Outline of Final Research Achievements

To estimate the seismic safety limit of non-structural elements and attachment part of building equipment, and to develop a method to reinforce them, embedded anchor bolt and chemical anchor were chosen as subjects of this research. Both of embedded anchor bolt and chemical anchor had not be clarified ultimate behaviors caused by complicated seismic response of non-structural elements and attachment part of building equipment.
Under a certain condition, multi-axial cyclic loading tests were conducted on the attachment parts, to clarify the ultimate behaviors and maximum strength. Through the experiments, the seismic safety limits were estimated. Based on the results of the experiments, basic information needed for developing the reinforcement method were obtained.
