Simulating Construction Operations by Microcomputer
Field operations on major construction projects involve complex interactions among construction equipment, materials and supplies, skilled craft resources, and technical and administrative...
Nine Years' Service with Deep Polymer Impregnation
A test installation of deep polymer impregnation was applied to a heavily traveled bridge deck in Bethlehem, Pennsylvania, in 1975. The deep polymer impregnation process involved drying...
Type C Fly Ash and Clay Stabilization
Because the soils onsite have a high swell potential, a 37 foot high retaining wall was designed with counterforts and was supported by pier foundations to limestone. In order to reduce...
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....
Soft Ground Tunneling of the Greenbelt Tunnels
Mergentime/Loram's contract for the construction of Section E-1d Greenbelt Route Tunnels includes construction of dual 1,770-foot tunnels in soft ground, a crossover structure,...
Construction of Mt. Baker Ridge Tunnel
Mt. Baker Ridge Tunnel is a large diameter soft ground highway tunnel constructed through sensitive over-consolidated silts and clays. Its large diameter necessitates the construction...
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...
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...
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,...
Aspects of Constant Volume Cyclic Simple Shear
Data from cyclic simple shear tests comprise the foundation on which rests most of the practical applications of theoretical soil dynamics. The importance of the test derived from two...
Multi-Directional Irregular Loading Tests on Sand
In order to clarify the effects of irregular and multi-directional nature of load application on soil deposits during earthquakes, multiple series of laboratory tests were conducted on...
Cyclic and Monotonic Undrained Response of Saturated Sands
A unified picture of the undrained monotonic and cyclic loading response of saturated sands is presented. A wide range of initial states of sand are covered in order to consider a full...
Lab Measurements of Gmax Using Bender Elements
This paper describes in detail the installation and use of piezoceramic bender elements in a variety of standard geotechnical laboratory testing equipment at NGI (e. g. , triaxial, direct...
Romanesque Reused
When Union Station in St. Louis, Mo. was built in the 1890s it was the world's largest railroad station. Having been abandoned by the railroads in the 1970s, it was reopened...
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...
Specifications for the Design and Construction of Composite Slabs and Commentary on Specifications for the Design and Construction of Composite Slabs
Composite slab construction is defined as a system comprising normal weight or lightweight structural concrete placed permanently over cold-formed steel decking in which the steel deck...
Performance of Cogoti Dam Under Seismic Loading
At the time of its completion in 1938, the 280 ft (85 m) high Cogoti concrete face rockfill dam was exceeded in height by only one other dam of its type in the world, Salt Springs Dam....
New Exchequer Dam, California
New Exchequer Dam design, in 1963, was in the transition period in which dumped rockfill was being recognized as having undesirable settlement characteristics, and compaction of rockfill...
