Earthquake Resistance of High-Rise Systems: Digests of Case Studies of Tall Buildings Damaged in Earthquakes

摘要

The report contains a collection of digests of detailed case-studies on tall buildings damaged in earthquakes and a preliminary assessment of the available data. Each digest identifies site, ground motion, soil conditions: high-rise systems (structural, architectural, mechanical); design and construction related data as year of construction, governing code, design assumptions and construction practices; damage; cause for observed performance and failures, and recommendations or lessons learned. The digest portion of the report is followed by a presentation of classification schemes for high-rise systems, earthquake, and damage, and a preliminary assessment of data. The investigated parameters material (steel versus concrete), tallness (high-rise versus medium-rise), configuration (regular versus irregular), and structural system (other versus moment-resisting frames) were found to affect earthquake damage in tall buildings in this order of importance.
