Analysis of Dynamic Response and Ultimate Strength for Box Girder under Bending Moment
نویسندگان
چکیده
The box girder can be seen as a kind of simplified ship structure that withstand vertical bending moment. Dynamic loads play an important role in structural safety analysis, such bow slamming during harsh sea conditions. In this paper, the dynamic elastic–plastic response and ultimate strength under moment are analyzed. A with same cross-section scantlings span length Nishihara experiment is selected analysis object. Based on model results, non-linear FE method validated to capture Then, six girders were designed study critical influence factors moment, including length, plate thickness, mass density load excitation period. On basis response, evaluation criterion limit state for proposed paper. Compared static change discussed detail obtain general principal analysis. conclusions paper provide guidance evaluation.

Ultimate strength analysis of composite sections under biaxial bending and axial load
A new generic fiber model algorithm is presented that allows for the efficient analysis of arbitrary composite sections under biaxial bending and axial load. The geometry of the cross section is described by multi-nested curvilinear polygons i.e. closed polygons with edges that are straight lines or circular arcs. The polygons may be convex or concave and may contain openings. The stress–strain...

15 صفحه اولInfluence of Sudden Column Loss on Dynamic Response of Steel Moment Frames under Blast Loading
Modeling buildings response to blast and subsequent progressive collapse interested more and more researchers during the past two decades. Due to the threat from extreme loading, efforts have been made to develop methods of structural analysis and design. In this paper, progressive collapse capacity of steel moment frames was first investigated using alternate load path method, then a nonlinear...
متن کاملresponse articles: micro and macro analysis
the present study reports an analysis of response articles in four different disciplines in the social sciences, i.e., linguistics, english for specific purposes (esp), accounting, and psychology. the study has three phases: micro analysis, macro analysis, and e-mail interview. the results of the micro analysis indicate that a three-level linguistic pattern is used by the writers in order to cr...
