Highway Damage Due to Subsidence
In this study subsidence profiles over three longwall panels, which were mined beneath state highways in Southeastern Ohio, were obtained. Immediate and short term subsidences were recorded....
Subsidence Abatement Projects in Wyoming?An Overview
Abatement projects were undertaken to prevent or minimize further subsidence in Wyoming communities. The paper gives a brief historical background on the mining activity in Wyoming. Subsidence...
Coal Mine Subsidence and Structures
Underground coal mining has occurred beneath 32 multiplied by 10**9m**2 (8 million acres) of land in the United States and will eventually extend beneath 162 multiplied by 10**9m**2 (40...
Advanced Reconstruction for Subsidence-Damaged Homes
To address many of the residential damage-reconstruction problems from mine subsidence a research and development project was undertaken in Illinois. Phase I of this project is complete...
Mining Subsidence Effects on Transportation Facilities
This paper presents case history information about mining subsidence effects on transportation facilities, including bridges, pavements, and culverts. Most of the field observations pertain...
Truck Operating Characteristics in Relation to Safety
For a two-year period large truck crashes on the interstate system in Washington State were investigated using a case-control method. For each large truck involved in a crash, three trucks...
Impact of International Competition on Construction Technology?A Perspective
The strong showing by non-U. S. contractors in the development of new construction technologies has had a significant impact on the redistribution of construction dollars in world markets....
Evaluation of Air Quality Methods in the Asbestos Work Area
Air monitoring is a technique that is routinely used to measure the level of asbestos in a given airspace. This technique has changed significantly since its first use in the asbestos...
On the Post-Flutter State of Cable-Stayed Bridges
This paper deals with the post-flutter vibrations of cable-stayed bridges. An approximate theory and an approximate analytical solution method have been established. A numerical example,...
Burlington Cable-Stayed Bridge
The Burlington cable-stayed bridge will carry US34 over the Mississippi River from Burlington, Iowa to Gulfport, Illinois. There will be two 12-ft lanes in each direction plus an acceleration...
Quincy Bayview Bridge?Construction Control
A cable-stayed bridge crossing the Mississippi River at Quincy, Illinois, was completed in August 1987. The structure includes twin concrete towers and a hybrid deck section. The cable...
Load-Sharing and Reliability of Wood Systems
A methodology for the study of reliability of light-frame wood structural systems is presented. Reliability levels associated with the bending strength limit state of such systems are...
A Reassessment of Codified Limit States Design
This paper examines the nature of design codes and their relation to engineering practice. It suggests that codes impose unjustifiable and, in the long term, destructive constraints on...
Application of Bayesian Methods to a Geotechnical Site Investigation in Mississippi
In 1981, the Army Corps of Engineers constructed an ammunition storage area at Bay St. Louis, Mississippi. This storage area is part of the Mississippi Army Ammunition Plant (MSAAP). Prior...
Damage Accumulation Models for Bridges
In the study summarized in this paper the serviceability and ultimate limit states were reviewed for concrete and steel girder bridges. A model is proposed to evaluate strength and remaining...
Effect of Spatial Variation of Ground Motions on Bridges
The effect of spatial variation of ground motions on the response of a two-span bridge is presented. Perfectly and partially correlated earthquake ground motions are used as input motions...
Reliability Analysis of Single-Headed Anchor Bolts
Several design equations for predicting the capacity of single-headed anchor bolts embedded in plain concrete have been recommended in the United States. The capacities predicted by these...
Stochastic Properties of Wind Spectra
In the first part of this paper the correlation function of measured wind spectra is compared with theoretical correlation models assuming a stationary wind process. This comparison indicates...
Stochastic Risk Assessment for Structural Safety
Through the United States the structural safety of major and/or innovative structures has become a serious concern for engineers and to the general public. The objective of this paper...
Bayesian Updating of Seismic Fragilities of Nuclear Power Plant Components
Seismic fragility is represented by a curve of the conditiional probability of failure as a function of the peak ground acceleration. Since there are many uncertainties in the model and...
