Tensile Fracture and Fatigue of Cement Stabilized Soil
Portland cement stabilized soil is widely used as a base material for roads, airfields, and similar structures. Cracking in this material is studied using fracture mechanics concepts....

The American Association of Cost Engineers Claims Project
Construction contract disputes, or dressed in their popular nomenclature, 'contract claims', have become an established aspect of the non-residential construction...

Building Condition Assessment�An Owner's Perspective
The Port Authority of New York and New Jersey has recently instituted a program to inspect all of its buildings structures to insure structural integrity and public safety and to provide...

Evaluation and Modernization of Veterans Administration Facilitaties
This paper discusses two examples showing in detail that procedures for building assessment require much consideration for engineers' programming and must be properly specified...

Changing Priorities in UK Construction Research
This paper addresses two types of situations to contend with in building assessment: aging structures all built at about the same time and to standards no longer acceptable, and newer...

Research Needs for Extant Iron and Steel Buildings
A brief review of iron- and steel-making processes is background for the development of shapes and codes. Sources of information for the condition assessment of iron and steel buildings...

Masonry Rehabilitation: Practice and Research
The rehabilitation of masonry buildings is a major construction activity in the United States. The available techniques and evaluation methodologies are limited to visual investigation...

Structural Integrity Assessment of the Flexible 870 Advanced Design Bus
The Grumman Flxible 870, a lightweight advanced design urban bus, entered service in Atlanta, GA in 1978, and some 2,800 of these buses were in service nationwide by 1980. In the autumn...

Prestress and Cracking Problems in Concrete Structural Components of an Elevated Rail Transit Guideway System
In 1983 the Department of Transportation evaluated the quality of construction of selected structural components on the Dade County Transportation Administration METRORAIL elevated guideways....

Damage Tolerance Assessment of Commercial Airframes
The regulatory authorities now require that commercial transport aircraft structural design be based on a damage tolerance philosophy. A brief history of the development of the regulations...

Tension-Compression Test of a Concrete Specimen Via a Structure Damage Theory
The concrete sample is assumed to consist of a large number of aggregates and cement paste. Their material properties are assumed to be perfectly elastic. The effective elastic property...

Effect of Voids on Creep Rate and Strength
The classic macroscopic Kachanov-Rabotnov model of material damage due to voids is reviewed. Detailed analyses of bulk mechanical properties of dilutely voided materials with certain,...

Constitutive Theories for Solids with Defective Microstructure
The nonlinear mechanical response of solids is a macroscopic manifestation of the irreversible changes in its microstructure. The most common modes of the irreversible microstructural...

Continuum Modeling of Periodic Truss Structures
Procedures for deriving equivalent stiffnesses for an extended Timoshenko beam used to represent truss beams are presented. A typical substructure of a truss is used to calculate these...

Continuum Modeling of Discrete Structures with Geometric Nonlinearities
The modeling of geometrically non-linear discrete structures by an equivalent continuum is presented. The discrete-continuum analogy is developed by first isolating a unit cell of the...

General Continuum Models for Discrete Structures
New knowledge is presented about the structural behavior of a variety of large repetitive lattice configurations of the type appropriate for utilization in cosmic space. Focus is placed...

Use of Computer Graphics in the Analysis of Large Space Structures
This paper illustrates how interactive computer graphics can provide a useful tool in setting up analytical models of structural latticeworks comprised of large numbers of degrees of freedom...

Damage Detection in Periodic Structures
Nondestructive damage detection in periodic structures using continuum analogues of the discrete structure is studied. Algebraic equations relating changes in eigenfrequencies to the fractional...

Small Strain Measurements Using Triaxial Apparatus
This paper presents a detailed testing methodology which can be used to determine the cyclic properties of soils at very small strains using triaxial apparatus. A discussion of specific...

Uplift Behavior of Shallow Soil Anchors?An Overview
An overview is presented of the static uplift (tensile) behavior of shallow anchors used for foundations in soil. Basic anchor types are described, and their general installation and behavioral...
