An Overview of the Round-Robin Analysis of the 1:6-Scale Reinforced Concrete Containment Model
The results of nonlinear structural analyses of a 1:6-scale reinforced concrete model, which were independently conducted by ten different organizations, are briefly described and compared...
Development of a Test Validated Methodology for Predicting Concrete Containment Leakage
In the past several years, considerable research effort has been devoted by the Electric Power Research Institute and the U.S. Nuclear Regulatory Commission to the behavior of reactor...
Strength Evaluation of Existing Reinforced Concrete Structures
The load test as described in ACI 318-83 Chapter 20, entitled 'Strength Evaluation of Existing Structures,' was conducted at 60%, 80%, and 100% of the calculated...
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....
Fourier Series Expansion on Determination of Response Bound of Beam
Fourier series expansion is suggested to discrete the continuous vibrating system by regarding Fourier constants as generalized displacement parameters. The orthogonal merit to the terms...
Inelastic Response of Buried Pipelines Due to Landslide Effects
During earthquakes, a buried pipeline may experience significant loading as a result of large relative displacements of the ground along its length. Large ground movements can be caused...
Dynamic Response of a Building with Dual System
The paper presents the dynamic response of a 30-story building with dual system consisting of cross-bracing and beam-column moment resisting frames. Two types of beam-column connections,...
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...
A New Proposal of Design Wind Loads for Beams Supporting Long-Span Roofs
The wind tunnel testings of wind pressures acting on long-span roofs are carried out. Dynamic wind pressures are measured simultaneously at a lot of points on the roofs. The instantaneous...
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...

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...
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...
Load and Resistance Factor Design for Engineered Wood Construction
The wood industry has provided sponsorship for the development of a reliability-based, load and resistance factor design specification for engineered wood structures. This user-tested,...
Load Combinations for LRFD With Wood Construction
Probability based limit states design for wood construction is complicated by the fact that wood is a natural material with large variations in mechanical properties and is sensitive to...
LRFD for Engineered Wood Construction: Calibration to Current Design
The structural design code for engineered wood construction is evolving to a limit state design basis in which the safety checks are derived from the underlying probability distributions...
