NUMERICAL VALIDATION OF A PROPOSED SELECTION METHOD OF STRUCTURAL SUB-MEMBERS FOR PARTITION WALLS MADE OF STACKED ALC-PANELS

Abstract

In the Great East Japan Earthquake, many large-scale partition walls made of stacked ALC(AAC) panels were damaged. Those walls are constructed with intermediate sub-beams. Strong motion observations and shaking table tests by authors clarified that large vibrations in out-of-plane direction can occur in those walls during earthquakes. A countermeasure to suppress vibrations is to select stiff members enough to keep high frequencies. In the previous paper, a practical selection method of structural sub-members as in a tabular form was proposed. In this paper, validations of the proposed selection method are discussed by comparing the results by FEM.
