Stress Analysis of the Liner and Liner Anchorage System Near Penetrations in a Reinforced Concrete Reactor Containment
An overpressurization experiment was conducted on a scale-model of a reinforced concrete containment building. The test was terminated when tears formed in the steel liner. Virtually all...
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...
Aerodynamic Modeling of Chimneys
The wake induced acrosswind behavior of circular cross-section structures, such as industrial chimney, has been studied for many years using wind tunnel models. Due to the relaxation of...
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...
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,...
Tuned Liquid Damper and Its Application to Tower-Like Structures
A new kind of damper, Tuned Liquid Damper (TLD) relying upon motion of, shallow liquid in a rigid container for absorbing and dissipating the vibrations energy is explained. The performance...
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...
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...
Seismic Response of Multistory Building Structures With Flexible Floor Diaphragms
An efficient model for three-dimensional analysis of multistory structures with flexible floor diaphragms is proposed in this paper. Three-dimensional analysis of a building structure...
Floor Response Spectra Including Structure-Equipment Interaction Effects
An efficient method for generating floor response spectra with the structure-equipment interaction effects is proposed. Floor response spectra are computed from a prescribed ground response...
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...
Flexural Strength of Ultra-High Strength Concrete Members
Various proposals have been made for the pridiction of strength of high strength concrete sections. One of the most important parts of any strength computation procedure is the assumption...
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...
