| 内容記述 | Many bridges are supported by hinge at one end and by a slide at the other. Though this kind of support system is popular, the maintenance can be quiet expensive as it is liable to such accident as sticking of sliding shoes owing to rusting. For this reason, influences of fixing the girder at both ends and removing the expansion joint have been studied taking the mutual reactions among supper-structures, substructures, and foundation into account. In this analysis, following assumptions are made: (1) that the structure is symmetric; (2) that only the single span type bridge may be considered to be adequate for the purpose ; (3) that the girders are to be connected to the abutment after the slab has been layed and hardened; and (4) that, in accordance with the Japanese standard specification, a temperature change of pm 30C is adequate. It is to be understood, further, that the spring coefficients of the earth behind the abutment k, the resistance to shearing force of the footing bottom Kh, and the resistance to rotation of the footing bottom Kr are to be calculated on the Japanese standard specification, and that thrust is computed only the live load and the temperature effect are considered, disregarding the dead load, if any. For the axial force and the additional bending moment acting on the girder, case of (A) the whole abutment is touched to the earth behind the abutment, (B) the abutment is stripped of the earth from the top, and (C) the abutment is detached at the bottom, are subjected to numerical with the span length, the abutment hight, and the value of the standard penetration test (the N value) as the parameters. It was found : (1) that the axial force increase in proportion to the span length when the temperature change is to+30C, but in proportion to its square if it is to -30C, though with magnitude much smaller than the former because of the yielding of the earth behind abutment ; (2) that as the temperature rises, the additional moment induced at the end of the girder and the top of the abutment becomes generally larger than the fixes moment when N=I, namely in favor of safety, because it acts in the opposite direction to the moment due to the load ; and (3) that when the temperature rise is accompanied by live load, the girder stress is decreased in proportion to the increase in the additional moment, the latter acting in a disadvantageous direction even though its magnitude is only a few %, hence insignificant for the safety. It may be concluded therefore that fixing the beam to abutment does not bring about particularly unfavorable effects on the bridge, even though axial force and additional moment is induced on the top of the abutment. | |||||
