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...
Hydropower's Newest Generation
Higher energy prices and strong incentives from the federal government have caused hydropower developers to consider sites that just a few years ago were scoffed at as mere trickles. Intense...
Constitutive Theories for Solids with Defective Microstructure
The nonlinear mechanical response of solids is a macroscopic manifestation of the irreversible changes in its microstructure. The most common modes of the irreversible microstructural...
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...
