He said, " that night we pitched a tent out in our backyard and we slept in the tent because we were afraid the house wouldn t stand up. " he said, " that totally changed my worldview and my perception of life because up until that time, i had the impression or the thought that adults were in control and they had security and they gave me security. during the earthquake i saw people panic and the panic was such that people were clearly out of control
他說：當晚我們就在後院搭起帳篷，在那裡過夜，因為恐怕房子會倒塌，那件事完全改變了我的世界觀，以及我對人生的看法，因為在那之前，我有一個印象或想法，總覺得大人能掌控一切，他們有安全感，他們也能給我安全感，但地震發生后，我看到人們的惶恐，惶恐得失控，八歲的孩子，看見大人們這樣的失控，我發現自己感到極不安全，對一切都沒有把握。The mechanic character, destroying pattern, the ductile and dissipation energy capacity of this composite structure under the earthquake have been clarified. the stiffness degradation, natural frequency, damping ratio of this structural system with the development of intensity of earthquake have also been investigated. with consideration of the top displacement, drift of story and micro - strain of longitude steel bars, the equivalent shell wall method has been presented in order to simplify the design of such type structure
通過試驗，掌握了該結構體系在水平地震荷載作用下的受力特點、變形與耗能性能、結構的破壞形態等力學指標：得到了結構在不同地震烈度條件下的剛度變化、自振頻率、阻尼比等動力特性；綜合結構的頂點位移、層間轉角以及鋼筋的微應變，提出了適合於該結構體系簡化設計的「等效剪力墻法」 。Based on 266 strong ground motion records from 15 earthquakes in america, an attenuation relationship was used to relate energy spectra to earthquake magnitude, source - to - site distance, and site class. the purpose of this study is to make a foundation of energy - based design and seismic hazard analysis. the main achievements of this study could be summarized as follows : 1
本文的主要工作就是利用所掌握的地震動記錄，採用兩步回歸法對地震動的各種能量參數進行回歸分析，找出地震動的能量參數隨震級、距離等參數的衰減關系，為基於能量的方法能夠應用到抗震設計及震害評估等實際工程中奠定基礎。
