The Ultimate Load Design Method of R/C and P/C Shell
Based on the testing results of 20 full size shells and models, the ultimate load analysis method is proposed to design four different kinds of reinforced concrete shallow shell structures....
Substitute Wind Concept for Elastic Stability of Cooling Tower Shells
The influence of the nonaxisymmetric wind distribution on the stability behavior of cooling tower shells is examined. It is demonstrated, considering about 50 cooling tower shells, that...
Applied P-Delta Methods in the Design Office
At first glance some axioms of a P-Delta analysis appear to be paradoxical. First, the P-Delta effects are a direct function of the depth of the structure parallel to the wind direction....
Practical Application of PR Connections and Second Order Analysis
In the present LRFD Specifications type PR (Partially Restrained) connections are described as those where the connections of beams and girders possess an insufficient rigidity to hold...
Design of Steel Buildings for Second Order Effects
Several methods of calculating corrected effective length factors for unbraced frames are presented and discussed. In addition, an alternate format is suggested for the ASD beam-column...
Second Order Analysis of a 47-Story Building
A modern day second order analysis and ultimate strength review is made of a hypothetical 47-story unbraced frame designed under the 1969 AISC Specification. The original design is part...
Tall Building Stability -- Practical Considerations
Simple techniques for including lateral stability effects in the design of tall buildings are proposed. The application of these techniques in the design of a 66-story building is described....
Frame Stability - A Canadian Designer's Approach
The deficiencies and fallacies of the simplistic effective column length approach to frame stability are demonstrated through its application to a 57-story rigidly framed building structure....
Application of a Hybrid Strategy for Structural System Reliability Analysis
The authors have attempted to explain a strategy for structural systems reliability calculations. In essence, it involves the use of different methods at appropriate times in the search...
New Directions in the Application of Probabilistic Concepts in the Seismic Analysis of Nuclear Power Plants
During the last 8 years, probabilistic concepts have been used in the seismic analysis of nuclear power plants. Probabilistic risk assessment (PRA) has been the primary vehicle for performing...
Reinforced Concrete Column Reliability
A method is proposed whereby the reliability is obtained using the stable configuration approach of structural system reliability. The configurations are defined based on imposed strains...
Reliability of Structural Systems With Multiple Limit States
The purpose of this paper is to present a systematic treatment of the reliability of structural systems with multiple limit states. Several performance criteria (e. g. , excessive deflection,...
Mechanical Properties of Model Ice Rubble
Experiments were conducted to measure the mechanical properties of bulk ice rubble. Tests were performed under isothermal and plane strain conditions. Fresh water ice blocks were used...
Case Studies of Displacement-Induced Fatigue
The potential for displacement-induced cracking is a result of the co-existence of two conditions: an abrupt change in stiffness and a periodic force opposing it. Case studies of retrofitted...
Projectile Penetration Into Reinforced Concrete and Steel Targets
This paper presents brief preliminary results of a research program sponsored by the Air Force Weapons Laboratory (AFWL) to investigate the interaction of 30-mm cannon projectiles with...
Top Projects of 1987
Five notable entries in the 1987 Outstanding Civil Engineering Achievement competition are summarized. The Keehi Interchange of the H-1 Freeway in Honolulu is only 1.9 miles long, but...
Geotechnical Practice for Waste Disposal '87
This volume contains 55 papers covering many aspects of geotechnical issues associated with waste disposal. The papers represent advances during the intervening decade since the first...
Environmental Engineering
The American Society of Civil Engineers annually sponsors a Specialty Conference on Environmental Engineering. The 1987 Conference was held in Orlando, Florida on July 7-9, 1987 with cooperation...
Coastal Hydrodynamics
This book includes papers presented at the ASCE Specialty Conference on Coastal Hydrodynamics Conference, at the University of Delaware, June 28-July 1, 1987. The papers review the state...
Dioxin and Resource Recovery
The 1987 ASCE Dioxin and Resource Recovery Symposium was held at the New York Hilton Hotel, New York on February 10, 1987. The conference served as an opportunity to assess the issue of...
