| Summary |
In seismic design of general architectural structures, earthquake is considered as horizontal static loads. In several studies, however, it has been pointed that vertical vibration can be observed in seismic response of large-spanned roof structures such as frame-supported membrane structures. If seismic design of large-spanned structures is performed by using only horizontal static loads, structures may not have enough strength for earthquake. For above mentioned problem, Takeuchi et. al. proposed a seismic response evaluation method. In this method, horizontal and vertical accelerations were considered, and they were amplified along ratio of fundamental frequencies of roof and structure. In this paper, the seismic response evaluation method is applied to a cylindrical frame-supported membrane structure. Response spectrum analysis is also performed, and the results are compared. It is discussed that seismic response of frame-supported membrane structures can be accurately evaluated by using the method
