Loading, Geometry, and Analysis
This Standard applies to latticed steel transmission structures. These structures shall be either self-supporting or guyed. They consist of hot-rolled or cold-formed prismatic members...
Changing Channels
When the strict design parameters of a correctional facility in remote Pennsylvania meant blocking a headwater stream, a team of environmental engineers rerouted the waterway 400 ft (122...
Framing a Work of Art
One of the most visually unique building designs of the twentieth century, the Guggenheim Museum project in Bilbao, Spain, required an innovative structural engineering solution and pioneering...
Pier Width and Local-Scour Depth
Presented here are the results of an enquiry into the effects of pier width on local scour depth. The results show that scour depth does not scale linearly with pier width unless there...
Quail Creek: A Case Study of Restoration Using Native Materials
Quail Creek, a stream in northern Baltimore County, Maryland, was restored in 1990 using the approach developed by Rosgen to diagnose the problems, and determine the parameters for stable...
Bridge to the Past
Constructed by Maya builders during the seventh century, the PreColumbian bridge at Yaxchilan was the longest in the world for over seven hundred years. Little remains today of this unique...
Functional Highway Design
In the past, the common highway design development process used by government agencies has often failed to incorporate the lessons learned from operational experience and research. However,...
Conceptual Design and Characteristics of A Dual-Arm Cam-Lock Manipulator
Recent developments in the area of smart structures indicate that variable geometry/stiffness truss network is of fundamental importance in designing smart transformable structures and...
Prisms and Antiprisms
Prisms form a group of mathematical figures, that have found widespread application in many disciplines, but especially in architecture and in building structures. They have two identical...
Ultimate Loading Capacity of Braced Domes
The stability behaviors of a practical latticed dome with 40 metres span are studied in this paper. The geometric and material nonlinear behaviors, as well as the effects of the initial...
The Nature of Structural Morphology and Some Interdisciplinary Examples
Among members of IASS, the most common definition of Structural Morphology is the study of interaction between geometrical form and structural behavior. The most significant structural...
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...
Space Frames and Polyhedra
Polyhedra are easy to build and they can be useful as architectural matrices. Relatively small polyhedra can be built as faceted structures; very large ones can be built with space frames....
Hyper-Geodesic Structures: Excerpts from a Visual Catalog
A class of hyper-geodesic surface structures is presented. The surfaces of known polygons, polyhedra, plane and space tessellations, higher dimensional polytopes can be subdivided into...
Morphology of Reciprocal Frame Three-Dimensional Grillage Structures
This paper is an introduction to the morphology of structures using the Reciprocal Frame (also known as Mandala Dach in Germany) which is a patented three-dimensional beam grillage structural...
Applicability of Pseudo-force method to Highly Nonlinear Dynamic Problems
This paper deals with solution of nonlinear dynamic problems using Pseudo-force method. A solution algorithm involving Pseudo-force method is presented. The objective is to investigate...
Numerical Simulations of the CCS under the Joint Effects of Coastal Geometry and Surface Forcing
Using the S-Coordinate Rutgers University Model (SCRUM) of Song and Haidvogel(1993), a coupled coastal (86 m depth) and deep ocean (4600 m depth) California Coastal region has been investigated...
3-D Coordinates - A Universal Rectangular Coordinate System for a GIS and Other Spatial Databases
Rules of solid geometry and 3-dimensional (3-D) rectangular coordinate systems are well known and used in many applications. Points on or near the earth's surface have long been described...
A Symbol-form Mapping Framework for Conceptual Design Support
Engineering design involves a strong notion of the geometric structure of design artifacts. Research efforts to support the geometric aspects of design have concentrated on the representation...
Model-Prototype Conformance of a Submerged Vortex in the Intake of a Vertical Turbine Pump
Submerged vortices are commonly found in sump intakes of vertical turbine pumps. These vortices are known to cause increased vibration and at times degrade pump performance. Approach flow...
