Description

There is the case to install a steel bracket for end of the abut widening and a steel member for prevention cable for collapse of bridge setting in the existing concrete pier for seismic reinforcement by anchor bolts of the secondary execution. Anchor bolts of the secondary execution are necessary a drilling to the existing concrete deeply and there is a problem in execution characteristics to be in danger to injure inside steel materials. Therefore the fundamental performance of the secondary execution anchor bolt that shortened fixation length to 150 mm was examined, it assumed adoption to the bracket structure that only shear power acted on mainly. As a result, if it could prevent pulling destruction of the concrete at a shallow position, or find the adhesion proof stress of the anchor bolt in the deep part from the destruction starting point more than a form of corn destruction proof stress, and prevent partial compression destruction of the outer layer, it was shown the possibility that could expect reliable performance of load resistance by use for structures that shear resistance is dominant.
