Sinopsis

Taiwan, situated in the Pacific seismic zone, experiences frequent seismic activity, making earthquake-resistant building design a crucial concern. The devastating Chi-Chi Earthquake of September 21, 1999, with a magnitude of 7.3, caused extensive damage, leading to the collapse of numerous buildings, including 43 compulsory school buildings. The disaster underscored the need for improved seismic evaluation methods to enhance structural resilience and protect human lives, especially in critical infrastructure like schools.

Structural failures, particularly in columns, were identified as a primary cause of building collapse. Three types of column failures were observed: flexural failure, shear failure, and a combination of both. These failures contributed significantly to the destruction of buildings during the earthquake. Given the vital role of schools not only as educational institutions but also as emergency shelters, their seismic performance must be thoroughly assessed and reinforced.

This book focuses on the seismic performance evaluation of an elementary school in northern Taiwan. The school consists of multiple adjacent buildings with insufficient spacing, increasing the risk of pounding damage during major earthquakes. Using ETABS 2015 software, the book employs the Capacity-Spectrum Method (ATC-40) and pushover analysis to evaluate the building’s resistance. The analysis considers various loading conditions, including gravity and lateral loads based on ASCE 7-10 standards.

Furthermore, this book compares seismic performance through dynamic analysis and time history simulations under different Peak Ground Acceleration (PGA) levels. The results guide retrofitting priorities, ensuring that existing school buildings meet safety standards. The book highlights the importance of seismic evaluation and retrofitting strategies to safeguard students and communities in earthquake-prone regions.
