As a structural characteristic of external seismic retrofitting, the existing frame and reinforcing frame are eccentric. Therefore, in addition to the shear force, there are also compression force and tensile force due to the eccentric bending moment acting on the joints, so that the joints are in a combined stress state in external seismic retrofitting. There are few studies on post-installed adhesive anchors under a combined stress state, and it is difficult to grasp in detail its mechanical behavior when subjected to combined stress. For that reason, the current design method suggests the use of reduction factors which are based on engineering judgment. This paper investigates the mechanical behavior of the post-installed adhesive anchors under combined stress by constructing 3D FEM model which can reproduce the experiment conducted in a previous research. A total of 13 specimens of varying parameters, i.e. anchor diameters, da, axial stress ratios, η and concrete strengths, Fc, are studied. Based on the analysis results, the influence of each parameter is investigated in terms of (1) shear force vs. relative horizontal displacement relationship, (2) curvature distribution of anchor bolts, (3) Mises stress distribution in anchor bolts, (4) damage states in concrete and (5) minimum principal stress distribution in concrete. In Chapter 2, the outline of the experiment and the details of the specimen parameters which are the subject of the analysis are introduced. In Chapter 3, the outline of the analysis model is described. The concrete, grout and anchor bolts are modeled by hexahedral elements (eight-node isoperimetric elements). The epoxy resin between the concrete and anchor bolts was modeled by joint elements (eight-node isoperimetric joint element) with thickness. Furthermore, depending on the interface properties, zero-length joint element are applied to model the bonding properties between different materials. The analysis results of the shear force versus relative horizontal displacement relationship show generally good agreement with the experimental results. For the specimens subjected to combined shear and tensile force, the following phenomena are observed. (1) The maximum curvature of the anchor bolt occurs at 2da (where da is the diameter of the anchor bolt) depth from the joint surface on the concrete side and 1da depth on the grout side. When the relative horizontal displacement reaches 2.0 mm, a total length of 5da is yielded in the anchor bolt: 3da on the concrete side and 2da on the grout side. (2) The Mises stress of the anchor bolt on the tensile side increases when the axial stress ratio increases. In this condition, the anchor bolt yields earlier due to the tensile stress and therefore the shear stress decreases in the cross-section of the anchor bolt. (3) In the specimens subjected to both shear and tensile force, cracks occur in the concrete due to dowel deformation and tensile stress. Meanwhile, the damage of the concrete increases when the axial stress ratio increases. (4) When the anchor diameter and the concrete strength increase, the bearing stress of the concrete also increases, and the concrete is compressed and softened in a wider range. (5) The maximum value of the minimum principal stress increases as the concrete strength and the axial stress ratio increase.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_79_link_17":{"attribute_name":"出版者版へのリンク","attribute_value_mlt":[{"subitem_link_text":"10.3130/aijs.83.1307","subitem_link_url":"https://doi.org/10.3130/aijs.83.1307"}]},"item_79_link_5":{"attribute_name":"室蘭工業大学研究者データベースへのリンク","attribute_value_mlt":[{"subitem_link_text":"髙瀬
