The Slender Tower of 52-54 East End Avenue
The structural system for the 52-54 East End Avenue project is presented. The 40 story residential tower with as aspect ratio of 12: 1 is one of the most slender buildings constructed...
The Structural History of the Jacob Bachmann Tavern
The Jacob Bachmann Tavern is located in Easton, Pennsylvania. It is a collection of four interconnected buildings that have been constructed and modified over a period of 240 years. Structural...
Nonlinear Analysis of a Reinforced Concrete Folded Plate Structure
This paper deals with the ultimate load analysis of a reinforced concrete (RC) folded plate shell subjected to dead load and monotonically increasing live loads, statically applied, using...
Repair of a Cracked Cooling Tower Shell Based on Numerical Simulations
The present condition of a 30 years old cooling tower shell made of reinforced concrete is characterized by a relatively large number of long, thermally induced meridional cracks. For...
Microsurfacing Urban Pavements
A European maintenance technique called microsurfacing can add years to the service life of cracked, ravelled pavements--with minimal interruption to traffic and for less than half the...
Computer Modelling of Comminuting Granular Media
Using generalized continuum mechanics, generalized damage theories for granular materials in comminution processes are proposed. The generalization is accomplished by treating the average...
Rotating Crack Model and Fracture in a R/C Medium
In this study the potential of the development of cracks in the members of a reinforced concrete large panel structure is considered. The analysis is carried out using finite element modeling...
Strain Measurement on the Runner of a Hydroelectric Turbine
Twelve strain gages were installed on the 10-m-diameter runner of Unit G-23 (700 MW) at Grand Coulee Dam, Third Powerhouse. The gages were located on both the pressure and suction sides...
Fracture Mechanics Applied to Geotechnical Engineering

Use of Long, Variable Length Steel Fibres in Shotcrete
Steel wires are cut to fibres in a shotcrete nozzle and directly incorporated in the ejected shotcrete. Long and variable length fibres can be used. The fibre material is better utilized...
Steel Fibre Reinforced Wet Shotcrete with Very High Deformation Capacity
Tests have been carried out under site conditions in Norway where the performance of 40 mm long DRAMIX fibres was compared with normally used 30 mm fibres. The fibres were mixed into the...
Geophysical Methods for Fracture Characterization in and Around Potential Sites for Nuclear Waste Disposal
Historically, geophysical methods have been used extensively to successfully explore the subsurface for petroleum, gas, mineral, and geothermal resources. Their application, however, for...
NDE of Steel Bridges by Acoustic Emission
Acoustic emission technique (AE) was used to investigate fatigue cracking phenomenon during a series of laboratory tests of various bridge steels and during field testing of an in-service...
After-Fracture Response of a Two-Girder Steel Bridge
The I-40 bridges over the Rio Grande are due to be razed in mid 1993 due to geometry and traffic safety considerations. The bridges are classified as 'fracture critical' two girder steel...
Modal Analysis Technique for Bridge Damage Detection
The dynamic responses of a wide-flange steel beam with artificially introduced cracks were studied analytically and experimentally. Frequencies, displacement mode shapes (DMS) and strain...
Analysis of Masonry Walls with Smeared and Discrete Crack Models
To design modern reinforced masonry structures for seismic loads and to evaluate the seismic safety of existing unreinforced masonry buildings, the shear resistance of masonry shear walls...
Strength, Behavior and Repair of Masonry Infills
Results of a series of experiments are presented on seismic performance of unreinforced masonry infill panels. The object of the investigation is to examine the loss of out-of-plane strength...
Signal Analysis for Quantitative AE Testing
Quantitative acoustic emission (AE) techniques can be used to monitor crack growth and to deduce microfracture mechanisms in quasi-brittle materials. Multichannel data acquisition systems...
Full Scale Dynamic Monitoring of Highway Bridges
Sensitivity of identified modal properties by physical testing is critical for automated monitoring of bridge structural condition. It is investigated here considering flexure modes and...
Rehabilitation of Cracked Embankment Dams
Cracking is a common phenomenon in many earth embankment dams and especially those small to medium size dams constructed on compressible soil foundations. Collapsible soil conditions,...
