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...
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...
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...
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...
Uplift Capacity of Shallow Offshore Foundations
Soil failure under upward loading is investigated by experimental laboratory tests. The problem of uplift capacity is considered in terms of effective stresses in soil skeleton and pore...
Restoring the Capitol's West Front
After 25 years of debate, preservation (rather than extension) of the West Front of the U.S. Capitol building in Washington, D.C. has begun. A network of stainless steel rods is being...
New Cables for Old
In an eingineering first, the main suspension cables will be replaced on New York City's Williamsburg Bridge without closing it to traffic at any time. According to the design...
Hurricane Alicia
One Year Later
In the pre-dawn hours of August 28, 2983, Hurricane Alicia ripped its way ashore at the western tip of Galveston Island and moved northward to the Greater Houston area. This storm caused...
Composite and Mixed Construction
Steel and reinforced concrete are frequently combined in composite or mixed structural systems. This combination generally results isn greater economy and safety than could be achieved...
Coastal Zone '85
Coastal Zone '85 was a multidisciplinary conference for professionals, interested citizens, and decision-makers to exchange information and views. Coastal zone management...
The Outardes 2 Concrete-Faced Rockfill Dam
The main dam of the Outardes 2 development consists of a rockfill embankment, built against an old water-retaining structure, and faced with an upstream concrete membrane. The interface...
