碩士 === 逢甲大學 === 土木工程學系 === 105 === Abstract Currently,the earthquake resistant design of buildings are mostly conducted by structural or related technicians. However, these technicians are often unaware of the fact that shear bandings is the major effect of tectonic earthquake,whereas vibrations is the minor effect. Therefore, even if the design is in accordance with the Earthquake Resistant Design Specifications of Buildings, it only fulfills the demand created by the minor effect and totally ignores the demand brought about by the major effect. Under the guidance of the above-mentioned Earthquake Resistant Design Specifications of Buildings, most of the building tilt damage is derived from tectonic earthquake. On top of that, the assessment for the cause of building tilt damage after earthquake is often carried out without considering the major effect of tectonic earthquake, making it difficult to identify the major cause of the disaster. In this study, the author utilized a structural analysis model, which not only considers the floors of buildings above ground as typical structural or related technicians would use, but also takes into account basement, basement walls, basement wall supporting soil, foundation and foundation supporting soil. Moreover, the 3D dynamic analysis of buildings was conducted in this study by using an acceleration time history recorded during the 2016 MeiNong earthquake in Taiwan. The results of analysis showed that the amendment of the Earthquake Resistant Design Specifications of Buildings, the earthquake resistant design of buildings, and the identification of the cause for building tilt damage after earthquake should be carried out with a comprehensive structural analysis model which considers not only the minor, but also the major effects of tectonic earthquake in order to ensure the stability of buildings during tectonic earthquake and figure out the major cause to the building tilt damage.
