DFW Concrete Block Pavement Taxiway Construction
The first concrete block pavement constructed on an airport in the United States was constructed at Dallas/Fort Worth International Airport during 1990. The use of concrete blocks on three...
A Concrete Alternative to Runway Reconstruction
Faced with the prospects of losing commercial air service for up to two months, the Charleston County Aviation Authority, the Charleston Air Force Base and their engineers had to look...
Performance of Airport PCC Pavements During Spring Thaw Periods
The portland cement concrete (PCC) pavements at two Wisconsin airports, Central Wisconsin Airport in Mosinee, and Outagamie County Airport in Appleton, were monitored during spring thaw...
An Airfield Pavement Consultant System (AIRPACS) for Rehabilitation of Concrete Pavements
Airfield pavement knowledge captured by this research showed that knowledge-based techniques can be used to quickly select and design rehabilitation alternatives for a runway, taxiway...
Historic Dam Rehab: Handle with Care
A growing number of dams across the U.S. are aging and in need of rehabilitation, but can they be brought up to current codes without compromising their historic integrity? Improved methods...
Retrofitting Fossil Plant Facilities Structural Perspectives
This publication, Retrofitting Fossil Plant Facilities: Structural Perspectives, was prepared by the Retrofit Task Committee of the Fossil Power Committee of the American Society of Civil...
Pile Test for Earthquake Repair
Load testing for existing concrete piles was specified as part of a seismic retrofit at the Port of Oakland after the Loma Prieta event. The Port wished to use heavier cranes at cargo...
Anchors in the Desert
The Southwest desert isn't usually thought of as a hotbed of seismic activity, but earthquakes have occurred there. And if Arizona's Stewart Mountain Dam, a double-curvature...

Time Dependent Stochastic Characteristics of the Lateral Random Vibration of Tall Structures with Circular Cross-Section
From full scale measurement of the pressure field at three levels of a concrete chimney with 230 m height the lift coefficient is deduced and the lateral oscillation is investigated. The...
Stochastic Behavior of Concrete Arch Dam-Reservoir Fluid-Foundation Systems in Nonstationary Random Vibration
The behavior of elastic arch dam reservoir fluid system subjected to ground acceleration excitations has been studied extensively by Chopra and his colleagues. In their studies, the excitations...
Safety Assessment of an Existing Concrete Gravity Dam
The safety and/or probability of failure of an existing 146 m high concrete gravity dam subjected to normal static and dynamic loads is evaluated. Three modes of failure were considered,...
Global Damage Indices and Nonlinear Structural Response
Damage indices based on equivalent linear parameters have been proposed for the analysis of global seismic damage. The analysis of shaking table experiments and strong motion records has...
Automated Damage-Controlled Design of RC Buildings
This paper presents an automated damage-controlled design method, which aims for uniform damage distribution throughout the entire building frame while respecting the strong-column weak-beam...
Simulation of Seismic Damage of RC Structures in Eastern US
A normalized index for evaluation of structural damage was developed based on the relation of demand and capacity. The proposed formulation combines two sources of damage: permanent deformation...
Aseismic Reliability of a Strengthened R.C. Single Story Industrial Building
Based on results of seismic hazard analysis for a considered site, seismic reliability of a strengthened RC single-story industrial building against collapse has been evaluated. Inelastic...
Durability Analysis of Reinforced Concrete Structures
This paper attempts to provide a fundamental basis for estimating the remaining life of reinforced concrete structure. In the damage assessment of reinforced concrete structure, some quantity...
Damage Evolution in Reinforced Concrete Members Under Cyclic Loading
The paper presents a new damage indicator D, valid for reinforced concrete sections under cyclic loading. DQ, based on sectionally absorbed energies,...
On the Failure Probabilities of R/C Chimneys
A procedure to estimate failure probabilities of structural systems such as reinforced concrete (R/C) chimneys under severe wind loading which allows for considering realistic correlation...
Nonlinear Dynamic Response of Industrial R/C Chimneys
Gust response factors (GRF) based on nonlinear dynamic analysis including the P? effect are calculated. All sample structures analyzed show clearly that, for wind speeds exceeding the...
