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...

Nonlinear Macroscopic Finite Element Model for Masonry Walls
A macroscopic finite element model which includes both transverse shear effects and nonlinearity due to cracking has been developed for masonry. These features are accommodated using a...

Shear Design of Masonry Walls
The paper presents a summary of a research project carried out at the Swiss Federal Institute of Technology Zurich to develop a design method based on the ultimate strength of masonry...

Shear Stresses in Composite Masonry Walls
The behavior of composite masonry walls subjected to inplane loads is a subject that has received little attention during the last few years. The small amount of experimental and analytical...

Torsional Simple Shear Apparatus for Drained and Undrained Cyclic Testing
Since a cyclic triaxial compression apparatus was first used to study liquefaction of saturated sandy soil, many different types of cyclic shear devices have been used to investigate drained...

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...

Shear Moduli Measurements under True Triaxial Stresses
The effect of state of stress on the shear wave velocity and shear modulus of a dry sand was examined. Testing was performed in a large-scale triaxial device in which cubic soil samples...

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...

Cyclic Simple Shear, Torsional Shear and Triaxial�A Comparative Study
Many different testing apparatus are used to duplicate in laboratory soil samples the stress state generated in situ by earthquakes. A wide diversity of data has been generated and this...

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...

Kotmale Dam and Observations on CFRD
A concrete faced rockfill dam was the type selected for the 300 ft (90 m) dam at Kotmale in Sri Lanka for reasons of economy and speed in construction. Standard design concepts were tailored...

Foundation Design Considerations for Detroit DPM
The design loadings for support of the elevated guideway of the Detroit Downtown People Mover (DPM) consist of high vertical as well as horizontal loads. In order to simplify foundation...

Earthquake Experience Data on Power and Industrial Structures: Applications to Seismic Design and Evaluation
An extensive study was conducted to document the seismic performance of typical power plant and industrial structures in selected recent strong earthquakes and to correlate the performance...

Aseismic Capability Prediction from Failure Data
Forensic engineering evaluations of failures have produced a wealth of technical data. In this paper, evaluation of representative failure data from one practitioner provided relevant...

Seismic Design-Qualification of Non-Safety Related Items in Safety Related Envelope
This presentation pertains to Seismic Design-Qualification for those portions of structures, systems, or components in a Nuclear Plant whose continued function is not required but whose...

Recent Developments in Resonant Column Testing
The resonant column method of testing soils is reviewed. Recent developments in equipment, specimen configurations, and testing schemes are presented. Some equipment can perform both resonance...

Probabilistic Basis for Design Criteria in Reinforced Concrete
This collection of papers presents the results of research on the variability of reinforced concrete members carried out at the University of Alberta, Edmonton, Canada, during the period...

Advances in the Art of Testing Soils Under Cyclic Conditions
The session on Advances in the Art of Testing Soils under Cyclic Loading Conditions was organized by the Soil Dynamics committee of the American Society of Civil Engineers in an endeavor...

Roller Compacted Concrete Pavements in British Columbia, Canada
Roller Compacted Concrete (RCC) pavement is an outgrowth of the traditional cement-treated aggregate base (soil-cement) method of street and highway construction. The major use in British...
