Finite Element Assessment Of The Effects Of Seismic Loading Rate On Soil Liquefaction, Radu Popescu

Architectural Engineering

The influence of frequency content of seismic excitation on the extent and pattern of pore-water pressure build-up in saturated soil deposits is addressed. Seismic acceleration time histories are generated as uniformly modulated nonstationary stochastic processes, in accordance with prescribed response spectra and prescribed modulating functions. Based on numerical examples, it is shown that the interplay between the frequency content of seismic excitation and the dynamic characteristics of the soil system and their evolution during and after the earthquake have important implications on the dynamic response.Key words: seismic motion, frequency content, finite elements, soil dynamics.

Bridge Lifetime System Reliability Under Multiple Limit States, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

A system reliability approach to minimizing the life-cycle cost of a deteriorating structure offers significant advantages such as a rational assessment of the assumed risk of failure, and an understanding of the importance and contribution of individual components to the overall reliability of the structure. The reliability of a structural system as a whole is the measure of its overall performance. This measure has to include both ultimate and serviceability limit states. A system model of a structure traditionally consists of a series-parallel combination of strength-based component limit states. Serviceability limit states however, can play a tremendously important role in …

Minimim Expected Cost-Oriented Optimal Maintenance Planning For Deteriorating Structures: Application To Concrete Bridge Decks, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

Civil engineering structures are designed to serve the public and often must perform safely for decades. No matter how well they are designed, all civil engineering structures will deteriorate over time and lifetime maintenance expenses represent a substantial portion of the total lifetime cost of most structures. It is difficult to make a reliable prediction of this cost when the future is unknown and structural deterioration and behavior are assumed from a mathematical model or previous experience. An optimal maintenance program is the key to making appropriate decisions at the right time to minimize cost and maintain an appropriate level …

Msrdc And Mumbai-Pune Expressway: A Sustainable Model For Privatising Construction Of Physical Infrastructure?, Hemalata C. Dandekar, Sulakshana Mahajan

City and Regional Planning

This case study of the Mumbai-Pune Expressway points out that delivery of infrastructure like road and highways, especially mega projects, totally through the private sector is currently difficult. In the absence of such private sector capacity to take on this responsibility, the role has been creatively shouldered by the Maharashtra government by forming and supporting a road development corporation - carved out of its public works department in its primary mission, the building of essential projects in a timely fashion. The experience of the Mumbai-Pune Expressway indicates that the public sector, freed of political intervention and outdated organisational structure and …

The Legacy Of Modern Urbanism In Brazil: Paradigm Turned Reality Or Unfinished Project?, Vicente Del Rio, Haroldo Gallo

City and Regional Planning

The Modern Movement ideals of transformation and progress coincided with the national spirit and zeitgeist of the 1930s Estado Novo in Brazil. Despite a persistent conflict between distinct urbanist views a progressive approach of urbanism became eventually predominant. Its strong impact on urbanist manifestations reached its climax with the construction of Brasilia. This paper explores some negative aspects of the modern legacy in Brazilian urbanism, but by acknowledging that Modern Movement ideals helped to establish a great sense of social consciousness and promoted a common aim, also the creation of a particular identity is recognized. By strengthening local elements of …

An Optimized Lifetime Reliability-Based Inspection Program For Deteriorating Structures, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

No matter how well they are designed, all civil engineering structures will deteriorate over time and a program of lifetime inspection, maintenance and repair represents a substantial portion of the total lifetime cost of most structures. An optimized inspection program is the key to making appropriate repairs at the right time to minimize cost and maintain an appropriate level of safety in a structure. When a visual inspection will not provide the necessary level of information, some other non-destructive evaluation method is often needed. This study summarizes a methodology for optimizing the timing, the frequency, and the type of inspection …

The proposed approach to the problem of lifetime bridge maintenance is shown to be a viable method for optimizing inspection and repair investments …

Repair Optimization Of Highway Bridges Using System Reliability Approach, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

As reliability based methods gain increased acceptance, there is greater opportunity to use scarce resources more efficiently while maintaining a prescribed level of reliability of a structure throughout its service life. The goal is to provide management decisions that will balance lifetime system reliability and expected life-cycle cost in an optimal manner. This study proposes a system reliability approach for optimizing the lifetime repair strategy for highway bridges. The approach is demonstrated using an existing Colorado State highway bridge. The bridge is modeled as a series-parallel combination of failure modes, and the reliability of the overall bridge system is computed …

A Quantitative Method For Estimating Probable Public Costs Of Hurricanes, Michael R. Boswell, Robert E. Deyle, Richard A. Smith, E. Jay Baker

City and Regional Planning

A method is presented for estimating probable public costs resulting from damage caused by hurricanes, measured as local government expenditures approved for reimbursement under the Stafford Act Section 406 Public Assistance Program. The method employs a multivariate model developed through multiple regression analysis of an array of independent variables that measure meteorological, socioeconomic, and physical conditions related to the landfall of hurricanes within a local government jurisdiction. From the regression analysis we chose a log–log (base 10) model that explains 74% of the variance in the expenditure data using population and wind speed as predictors. We illustrate application of the …

Sustainable Community Planning: Lessons From The Netherlands, Margot Mcdonald

Architecture

In 1990, the Dutch Government adopted a national plan to develop integrated and comprehensive policies that would respond on a national, regional, and local level to the need for improved environmental quality for the welfare of current and future generations. The program, called the National Environmental Policy Plan (NEPP), represented a bold effort to develop cooperation and shared responsibility between the public and private sectors setting goals for reduced energy consumption, resource utilization, and improved environmental quality including the reduction of SO₂, NO_x, and CO₂ emissions. This paper reports on key elements of the NEPP …

Reliability Of Reinforced Concrete Girders Under Corrosion Attack, Dan M. Frangopol, Kai-Yung Lin, Allen C. Estes

Architectural Engineering

Corrosion of reinforcement is a major problem affecting a large number of reinforced concrete structures. At present, most reliability-based design studies of reinforced concrete structures do not consider the effects of corrosion. In this paper, we present a reliability-based approach to the design of reinforced concrete bridge girders that are under corrosion attack. Both reserve and residual reliability constraints are satisfied. The approach is based on the American Association of State Highway and Transportation Officials (AASHTO) standard specifications for highway bridges and on data of chloride corrosion of steel in concrete. First, the effects of corrosion on both moment and …
