| dc.description.abstract | This dissertation presents an investigation on the earthquake behavior of Chilean “fishbone” type shear-wall buildings that were damaged during the February 27, 2010 Great Maule earthquake (Mw=8.8). It makes a case that most of the damage took place in newer high rise buildings, caused in part by the use of ever slenderer walls in progressively taller buildings, and more importantly, by brittle failure in the walls at lower elevations due to high compressive loads in buildings with more than ten stories. Close to 2% of the reinforced concrete buildings taller than 9 stories in Chile underwent substantial damage during the earthquake. Field observations have also revealed a high incidence of non-ductile (i.e. brittle) bending and compression failures of reinforced concrete shear walls which are typically found in the lower stories and first basements. Considering that other buildings with similar structural concepts performed rather well during this earthquake, it behooves to elucidate by comparative analysis some of the reasons underlying one type of behavior or the other.The typical Chilean “fish-bone” building behaved rather very well during the large, previous 1985 Chile earthquake, and one of the main reasons for this behavior may have been their conservative design, as reflected in their large amount of total shear-wall to floor area of, say, 5-6%. Considering that construction practices and design precepts have evolved significantly in Chile since 1985, one of the goals of this research is to discern how those design practices may have changed and thus influenced the seismic performance of tall buildings. Although in a large majority RC buildings performed well during 2010 Maule Earthquake, this research aims to understand the observed damaged and earthquake behavior of these structures. To reach this goal, this dissertation is divided in three phases: (i) description of RC shear wall buildings damaged during 2010 Chile earthquake based on the analysis of data gathered in the field; (ii) inelastic analysis and response of RC walls damaged during 2010 earthquake by means of pushover analysis of a single wall; and (iii) threedimensional inelastic dynamic analysis and response of a real RC building based on a detailed finite element model, with the goal of predicting damage using real earthquake records. | |
