Strength Data Base for LRFD of Transmission Lines
Reliability-Based Load and Resistance Factor Design (LRFD) has been proposed as a desirable alternative or a complement to the National Electrical Safety Code (NESC) for the structural...
Adfreeze Strength of Ice to Steel Pipe Piles as a Function of Temperature
A study was initiated to determine the adfreeze bond strength between steel pipe piles and freshwater ice as a function of temperature. Tests were conducted at an average strain rate of...
Iceberg Impact Load on a Gravity Based Structure
The mechanics of the eccentric collision of an iceberg against a fixed, rigid, gravity based structure are discussed. A closed form solution is derived for the case of infinite friction...
A Self-Refrigerated Gravel Pad Foundation for Large Thermal Loads
Design criteria for a proposed power plant at Thule Air Force Base, Greenland, involved both large thermal loads from the diesel engines and large static loads from an eight foot thick...
Snow Load Design for Colorado Mountains
During the past decade, Colorado mountain construction has experienced a period of rapid growth. New ski resorts and other business developments have resulted in many new facilities. For...
Reinforced Roads Bridging Voids
A mathematical model was developed to design a pavement section reinforced with a geotextile or related product to span a void. A full scale field test was conducted to verify the model....
Ice Cover Research?Present State and Future Needs
Presentation reviews, at first, a number of problem areas in ice engineering, such as the determination of vertical and horizontal forces floating ice covers exert on fixed structures,...
Wave Forces on an Arctic Monotower Platform
At offshore lease sites located along the western coast of Alaska, longer periods of open water can be expected. As a result, wave induced hydrodynamic loading will become a more significant...
Bearing Capacity Calculations for Piles in Permafrost
Small-scale model piles frozen in various soils were tested at constant rates of displacement and constant load. The derived values were used to calculate the maximum allowable stress...
Dynamics of Machine Foundation
The art of designing machine foundations, supporting vibratory load has changed from the approximate rule-of-thumb to the scientifically sound engineering procedure. However, the vast...
Interactive Analysis and Design Program for Girder Bridges
An interactive microcomputer program for the analysis, design, and rating of girder bridges is presented. The program, GBRIDGE, is user-friendly, menu-driven, and developed in modular...
Dynamic Soil-Structure Interaction by the Boundary Element Method: A Comparison Study
A comparison study of three Boundary Element Method approaches is attempted on the basis of a typical three-dimensional, dynamic soil-structure interaction problem. The vertical transient...
Solving Finite Element Structural Dynamic Problems on Small Computers Using Semi-Explicit Methods
Numerical techniques based on the partial decomposition of a coefficient matrix, are developed for structural dynamic problems. Improved iterative techniques are discussed which could...
Response of Eccentrically Braced Tall Buildings
The inelastic dynamic response aspects of tall steel buildings with eccentric K-bracing and eccentric X-bracing systems are examined, when subjected to factored El-Centro and computer...
Predictions of Thermally Induced Stresses in Thin Walled Grain Storage Bins Under Declining Ambient Temperatures
A generalized constitutive equation for cohesionless sands based on elasto-plastic theories is applied to a grain bin system. The validity of the theory is established through the finite...
Measuring Dynamic Occupant Loads by Microcomputer
Present building codes regard live loads caused by human movement as deterministic; values are based upon experience and tests run in 1912, 1922, and 1932. An experimental project to statistically...
Interactive Computer Graphic Seismic Design of Frames
An interactive computer graphics approach for earthquake resistant design of two and three-dimensional steel frames is presented. Analysis and design are possible from code-related equivalent...
Integrated Design of Concrete Flat Plate Structures
An integrated structural design and drafting system for concrete flat plate floor systems is described. This system provides at a single computer workstation the tools necessary to layout...
How To Design Highway Retaining Walls?A Practical Application of CADD
The recent work developed at the University of Missouri-Rolla (UMR) including optimization algorithms and two computer programs, ODSEWS-2D-II and ODRESB-3D are discussed. Several numerical...
