摘要: 摘要
本文探討本省農會及碾米廠之大型穀倉儲槽受921集集大地震之倒塌及損壞評估,發現原有儲槽支承構架之斜撐耐震能力不足,產生側潰而導致整體構架解體。本文除進行倒塌原因分析外,並且提供改善現存以及未來興建之穀倉儲槽結構設計及耐震補強措施,避免爾後此類結構物再因地震而倒塌,降低業主損失。
Abstract
This thesis deals with the collapse analysis and damage evaluation of large granary tanks belonging to Taiwan Farmer's Association and private rice-husking factories during 1999 chi-chi earthquake.
From the field observations and model analysis, it is found that the bracing analysis of the original-type tank was damaged first.
It resulted in large lateral displacement of the supporting system and led to the whole structure collapsed.
Besides investigating the cause of granary tank collapse, the design suggestion for new granary tanks and the retrofit strategies for existing granary tanks are provided in this thesis to avoid collapsing of similar structures and lower the wealth loss for owner.
