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 se...

Bridge expansion joints (BEJs) are equipped at the girder end of long-span railway bridges to ensure reliable transition track. BEJs should have suitable dynamic stiffness running safety and stability vehicle. To explore influence vertical on response vehicle, track, bridge, a three-dimensional vehicle-track-bridge coupled model is established, sleeper spacing vehicle speed taken into considera...

A butterfly web girder is a box that has discretely distributed side-surface openings. Due to these openings, girders show better aerodynamic performance than conventional girders. This study aims investigate the effects of openings on instability when it placed in tandem with another girder. In addition, this whether one affected by an adjacent series wind tunnel tests will be carried out and ...

The influence of composite girders on the modified buckling factor for columns was investigated in both braced and unbraced frames. girders' end conditions were represented as rigid hinged . Furthermore, based proposed stiffness parameter, derived formulation follows same assumptions standard effective length (K-factor). Moreover, suggested equations frames obtained using slope-deflection metho...

This article presents an experimental investigation on the bending capacity of steel-concrete composite truss girder (SCCTG). Four full-scale specimens named CB1, CB2a, CB2b and CB3 respectively, are tested and numerical analyzed. Stress distribution, load-displacement relationship, load-slip relationship and ultimate bending capacity of SCCTGs are investigated. The results show that SCCTG foll...

abstract: there is always a need to increase a distillate output of solar still. if plates will be used inside solar still then distillate output of solar still are expected to increase. hence, an experimental study is conducted to improve distillate output of basin solar stills by increasing the effective surface area with the help of different plates. for the purpose of experiment, three sola...
