Available in PDF, EPUB and Kindle. Book excerpt: This dissertation develops a new concept for performance-based monitoring (PBM) of instrumented buildings subjected to earthquakes. This concept is achieved by simultaneously combining and advancing existing knowledge from structural mechanics, signal processing, and performance-based earthquake engineering paradigms. The PBM concept consists of 1) optimal sensor placement, 2) dynamic response reconstruction, 3) damage estimation, and 4) loss analysis. Within the proposed concept, the main theoretical contribution is the derivation of a nonlinear model-based observer (NMBO) for state estimation in nonlinear structural systems. The NMBO employs an efficient iterative algorithm to combine a nonlinear model and limited noise-contaminated response measurements to estimate the complete nonlinear dynamic response of the structural system of interest, in the particular case of this research, a building subject to an earthquake. The main advantage of the proposed observer over existing nonlinear recursive state estimators is that it is specifically designed to be physically realizable as a nonlinear structural model. This results in many desirable properties, such as improved stability and efficiency. Additionally, a practical methodology is presented to implement the proposed PBM concept in the case of instrumented steel, wood-frame, and reinforced concrete buildings as the three main types of structural systems used for construction in the United States. The proposed methodology is validated using three case studies of experimental and real-world large-scale instrumented buildings. The first case study is an extensively instrumented six-story wood frame building tested in a series of full-scale seismic tests in the final phase of the NEESWood project at the E-Defense facility in Japan. The second case study is a 6-story steel moment resisting frame building located in Burbank, CA, and uses the recorded acceleration data from the 1991 Sierra Madre and 1994 Northridge earthquakes. The third case is a seven-story reinforced concrete structure in Van Nuys, CA, which was severely damaged during the 1994 Northridge earthquake.The results presented in this dissertation constitute the most accurate and the highest resolution seismic response and damage measure estimates obtained for instrumented buildings. The proposed PBM concept will help structural engineers make more informed and swift decisions regarding post-earthquake assessment of critical instrumented building structures, thus improving earthquake resiliency of seismic-prone communities.

This book was released on 1997 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Jan. 17, 1995, Hyogoken-Nanbu Earthquake was one of the worst disasters to hit Japan in almost half a century. It has been compared in its impact to the great Kanto (Tokyo) Earthquake of 1923. The Kobe-Osaka region held many similarities in its geologic and tectonic setting to many areas along the West Coast, and possibly, other areas of the U.S. A geotechnical reconnaissance to identify the relevant problems and issues was organized. This report provides a timely, first-hand overview of the type and extent of the geotechnical aspects of the damage.

Available in PDF, EPUB and Kindle. Book excerpt: The collapse of the Cypress Street Viaduct during the 1989 Loma Prieta earthquake emphasized the vulnerability of elevated freeway bridge structures. A part of the joint Caltrans and University of California at Berkeley research project, initiated after the earthquake, focused on the outrigger knee joint systems found in bents of elevated freeway bridges. The investigation had two principal goals: to evaluate the behavior of the existing outrigger knee joint systems under a combined transverse and longitudinal loading and to devise and experimentally verify strategies for seismic upgrading of existing outrigger knee joints. The experiments on two half-scale as-built models confirmed the poor performance of existing outrigger knee joint systems observed after the earthquake. Two seismic upgrading strategies, a "ductile" and a "strong" strategy, were proposed and tested on prototype specimens. The "strong" strategy was chosen for the final seismic upgrade design. The variation of this strategy using a steel jacket, was recommended in the seismic upgrade design guidelines.
