Effect of Voids on Creep Rate and Strength
The classic macroscopic Kachanov-Rabotnov model of material damage due to voids is reviewed. Detailed analyses of bulk mechanical properties of dilutely voided materials with certain,...
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...
General Continuum Models for Discrete Structures
New knowledge is presented about the structural behavior of a variety of large repetitive lattice configurations of the type appropriate for utilization in cosmic space. Focus is placed...
On Cyclic Testing with Thin Long Hollow Cylinders
The hollow cylinder device has emerged in recent years as an important tool in the investigation of the dynamic behavior of soils. This paper reviews the stress conditions present in the...
Cyclic and Monotonic Undrained Response of Saturated Sands
A unified picture of the undrained monotonic and cyclic loading response of saturated sands is presented. A wide range of initial states of sand are covered in order to consider a full...
Small Strain Measurements Using Triaxial Apparatus
This paper presents a detailed testing methodology which can be used to determine the cyclic properties of soils at very small strains using triaxial apparatus. A discussion of specific...
Evaluating Nonlinear Soil Behavior Using the Resonant Column
An analysis is presented that attempts to match a mathematical model to the nonlinear behavior obtained from the resonant column test. This model consists of an oscillator with a restoring...
Uplift Behavior of Shallow Soil Anchors?An Overview
An overview is presented of the static uplift (tensile) behavior of shallow anchors used for foundations in soil. Basic anchor types are described, and their general installation and behavioral...
Hurricane Alicia
One Year Later
In the pre-dawn hours of August 28, 2983, Hurricane Alicia ripped its way ashore at the western tip of Galveston Island and moved northward to the Greater Houston area. This storm caused...
Mangrove Creek Dam: Use of Soft Rock for Rockfill
Mangrove Creek Dam is an 80 m high concrete faced rockfill dam (CFRD) completed in 1981. The embankment was constructed largely out of low strength sandstones and siltstones available...
Design of Concrete-Faced Rockfill Dams
Design principles adopted in 1966 by the Hydro-Electric Commission have been applied to nine concrete-faced rockfill dams and remain substantially unchanged. Experience shows that the...
It? Dam?Selection of Type
This paper describes the studies carried out for the type of dam selection for the Ita Hydroelectric Project. Drastic rainfall conditions, large river diversion flows and an abundance...
Need a Dependable Backfill?Try a Flowable Fly Ash
Flowable fly ash is a relatively new cementitious structural backfill material. It can be used in water or in the dry and will flow into place without the usual labor-intensive activities...
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...
Obtaining Reliable Data from Fragility Tests
The parameters discussed in this paper are the same as those present in normal seismic qualification testing. These parameters behave differently in high level acceleration tests and their...
Design of Cirata Concrete Face Rockfill Dam
The Cirata Hydro-Electric Project on the Citarum River in Western Java, Indonesia is at present under construction for Perusahaan Umum Listrik Negara (PLN). The project which is being...
Time Rated Infiltrated Depth Families
A new set of infiltration families has been developed, for 'normal' soils to describe cumulative infiltrated depth versus time. This new family of curves is described...
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...
Shallow Seismic Exploration in Soil Dynamics
Methods of shallow seismic exploration of soils are continually developing and evolving. Advances in techniques and equipment for performing crosshole and downhole tests, new data on interpretation...
Damage Mechanics and Continuum Modeling
Historically, the structural and mechanical engineers are conditioned to model a material in a purely phenomenological sense with little or no regard to underlying physical phenomenon...
