Reliability-Based Design of Transmission Line Structures
Reliability-Based Design (RBD) is an emerging concept for the design of transmission line structures and holds the potential to reduce the cost of lines or increase their reliability....

Applications of Probability for Structural Analysis in the Nuclear Industry
Probabilistic techniques are being used as part of structural analysis in the nuclear industry to investigate various safety-related issues. Historically nuclear power plants have been...

Overview of Programs at Sandia National Laboratories
This paper presents on overview of the containment integrity programs at Sandia National Laboratories. Companion papers at this conference give greater details about the construction,...

Design and Construction of A 1/6 Scale, LWR Reinforced Concrete Containment
This paper summarizes the closely coordinated engineering and construction planning associated with the design and construction of a reinforced concrete containment model. Designed at...

Energy Approach of Earthquake-Structural Design Analysis
A new procedure developed from the earthquake energy concepts is presented in this paper. A short-squat building and a long-slender building are analyzed using the presented procedure....

Mitigation of Wind-Induced Vibration of Tall Buildings
This paper summarizes a detailed study of the sensitivity of building acceleration to changes in structural stiffness, mass and damping and to the eccentricities in the centers of stiffness...

Aerodynamic Methods for Mitigating Wind-Induced Building Motions
Excessive wind-induced motions of tall buildings most frequently result from vortex shedding induced across-wind oscillations. This form of excitation is most pronounced for relatively...

Local Wind Pressures on Roofs
The paper reviews the results of the most recent research studies in the evaluation of wind pressure coefficients for the design of roof cladding elements. The effect of roof geometry...

Wind Effects on Loose-Laid Cladding Systems
Modern roofing systems for flat roofs frequently make use of rigid insulation boards, gravel and concrete pavers that are loose-laid on top of the waterproof membrane. The authors have...

Wind Performance of Asphalt Roofing Shingles
Pre-seal and post-seal wind resistance of asphalt roofing shingles is discussed. A test method for evaluating pre-seal wind damage is described. Wind tunnel testing results are presented...

Ballasted Single Ply Design Guide Development
A new roofing concept called ballasted single ply has now captured about 25% of the new and retrofit flat roof market. This concept relies on the use of ballast to provide the wind resistance...

Optimum RC Member Design With Discrete Sections
This paper concentrates on the development of simplified yet effective algorithm for optimum reinforced concrete (RC) member design. After constructing the data base of predetermined reinforced...

Wind Resistant Design Manual for Highway Bridges
The new wind resistant design manual for highway bridges has been required recently in Japan. The working group was organized in the Japan Road Association is 1984 to prepare the manual....

Codification of Wind Effects for a Long Span Suspension Bridge
Construction of the Akashi Kaikyo Bridge, which will cross the Akashi Kaikyo Straits with a shore-to-shore of approximately 4 km, started in spring of 1988. Firstly discussions on the...

Status of Structural Engineering Research
Problems and opportunities for structural engineering research are being addressed in a study by the ASCE Structural Division Task Committee on Structural Engineering Research Needs/Funding....

Toward an LRFD-Based AASHTO Bridge Specification
During the 1987 AASHTO Bridge Committee Meeting, recommendations from NCHRP Project 20-7/31 regarding the development of a probability-based LRFD bridge specification were accepted. NCHRP...

Bridge Loading Evaluation for Limit States Design in Japan
Some statistics regarding bridges in Japan are firstly explained. Next, the limit states design which will be introduced in 1995 for highway bridge design specification in Japan is briefly...

Fatigue Life Evaluation of Welded Structural Details in Steel Highway Bridge
Stresses in highway bridge members, fatigue crack propagation behavior and long life fatigue strength properties of welded members under traffic loadings and prediction of fatigue life...

Evaluation of Bridge Safety and Remaining Life
In developed countries, the emphasis on the infrastructure is changing from new construction to the safe maintenance of existing structures. Highway bridges represent an excellent example...

Study and Design of Multi-Span Continuous Bridge
Multi-span continuous bridges which have been constructed in the Metropolitan Expressway Public Corporation are briefly explained. Some studies were carried out into their behavior. The...
