開口形 隔壁을 갖는 상자형에 대한 實驗的 硏究 = Experimental Study of Box Girder with open Diaphragm under Eccentric Loads Effects

다국어 초록 (Multilingual Abstract)

Box Girder is the popular bridge type for long span or curved bridges because of its structural advantage on torsional stiffness. It has been the practice of designers to provide diaphragms in these boxes but often the position and strength of the diaphragms has been determined arbitrarily rather than on any well founded basis. The presence of diaphragms in the box introduces some additional dead load, but this effect is not likely to be a serious factor in the design.
The analysis on this thesis expanded that analogy for BEF and was able to calculate warping stresses, distortion stressesand displacement of each point according to the position of diaphragms. And this method was verified accuracy of result as compared with the experimental result.
The experimental results of the model box girder proved the effective value of the analysis on this thesis, and behavior of box girders that was measured by eccentric load showed up aspects of displacements, strains of each point according to the load size.
