Load Combinations for Codified Design
Loading requirements used in current standards for structural design are not consistent in their conceptual basis, appearance or use. Unified limit states design procedures for structures...

A Reassessment of Codified Limit States Design
This paper examines the nature of design codes and their relation to engineering practice. It suggests that codes impose unjustifiable and, in the long term, destructive constraints on...

Stochastic System Identification in Structural Dynamics
Recently, new identification methods have been developed by using the concept of optimal-recursive filtering and stochastic approximation. These methods, known as stochastic identification,...

Time Series Analysis of Wind Pressures on Low Buildings
A new methodology for the description of local wind pressures on the building envelope of mono-sloped roof buildings by using time series analysis is described. A simple AR(1) model has...

EXPSYS: Offshore Structures' Expert System
This paper builds a framework of an expert system in the area of offshore structures. Expert systems, in general, are classification systems. They embody a core of knowledge about a specific...

Dynamic Response of Tall Buildings to Wind Loads
The purpose of this study is to perform a probabilistic analysis of tall buildings subjected to wind excitation. A time domain simulation is first applied to the nonlinear problem. After...

An Intelligent Design Support System for Computer-Aided Site Development
This research proposes an intelligent design support system (DSS) integrated with a CAD environment for building site planning and development. The DSS is used for providing a good initial...

CADD Applications in Water Resources Design
CADD can provide substantial benefits, in terms of speed and ease of revisions, in the design of civil engineering projects, including water resources facilities. However, current design...

Building Code Requirements for Masonry Structures and Specifications for Masonry Structures
The proposed Building Code Requirements and Specifications for Masonry Structures presented in this book were developed by the Joint American Concrete Institute, American Society of Civil...

The `Down' of Top Down
The 800-space parking area for the Milwaukee Center was built in a four story deep basement of the building. In order to excavate the area without damaging two adjacent historic structures,...

U.S. Embassy In Moscow: A Structural Stalemate
The fate of the nearly finished American embassy in Moscow should be decided by next fall. In the meantime, it stands empty. On April 15, 1987, Congress made public a National Bureau of...

Current Developments in Reinsulating/Waterproofing Underground Steam Mains in New York City
The objective of Con Edison's reinsulation project is to develop the materials and technology necessary to reinsulate those steam distribution mains having excessive thermal...

Microcomputer Knowledge-Based Expert Systems in Civil Engineering
This book contains sixteen papers presenting applications of expert system technology to civil engineering problems with emphasis on microcomputer implementations. It is divided into four...

A Summary Description of Design Criteria, Codes, Standards, and Regulatory Provisions Typically Used for the Civil and Structural Design of Nuclear Fuel Cycle Facilities
A summary of design criteria, codes, standards, and regulatory provisions applicable to the civil and structural design of the eight principal facilities of the nuclear fuel cycle are...

Quality in the Constructed Project
A Guideline for Owners, Designers, and Constructors
This book provides guidelines and recommendations for owners, design professionals, and constructors on how to provide quality in constructed projects. Roles, responsibilities, and limits...

Design and Evaluation of Storm Water Detention Facilities Using a Design Storm and Probable Maximum Storm
When designing a storm water detention facility, both a design storm (DS) and a probable maximum storm (PMS) should be considered. The DS is used to design the facility. The PMS is used...

Kissimmee River: Engineering Approaches for Restoration
The Kissimmee River, located in central Florida, was channelized for flood control during the 1960s. Movements by environmental interest groups have produced strong sentiment to restore...

Terrestrial Trends for Building Technology in North America
This paper discusses new building technologies that will develop in the early 1990's to become significant technologies by the mid 1990's. The perspective is...

Candor Chasma Camp
This paper proposes a camp at Mars, in the Coprates region of the Valles Marineris rift, just below the equator on Candor Mensa 6�-12'S, 73�-30'W. Beginning at...

Homesteading Mars
The author gives serious study to setting up a permanent Martian base during the first or second manned Mars mission. The savings of fuel and equipment for the return trips might pay for...
