developments in the field of accident modeling regarding Unsignalized intersection. A literature review of old techniques used for modeling is presented. More emphasis is being given to the parametrical changes that took place over the period of time. Three domains of intersection’s safety are discussed namely vehicular safety, bicycle safety and pedestrian safety. Statistical techniques used in the above three domains are described along with the parameters used for analysis.
