Early Age Strength Detection for In-situ Concrete
In recent years it has become increasingly beneficial to know the quality of concrete as soon as possible after it has been placed. This is especially true for high-rise concrete buildings...
Fast-Track Concrete Paving
Well known for its corn production, the State of Iowa has been seeding a new product for the past several years. 'Fast Track' concrete has grown along the edge...
Early Opening of Concrete Pavements to Traffic
Current practice for opening slab replacements and full-depth repairs to traffic ranges widely from 2 hours to several days. A rational and simple procedure is urgently needed for determining...
Development of Analytical Models for Reinforced Concrete
A computer program called WCOMR was developed to analyze the characteristics of RC walls subjected to reversed cyclic loading. The WCOMR comprises RC element idealization described by...
Analysis of Slender Prestressed Concrete Columns
This paper briefly describes an analytical model developed to study slenderness effects in prestressed concrete columns and walls and predict the characteristics of such members over a...
Guidelines for Application of FEM to RC Design
In this paper, the main contents of the guidelines for the application of FEM analysis to the design of reinforced concrete structures are presented. The guidelines were published by the...
Application Examples of FEM to Concrete Structures
The paper illustrates the practical application of the FEM by means of examples for plain/reinforced/prestressed concrete structures. These examples, including both global and local analyses...
Macroscopic Models for R/C Shear Walls
In this paper, the discussion is mainly focused on four macroscopic models, recently proposed by Japanese researchers, for predicting ultimate strength of reinforced concrete (R/C) shear...
Verification of Macroscopic Models or RC Walls by FEM
Several macroscopic models based on the limit analysis have been proposed for obtaining the ultimate strength of reinforced concrete shear walls in Japan. When using these models, it is...
Parametric Analyses of RC Shear Walls by FEM
In this paper, nonlinear behavior of reinforced concrete shear walls is studied by using the finite element analysis. We applied numerical analyses to a wide range of parameters, such...
Issues in the Validation of Probabilistic Methods
Probabilistic models are being used increasingly in safety assessments and regulatory decision-making. There is a need to relate the risks computed using these models to service data in...
Applications of Probability for Structural Analysis in the Nuclear Industry
Probabilistic techniques are being used as part of structural analysis in the nuclear industry to investigate various safety-related issues. Historically nuclear power plants have been...
Stress Analysis of the Liner and Liner Anchorage System Near Penetrations in a Reinforced Concrete Reactor Containment
An overpressurization experiment was conducted on a scale-model of a reinforced concrete containment building. The test was terminated when tears formed in the steel liner. Virtually all...
Seismic Response of Multistory Building Structures With Flexible Floor Diaphragms
An efficient model for three-dimensional analysis of multistory structures with flexible floor diaphragms is proposed in this paper. Three-dimensional analysis of a building structure...
Status of Structural Engineering Research
Problems and opportunities for structural engineering research are being addressed in a study by the ASCE Structural Division Task Committee on Structural Engineering Research Needs/Funding....
The Civil Engineering Foundation ? A New Beginning
The United States' construction industry is ailing, experiencing a decline that rivals that of the auto and other US manufacturing industries. How the decline is to be halted...
Toward an LRFD-Based AASHTO Bridge Specification
During the 1987 AASHTO Bridge Committee Meeting, recommendations from NCHRP Project 20-7/31 regarding the development of a probability-based LRFD bridge specification were accepted. NCHRP...
Evaluation of Bridge Safety and Remaining Life
In developed countries, the emphasis on the infrastructure is changing from new construction to the safe maintenance of existing structures. Highway bridges represent an excellent example...
LRFD: Progress for Engineers and the Wood Industry
The LRFD for Wood project represents a milestone for the industry. The significance of the project goes far beyond merely switching formats in design equations. The project signifies both...
Impact of Errors on Safety During Construction
The construction process involves a number of procedures which integrate together from the first intention of building the project to the end of the structural cycle. In this study, a...
