The New 1988 SEAOC Blue Book and 1988 UBC Overview of Lateral Force Section
This paper presents an overview of the lateral force section of the new seismic design provisions of the 1988 edition of the Uniform Building Code (ICBO, 1988), and the 1988 Blue Book...
Equating Dynamic Analysis to Static Code Provisions
Building codes generally prescribe seismic design provisions that include a static lateral force procedure that can easily be combined with the gravity loads to design the structural elements....
Response of Concrete Buildings to Lateral Forces
ACI-ASCE Committee 442 (Response of Concrete Buildings to Lateral Forces) has just issued its report (ACI-ASCE 442 1988a). In that Report, the performance of reinforced concrete buildings...
Guide for Evaluating Engineering Software
This is a practical guide to the problem of assessing the suitability of computer software being considered for use in engineering analysis, design or decision making. Each chapter treats...
Use of POE/POU Technology at US Army Installations
A wide spectrum of adverse water quality characteristics has been experienced at US Army installations throughout the country. These characteristics, both interim and long-term in nature,...
An Investigation of a Pumped Storage Hydropower System
In order to provide a realistic basis of determining the viability of a wind-powered hydroelectric system at a potential site, an evaluation technique has been developed. Basically, this...
Hydropower and Fish Passage Impacts
The Pacific Northwest Electric Power Planning and Conservation Act (Act) of 1980 formed the Northwest Power Planning Council, which establishes criteria and sets goals for developing future...
Analysis of Concrete Gravity Dams Using Microcomputers
Monenco Consultants Limited has developed a microcomputer program entitled 'DS2' for the stability analysis of concrete gravity dams. This paper discusses this...
Simulation for Construction Planning and Control
A prototype system was created as part of a research project for the U.S. Navy Construction Battalions (the Seabees) and has been given the acronym SEACONS (SEAbee Construction Simulation)....
Controlled Yielding of the Lateral Boundaries of Soil Retaining Structures
Lateral expansion of conventional or reinforced soil backfills is necessary to establish and maintain the minimum lateral stresses on soil retaining structures. Laboratory studies are...
On the Post-Flutter State of Cable-Stayed Bridges
This paper deals with the post-flutter vibrations of cable-stayed bridges. An approximate theory and an approximate analytical solution method have been established. A numerical example,...
Research Needs for Rational LRFD Criteria
There are at least a dozen factors causing or influencing impact. Current design specifications consider only a few of these. Location of truck wheel loads within the traffic lanes on...
Effect of Spatial Variation of Ground Motions on Bridges
The effect of spatial variation of ground motions on the response of a two-span bridge is presented. Perfectly and partially correlated earthquake ground motions are used as input motions...
Stochastic Properties of Wind Spectra
In the first part of this paper the correlation function of measured wind spectra is compared with theoretical correlation models assuming a stationary wind process. This comparison indicates...
Probabilistic Structural Response of a Turbopump Blade to Random Pulse Loading
The objective of this work is to develop probabilistic models of the response of a Space Shuttle Main Engine (SSME) turbopump blade to random impact loading. These loads are caused by...
Effect of Air Gap on Platform Reliability
A simplified reliability study of the effect of lateral wave forces impacting the deck of a fixed platform is presented. The reliability of the deck legs, considered the primary resistance...
A Study of Damage in Curved Composite Panels
Composite laminates subjected to a low speed impact, such as a dropped tool or a manufacturing load, often develop an internal delamination. This research studied the effects of a circular...
Surgery in the Microgravity Environment
As man becomes more active in space, the possibility of major medical emergencies requiring surgical procedures will increase. Surgery in the microgravity environment involves many challenges...
Solutions to Space Station Designs
Any space station that is to be designed for extended human use may require gravity. The artificial gravity field required can be produced by rotating the structure. As the Soviets have...
Roadside Safety Design for the Micro-Mini Vehicles
This paper summarizes the results of a study to evaluate the impact performance of widely used roadside safety elements for a 1,500 lb vehicle and to identify potential modifications that...
