Abstract: Between 2008 and 2011 members of the Concrete Coalition completed numerous building inventories of California cities to assemble a database of California pre-1980 concrete buildings. Inventory collectors used a variety of data sources ranging from county assessors files to Sanborn maps and satellite images. Sidewalk surveys were used to corroborate data collected from multiple sources, and a regression model was developed to extrapolate data to cities where detailed inventory collection was not possible. Lessons drawn from inventories of three cities – Alameda, Los Angeles, and San Francisco – indicate that no single approach can be recommended, but instead the approach depends on many things including city size, building stock, available budget, available data, and availability and experience of human resources. Regardless of approach, inventory data is a valuable resource for developing loss estimates and policy recommendations.
Abstract: The George E. Brown, Jr. Network for Earthquake Engineering Simulation (NEES) coordinates a geographically distributed Research Experience for Undergraduates (REU) program with up to 30 students placed at five to eight research sites each summer. With only two to four students at each site, creating a sense of cohort among these 30 geographically distributed students can be difficult. One challenge is providing opportunities for all of the students to interact in ways that support each other’s research experience. In an attempt to maximize student learning and personal growth, the program coordinators have leveraged NEEShub, the cyberinfrastructure that interconnects the 14 NEES research sites, to engage students in professional development activities and peer-to-peer interaction. The REU program uses a combination of face-to-face and technology mediated interactions. Cyberinfrastructure tools to support interaction between cohorts at the different sites include a course management system (Moodle embedded in NEEShub), WebEx video conferencing, and a 3D virtual world called QuakeQuest. For the online interaction to be most effective, students 1) need to understand why they are using the tools, and 2) be coached in how to critique each other’s work and contribute to threaded discussions.
Abstract: Today’s engineers must be more than just technically competent. To be successful in our increasingly global economy in which teamwork and interdisciplinary interaction are the norm, engineers must have excellent communication skills. In recognition of industry needs, the San José State University College of Engineering redesigned its technical communication course to ensure that students graduate with writing and speaking skills that will transfer readily to their career needs and the global arena. The course aims to motivate students through exploring topics that are meaningful to them and using communication formats that they will see in the workplace. Combining technical communication with study of the environment broadens the course to meet multiple Accreditation Board of Engineering and Technology outcomes. This paper describes the course goals, organization, management, selected assignments, and assessment. Assessment data indicate that at the end of the semester students, on average, have gained between 0.8 and 1.1 points on a 12-point evaluation rubric and have gained an appreciation of the unique characteristics of and need for technical writing.
Abstract: The goal of the document is to provide guidance and information to civil engineers and science museum professionals so that they can collaborate to create more exhibits related to civil engineering. The report explains the functions of civil engineers and science museums and then explores the benefits of collaboration. It describes numerous succesful civil engineering exhibits and then discusses the tools to develop a successful exhibit.
Abstract: Outcomes assessment often becomes a focus of attention as a response to accreditation requirements. But if the emphasis is short-term, it can produce crisis-mode frustrations that will be repeated each time accreditation rolls around. Increasingly, accreditation agencies are asking for evidence that program-level assessment is ongoing. This article summarizes steps taken at San Jose State University to develop systems that will ensure sustainable and ongoing assessment and program improvement activities.
Abstract: Although ABET Outcome 3b explicitly requires engineering graduates to demonstrate ?an ability to design experiments,? engineering curricula rely heavily on cookbook experiments, in which students simply follow a sequence of steps in the form of a recipe and arrive at a predetermined result. Cookbook experiments do not require design by the students and therefore do not draw upon the critical thinking skills that lead to deeper learning. Using a fairly general process to guide students in the design of experiments, the authors have developed an instructional rubric to both assess student mastery of the design steps and help students understand the goals and expectations of the process. Laboratory experiences in aerospace, civil, and chemical engineering have been re-designed to allow more student-directed and student-designed inquiries, and are being used to pilot the application of the rubric.
Abstract: Engineering faculty from San Jos? State University (SJSU) are participating in the project to both provide content knowledge for teacher professional development and to enhance undergraduate instruction in the SJSU College of Engineering through enriched pedagogy. Strategies for incorporating inquiry-based learning into the SJSU undergraduate and graduate engineering curricula have been explored in both lecture and lab courses.
