内容記述 |
Seismic retrofitting has recently become crucial for buildings designed under old seismic codes. Post-installed anchors or disk-type shear keys are generally applied to joints of seismic retrofitting structures, which are further anchored to the existing members by applying epoxy adhesives. Although epoxy adhesives have been studied extensively, few studies exist on cement-based adhesives. Therefore, we conducted a pull-out test, a shear loading test, and a two-dimensional (2D) FEM analysis to investigate the adaptability of cement-based adhesives to disk-type shear keys. In Chapter 2, the test plans for the pull-out and shear loading tests are detailed. Nine specimens were prepared for each test. The parameters of the pull-out test include the concrete compressive strength σB (10-30 N/mm2), adhesive type (epoxy or cement-based adhesive), and anchor bolt type (fully threaded bolt or round steel bar). The parameters of the shear loading test are σB and adhesive type. In Chapter 3, the FEM analysis is outlined. In this analysis, the concrete and the steel are considered as a plane stress element, the stud bolts as a beam element, and reinforced bars as a truss element. A concrete thickness of 135 mm (=1.5Rd, where Rd is the diameter of the steel disk) is considered as the damage area of the disk-type shear key. The analytical parameters are the concrete compressive strength σB and the adhesive type. In adhesive type, the case of “unbonded” is also added as a parameter. Chapter 4 describes the test results. According to the results of the pull-out test, use of the cement-based adhesive with a fully threaded bar resulted in the same maximum bond stress as with epoxy adhesives. However, the maximum bond strength was 0.2-0.3 times the bond strength in case of a round steel bar. The shear loading test results indicated that the shear forces of the cement-based adhesive were slightly smaller than those when the epoxy adhesive was used. Chapter 5 describes the analytical results. First, the bond-slip behavior of adhesives was modeled from the results of the pull-out test. The analytical outcomes of the nine cases were calculated. The Q–δ curves obtained from the analysis and the experiment were similar. Moreover, the shear forces in the unbonded case were smaller than those in case of epoxy and cement-based adhesives because the bearing resistance area was smaller because of the pulling out of the anchor bolt. Chapter 6 presents the conclusions of the study, which are summarized as follows: 1) The results of the pull-out test using an epoxy adhesive and a round steel bar show a safety ratio exceeding 1.0, but with a higher standard deviation. 2) The pull-out test results indicate that the combination of a cement-based adhesive and a fully threaded bar resulted in the maximum bond stress same as that in case the when an epoxy adhesive was used. However, a round steel bar exhibited the maximum bond strength that was 0.2-0.3 times the bond strength. 3) The shear loading test results show that the maximum shear force of the specimens using cement-based adhesives was approximately 10% smaller than that of the specimens using epoxy adhesives. These maximum shear forces were, however, higher than the calculated shear strength in most specimens. 4) The shear behavior could be reproduced by the 2D FEM analysis by setting the concrete element thickness to 1.5 Rd. 5) The bond strength and the vertical displacement of the anchor bolt obtained by the analysis were smaller and larger, respectively, compared with the experimental results. 6) From these investigations, it was concluded that cement-based adhesives can be applied to disk type shear keys. |
