鉛直荷重下単層ラチスドームの静的および動的応答における弾塑性挙動の比較

摘要

This paper focuses on the elasto-plastic behavior of static and dynamic responses for single layer lattice domes, which are subjected to vertical loads. The purpose is to make clear the relationship between seismic responses and static responses from the view point of input strain energy properties after and before yielding, and to estimate bearable seismic levels with the information of static elasto -plastic behaviors. The static response compared is the relationships between equivalent velocities of strain energies and displacements. The dynamic response compared is that between earthquake input acceleration PGA and equivalent velocities of strain energies.%半開角と固定荷重をパラメータとした単層ラチスドームの鉛直荷重に対する静的応答（Fig.l4(a))と動的応答（Fig.l4(b))の関係に ついて比較考察した。また得られた結果から限界指標に至る地動加 速度PGAの推定を試みた。
