History and Development of Fabric Structures
Except for the cave, the tent has been the dwelling for most nomadic peoples from the Ice Age to the present. Until recently, the three basic forms used are namely, the conical, the widespread...
The Body Language of Tensile Structures
Considered to be a 'body' and its visual appearance as 'non verbal, intuitable information,' a building has a Body Language that is employed as a primary mode. Presented is an intuitive...
Tensegrity Structures: Filling the Gap Between Art and Science
Underlining the role of structuralism in contemporary architecture this paper addresses the application of structural morphology in the context of an educational experience. Focussing...
A Quasicrystal for Denmark's Coast
The first true quasicrystal structure will have been built in the fall of 1993 at COAST (The Center for Art, Science, and Technology at the Danish Technical University). With 600 aluminum...
RC Beam-Column Element for Nonlinear Frame Analysis
Recent studies have shown that beam-column finite elements that enforce equilibrium rather than compatibility along the element are better suited for the description of the strength and...
Graphic Visualization for Planning Heavy Lifts
The application of graphical visualization to construction can serve a wide variety of objectives and offers many significant benefits. Heavy lifts are an important component of industrial...
Practical Solution of the Flexibility to Stiffness Transformation Problem With a Mathematical Assistant for the Personal Computer
This paper will show how a relatively complicated structural mechanics problem can be solved easily with a symbolic manipulation program. Specifically, the authors will demonstrate how...
Settlement of Embankments on Soft Clays
It is now possible to make reliable predictions of settlement of embankments on soft clays. In most situations, where the embankment is designed to resist undrained instability during...
Compressibility of Clays: Fundamental and Practical Aspects
The compressibility of natural clays is influenced by strain rate, temperature, sampling disturbance, stress path and some restructuration factors. The first part of the paper reviews...
Methods to Reduce the Settlement of Embankments on Soft Clay: A Review
New trends have been observed during the past ten years in the practice of settlement control for embankments on soft clays: they include increased use of rigid (piles) or semi-rigid (stone...
Settlement Behavior of an Avalanche Protection Gallery Founded on Loose Sandy Silt
An avalanche protection gallery located in the Swiss Alps was founded on alluvial ground close to the steep rocky mountainside. The rear retaining wall, at a variable distance of a few...
Testing and Predicting the Movement of a Drilled Shaft in New Mexico
The New Mexico State Highway and Transportation Department (NMSH&TD) have been using drilled shafts for supporting bridges in the State of New Mexico. Several drilled shafts were...
Preloading Organic Soils to Limit Future Settlements
This paper presents the authors' experience in preloading organic soils in south Florida to allow the construction of roadways, utilities, and low-rise residential structures on shallow...
Geocell Mattress Effects on Embankment Settlements
Laboratory investigations and finite element analyses of geocell mattresses beneath embankments were performed to determine the effect of such mattresses in reducing settlements. Eight-foot...
Cyclic Loading for the Measuring of Soil Consolidation Parameters
A method of determination of soil consolidation characteristics using sinusoidal loading is described. It can be performed in laboratory test or in situ observation as well, with different...
Settlement of Large Mat on Deep Compressible Soil
This case history describes the settlement analyses for a large load compensated (floating) mat foundation on a deep deposit of normally consolidated clay of variable thickness. Large...
Performance of Three Large-Diameter Oil Tanks on Soft Clay
Preloading using a clay surcharge at the proposed locations of 3 large-diameter steel oil storage tanks founded on a 20-m thick stratum of soft Nile-delta silty clay produced about 1.5...
Settlement Measurements of 50-ft High Embankments at the Chesapeake & Delaware Canal Bridge
This is a case history of instrumented settlement measurements on 49 to 56' (15-17 m) high bridge approach embankments of Delaware State Route 1 crossing of the Chesapeake & Delaware...
Compressibility for Sand Under One-Dimensional Loading Condition
Empirical equations for one dimensional compression of sand do not include parameters characterizing properties of sand grains (e.g. moduli, size and shape of sand grains, and friction...
Settlement of Peats and Organic Soils
New advances in investigation of settlement of peats and organic soils and issues related to construction over such soft ground are presented. Peats and organic soils are well known for...
