Global Network Optimization for Pavement Management
In a state-wide pavement management system, the highway network can be divided into a number of road categories based on traffic level and geographical region. Network optimization analysis...
Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...
The Development of an Expert System Used in Preliminary Design of Concrete Bridges
The importance of the selection of the best design on the one hand and the available knowledge, on the other during the preliminary design process asks after a different kind of software...
Time-related Deflections of Cantilever Bridges
Many prestressed concrete bridges with spans between 100 and 160 m have been built in the Netherlands. The method of construction is the so-called in situ free cantilever construction....
An Artificial Neural Network Approach to Pavement Maintenance Decision Support System
An important component of any Pavement Maintenance Decision Support System (PMDSS) is the condition survey and rating procedures. Data obtained from these procedures are the primary basis...
Characteristics of the US Highway Bridge Population
Characteristics of US highway bridges are summarized, and conditions of national, regional, and state bridges are analyzed with respect to structural deficiency. The overall patterns in...
Seismic Analysis of Reinforced Concrete Building Using Finite-element Techniques
The response of a reinforced concrete building subjected to earthquake loading has been obtained on a personal computer using the finite-element code STARDYNE. For preliminary design,...
Developing an Object Based Planning System for Precast Concrete Building Structures
This paper presents the organization of an object based planning system for determining the preliminary costs, schedules and resources for precast concrete building structures. First,...
Macroelement Model for Shear Wall Analysis
An efficient modeling scheme for static and dynamic analysis of reinforced concrete shear walls in the inelastic range is presented. The macroelement model of the shear wall is composed...
The BS8110 CAL Program for Teaching RC Design
This paper describes the main features of RC-CAL, a computer-aided-learning courseware for reinforced concrete design to BS8110, the British Code of Practice. Results of an evaluation...
Pavement Treatment in Ohio Transportation System
This paper presents a modification of the original method in which the concept of fuzzy set theory is applied in the calculation of the PCR. Fuzzy numbers are introduced to represent those...
Rotating Crack Model and Fracture in a R/C Medium
In this study the potential of the development of cracks in the members of a reinforced concrete large panel structure is considered. The analysis is carried out using finite element modeling...
Integrating Computer Application for Pavement Management: A Case Study
This paper presents a case study of the process through which a relational database management system and stand-alone application programs are developed and integrated to form a comprehensive...
Deformations in Sand Layer During Pile Driving
This paper presents measurements of settlement and lateral soil movements in a medium dense to dense sand layer due to densification during driving of precast concrete piles. At one end...
The Control of Settlement Using Geogrids
The applicability of geogrids in reducing settlements has been investigated in the laboratory in two separate studies, in unpaved roads under cycled load applications, and as overlays...
Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...
Energy Dissipation for a RCC Stepped Spillway
A two-dimensional physical model study was used to quantify the kinetic energy dissipation of the steps in a roller compacted concrete (RCC) stepped spillway. The steps were effective...