Abstract: A multi-institutional collaborative project, investigating soil-foundation-structure-interaction (SFSI), is being used to demonstrate collaborative research using the George E. Brown Network for Earthquake Engineering Simulation (NEES). The research plan involves computational simulation models as well as testing of a scaled bridge and complementary shake table, static, centrifuge and field tests of scaled bridge components to develop improved models of SFSI. To achieve one of the goals of the project, i.e. synthesize research and educational activities, two educational modules are under development. The first module explores the nonlinear behavior of individual reinforced concrete bridge columns and the second explores the effect of soil modeling assumptions on the analysis of a bridge bent. Each of these modules integrates results of analytical studies and experimental data with structural analysis and design concepts currently taught in the senior year or master's degree, to help students understand the limitations of modeling assumptions that they make. This paper discusses the two educational modules and the benefits and challenges associated with integrating experimental research and curriculum development.
Abstract: The Enginering Handbook consists of 150 chapters on topics ranging from basic statics and circuits to bioinstrumentation, control systems, nanotechnology, image and signal processing.
Abstract: This textbook is for introductory courses in statics. It includes vector analysis of forces and moments, free body diagrams, equilibirum in two and three dimensions, distirbuted forces, centroids, hydrosatic pressure, friction, and analysis of trusses, frames and machines. In addition, one chapter is devoted to analyzing the load path for a bicycle and another to the load path of the Golden Gate Bridge.
Abstract: A research program has been developed to study soil-foundation-structure interaction using the NEES infrastructure. Complementary shaking table, centrifuge, field, and laboratory specimens have been designed and testing is scheduled to begin in the summer of 2004. Comprehensive computational models are also being developed to interpret the response of the individual experiments, relate the test specimen response to the performance of the prototype system, and understand the limitations of the boundary conditions inherent to each of the experiments.
Abstract: A database has been developed that documents performance of substation equipment in twelve California earthquakes. Equipment in the database is owned by Pacific Gas & Electric, Los Angeles Department of Water and Power, Southern California Edison and the California Department of Water Resources. The majority of data relates to equipment operating at 220/230 kV and 500 kV. The database is organized into an EXCEL 5.0 spreadsheet with 68 data fields describing earthquake location, ground motion, site location and conditions, equipment characteristics, performance of equipment, failure mode, and restoration time. Each record represents a single piece of damaged equipment or several pieces of similar undamaged equipment. The purpose of the database is to provide a basis for developing or improving equipment vulnerability functions.
Abstract: Considering the development of computers and information technology, the present reliability assessment concept and format of standards for structural steel design seem to be outmoded. With designers using probabilistic reliability assessment concepts, Monte Carlo techniques and databases as tools, a reconstruction of the present standards can be expected. This paper addresses one possible alternative for qualitative changes in design standards and corresponding reengineering of the entire reliability assessment procedure. This includes introducing a probability of failure as a measure of structural reliability, developing a new generation of “hybrid” standards (basic and secondary standards, databases and software mutually interconnected using information nets), expressing variable input data as histograms and using simulation techniques to analyze the complex probabilistic interrelationships between load effects, material properties, and other quantities affecting reliability. The significance of the transition from a deterministic to probabilistic “way of thinking” is emphasized in terms of both education and design practice.
Abstract: The paper summarizes the development of a geographic information system (GIS)-based regional loss estimation methodology for the United States funded as part of a four-and-one-half year project by the Ferderal Emergency Management Agency (FEMA) through the National Institute of Building Sciences (NIBS). The methodology incorporates state-of-the-art approaches for characterizing earth science hazards,estimaiting damage and losses to buildings and lifelines, estimating casualties, shelter requirements and economic losses, and data entry to support loss estimates.
Abstract: Simulation-Based Reliability Assessment for Structural Engineers provides an overview of the basic concepts in structural reliability and introduces an alternative based on direct Monte Carlo simulation techniques, on parameters-generated histograms, and on available personal computers. This approach is a powerful tool that allows (in accordance with the Limit States Design philosophy) one to explore the effect of variables and uncertainty on design decisions. It also discusses single- and multi-component load effects and explores combinations of such effects. Limiting values are defined and applied to reliability assessments with respect to carrying capacity and serviceability states. Examples that clearly illustrate the application of simulation techniques are provided, and the tremendous potential of these techniques for use in design is reviewed.
