DEVELOPMENT AND PERFORMANCE EVALUATION / DESIGN GUIDELINE OF DAMAGE SELF-CONTROL STRUCTURES WITH ROTATIONAL FOUNDATION DUE TO UPLIFT AT PILE HEADS

在结构发生损伤之前，由于桩头纵向钢筋的伸长而引起基础旋转的新型结构已经发展起来。地震能量被杆的伸长所耗散，因此结构几乎没有受到破坏。根据这种旋转结构的实验和分析结果，还制定了抗震设计指南、结构细节手册和设计/施工手册。

The new type of structures whose foundation rotates due to the elongation of longitudinal reinforcing bars at the pile heads prior to occurrence of damages in structures has been developed. The seismic energy is dissipated by that elongation of the bars, so the structures scarcely suffer damage. The seismic design guideline, the manual for structural details and design /construction manuals have been also developed,based on the experimental and analytical results of this rotational structures.
