This paper provides an overview of the state-of-the-art publication on the same subject under preparation by ASCE-ACI Committee 442's Ad Hoc Subcommittee on Inelastic Response...

Inelastic Seismic Analysis of Concrete Buildings
The important inelastic analysis techniques that are suitable for concrete buildings subjected to earthquakes are summarized. Basic principles and practical modeling guidelines are given...

Bermed Shelters Subjected to Accidental Explosions
An investigation of the adequacy of two competing shelter designs to protect the occupants from an accidental explosion in a nearby shelter is described. Two bermed shelters, one of rectangular...

Residual Capacity of Explosively Damaged Reinforced Concrete Columns
The results of load tests on explosively damaged reinforced concrete columns are presented. The method used to correlate an ultimate strength, laminar type of reinforced concrete analysis...

Structural Resistance of Slabs for Blast Loading
Results from a series of static tests on one-way reinforced concrete slabs are summarized. The slabs were loaded with a uniform pressure and tested to large deflections. Parameters varied...

Reevaluation of Reinforced Concrete Slabs Subjected to Blast Effects
Failures in reinforced concrete shallow-buried structures subjected to the effects of severe dynamic loads are reevaluated by employing a modified Timoshenko beam formulation which includes...

Transient Dynamic Response Analysis of Embedded Rigid Foundations
A simplified approach for the transient dynamic response analysis of embedded multiple rigid foundations is presented. The approach is based on approximate time-domain formulations of...

Subgrade Model for Static and Dynamic Response Analysis of Surface Foundations
A new subgrade model is presented for the static and dynamic response analysis of surface foundations. The model consists of a number of horizontal layer model units. Each model unit is...

Foundation Studied for Turbine-Generator on Liquefiable Soils
Turbine-generator foundations are generally constructed of concrete in the U.S.A. This paper deals with the dimensioning and evaluation of a turbine foundation in Oxnard, California. The...

Bearing Pressure?SPT Correlations for Expanded Base Piles in Sand
Design of enlarged base piles is usually carried out using correlations between SPT N values and point resistance. The results of full scale load tests are used to show that base resistance...

Analysis of Barrier Island Dynamics for Ship Channel Planning at Ship Island, Mississippi
Ship Island is located among a chain of barrier islands approximately 18 km south of Biloxi, Mississippi. During initial construction of Gulfport Harbor Ship Channel, 1901-1905, the channel...

In Situ Determinations of Dispersion and Transport Parameters at Piraquara De Fora (RJ)?Brazil, With Help of a Fluorescent Dye Tracer
This paper deals with 'in situ' determinations of the transport and dispersion parameters at Piraquara de Fora cove, near the site where the first Brazilian nuclear...

Countering Terrorist Threats
Musacchio & Rozen assessed the risks and vulnerabilities to a possible terrorist attack of the data processing center of a large European bank. With the increasing use by terrorist...

Structural Design, Analysis and Testing
This volume contains the papers presented in 21 sessions of the 1989 Structures Congress held in San Francisco. The papers cover a wide range of topics including types of construction...

Convection in the Classroom
By their nature, the empirical relations used to calculate convective heat transfer coefficients offer the user little or no insight into how the typical input parameters, e.g., pipe diameter...

Interactive Aircraft Section Calculations for Drag
Large interactive computer programs are being called upon with increasing frequency for the preliminary and conceptual design of aircraft. One drag component which can be estimated at...

Computerized Dynamic Human Factors Mannequins Assess and Create Products and Environments for an Aging Population
A PC-based human factors symbol library helps make designs accessible to a broad populace. The system and research results described were developed in three phases. Knowing that in order...

Application of Field Proven Fine Bubble Membrane Aeration Technology
Fine bubble membrane diffusers represent a significant technological advancement in diffused aeration technology by providing the consistently high transfer efficiencies of fine bubble...

Radon Resistant New Construction Practices
This paper highlights the basic principles for building radon-resistant houses and it groups the construction techniques into four categories, i.e., the barrier approach, soil ventilation...
