Failure of a Large Reinforced Concrete Pipeline
This paper describes the damage that occurred when a landslide overloaded an 11 ft diameter reinforced concrete pipeline. The 8 ft lengths of pipe, each of 11. 5-in. wall thickness, were...
Earth Pressure and Surface Load Effects on Buried Pipelines
Rational techniques for analyzing earth pressure and surface load effects, based on finite element analysis methods, have been developed and applied extensively to the design of buried...
Characterization of Soil Arching Above Buried Conduits
Conventional ways of assessing the effects of soil arching over buried conduits were examined by means of finite element analyses. It was found that neither of the conventional soil arching...
KEMCOR?A Chemical and Corrosion Resistant Piping System
KEMCOR is a new underground composite pipe system designed for chemical process use in such industries which require a high degree of corrosion resistance to varying concentrations and...
Prediction of Fine Sedimentation in Small Marinas
Shoaling due to fine, cohesive sediment deposition in small marina-type basins is governed by basin geometry, hydrodynamic factors and sediment load in outside waters. An easily programmable...
Economics of Hydrothermal Power Development
The overall performance of a hydrothermal power plant with pumped storage is more cost effective than its competitive counterparts such as oil and gas turbine-generators. The operation...
How Will People Movers Affect Downtown Areas?
The year 1980 was a pivotal one for the downtown automated people mover development process in both Detroit and Miami. In that year both cities completed their preliminary engineering/environmental...
The Neglected Challenge in Metropolitan Area Transportation
The central fact about metropolitan area transportation is the gross mismatch between the medium and low density patterns of settlement that are dominating the evolution of metropolitan...
Investigation of Design Criteria for APM Guideways
Designers have relied mostly on the provisions of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway Bridges. Sometimes...
Human Interface Design of an APM Control Center
The control center of an Automated People Mover (APM) system is a man-machine system. Both software and hardware aspects of the design of the monitor room that directly affect ease of...
A New Alternative in Steel Construction?Partially Restrained Connections
Lack of formal training in methods as well as the lack of specific guidelines have limited the understanding and utilization of semi-rigid connection technology. A renewed interest in...
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...
Behavior of Cavity Masonry Walls Under Out-of-Plane Lateral Loading: An Analytical Approach
In this paper, a finite element model is used to analyze cavity walls in an attempt to understand their complex behavior and to evaluate the adequacy of the assumptions embodied in the...
Wall/Floor-Slab Interaction in Brickwork Structures
The paper summarises the results of three series of tests on sections of brickwork structure carried out with a view to determining the characteristics of wall/floor slab joints in terms...
Decision Support System for Tunneling
This paper first discusses methodologies for considering geological uncertainty in tunneling projects and for determining the most economic excavation and support methods under such condition;...
Revitalization of Existing Buildings: An Owner's Perspective
Revitalization of the large stock of existing buildings in this country is of paramount importance today to building owners, who want the value of existing properties to appreciate as...
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...
The Uplift Capacity of Helix Anchors in Sand
Results of field and laboratory investigations of the uplift capacity of helix anchors in sand are presented. Equipment and instrumentation were used to measure uplift load, anchor deflection...
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...
Forecasting the Demand for Electricity: An Examination of Alternative Approaches
This paper examines several approaches to forecasting national-level electricity demand. The various approaches are briefly examined, and the strengths and weaknesses of each are discussed....
