A New Alternative in Steel Construction?Partially Restrained Connections
Lack of formal training in methods as well as the lack of specific guidelines have limited the understanding and utilization of semi-rigid connection technology. A renewed interest in...
The Effect of Connection Flexibility on Steel Members and Frame Stability
With the advent of Load and Resistance Factor Design (LRFD) and the many existing moment-rotation curves for connections, the use of actual connection flexibility in the design process...
Failure Statistics Categorized by Cause and Generic Class
Failures can be classified into the three categories, ie. , SAFETY, FUNCTIONAL, and ANCILLARY. Within the causation definition, failures fall into five general areas: DESIGN DEFICIENCIES;...
Alternative Procedures for Investigating Failures
Failures of engineered structures continue to occur. This is despite rapid advances in engineering theory, new, more sophisticated methods of analysis, and streamlined techniques for preparing...
Learning from Failures
Modern technology and innovation have created a gap between what the design drawings predict with respect to safety and serviceability of a structure and the real safety and serviceability...
Learning from Failures: Procedural Changes in the Design and Construction Process to Reduce Failures
This paper first defines failures and their number and scope in the design and construction fields. It then presents the writer's opinion as to the cause of the failures and...
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....
Rigid Pavement Rehabilitation: Interstate 95?Duval County, Florida
Rehabilitation studies have been conducted on Interstate 95 in Duval County, Florida. The rigid, unreinforced pavements were constructed in the late 1950's and 1940's....
Better Design Documents Through Constructibility Review
The Corps of Engineers (Corps) improves the quality of design documents by an extensive program to review in-house and Architect/Engineer (A/E) designs. This review is composed of several...
Inspection Costs Versus the Benefits Derived
The following text describes the experiences of a small suburban municipality located in Middle Tennessee before, during and after a five-year program of comprehensive inspection and testing...
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...
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...
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...
Resistance of Shallow Inclined Anchors in Clay
Some recent laboratory model test results for the ultimate pullout resistance of a square anchor inclined at angles of 0, 20, 50, 75, and 90 degrees with respect to the horizontal have...
Transmission Tower Foundations in Weathered Rock
A case history is presented which discusses the siting, design and construction of the tower foundations for a transmission line in southwest Alaska. The project, completed in 1983, consists...
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...
Control of the Design Process
Gilbert/Commonwealth, Inc. (G/C) was the architect-engineer for the original design of the Florida Power Corporation (FPC) Crystal River Nuclear Plant, Unit 3 (CR3) and has been involved...
