Autor: Kurata, Masahiro, Suzuki, Akiko, Minegishi, Kaede, Nakashima, Masayoshi

Publikováno v: 日本建築学会構造系論文集. 80(713):1045-1053

This paper presents a method of evaluating local damage in steel beam-column connections using dynamic strain responses measured under ambient vibrations. In the proposed method, inner-force distribution in steel beam-column connection was estimated

鉄塔・電線連成系の実機振動試験データによる動的応答解析コードの精度検証

Publikováno v: 都市・建築学研究. 22:57-64

Generally, a transmission tower is designed statically based on Japanese civil standard: Design Standard on Structures for Transmission, JEC127-(1979). However a special tower, e.g. very high tower and a tower under gusty wind, is designed dynamicall

Vibration Test of a Transmission Tower with Hanging Jumper Beam Focusing on the Associated Vibration of its Members

Publikováno v: 都市・建築学研究. 14:87-94

A hanging jumper beam of a transmission tower is adopted as a countermeasure against a short fault of jumper conductors under strong winds. However it is thought that the hanging jumper beam may cause the vibration of transmission tower members due t

A Cable-less System for Wind Response Measurement of a Structure : Quality Evaluation by a Vibration Test of a Transmission Tower

Publikováno v: 都市・建築学研究. 13:33-40

The vibration measurement of a structure requires considerable labor for installing not a few signal cables in the structure, and it is difficult to deal quickly with the unexpected change of circumstances like the change of a typhoon path. It is obv

Measurement technology of micro-vibration transmission: Researches on space structural technology

Autor: Uchida, Hideki, Shimizu, Ryuzo, Endo, Tatsuya, Komatsu, Keiji

Pointing Accuracy of sensors and stability of attitude control of spacecraft are influenced by micro-vibration transmitted from components, for example, reaction wheels and coolers, which are regarded as internal disturbance sources. Such micro-vibra
