Bond and Dowel Action of a Main Bar in a RC Beam
The bond and dowel action are analytically treated independently on each other in most cases. The bond behavior may be, however, much affected by the dowel action in structural members....
Architectural Configurations in Vina del Mar
This paper identifies the architectural characteristics of 121 reinforced concrete buildings in Vina del Mar. These characteristics are related to the damage statistics for the building...
Comparison of Slitted and Non-Slitted R. C. Shear Walls With Boundary Elements Under Horizontal Forces
This paper compares the differences of aseismic behaviours between slitted and non-slitted shear walls under horizontal forces. There are 5 specimens for slitted shear walls and another...
Seismic Strengthening of a Tall Masonry Building
The design of a strengthening system for a tall building is proposed using ductile reinforced masonry shear walls. This innovative design concept produced a system that controlled the...
Development of Inelastic Reduction Factors to Provide an Elastic Design Procedure
R factor values can only be rationally selected when they are based on in part nonlinear inelastic dynamic analyses of building system types. However, it is informative to discuss the...
Recent Developments in Testing Base Isolation Systems
One of these developments has been the ability to test large scale isolation systems using simulated seismic loads. These tests have not only proven the performance and reliability of...
Characterization of a Site Underlain by Deep Collapsing Soils
The geomorphic setting of a site underlain by an 80 ft (24 m) deep deposit of collapsing silty sand is described. The field and laboratory investigation completed to characterize the geotechnical...
Rock Excavations in Downtown Toronto
The geology of Toronto area is somewhat complex due to the series of advances and retreats of the glaciers. The overburden deposits consist of materials laid down during the Wisconsinan...
Numerical Modeling of Interface Behavior for Drilled Shaft Foundations Under Generalized Loading
To evaluate soil-foundation interaction numerically, an isoparametric thin layer element is used within a 3-D, material nonlinear, general purpose geotechnical analysis system developed...
Investigation and Modeling of Soil-Structure Interface Properties
An investigation of some techniques suggested to reduce friction at the soil-structure interface, for example plastic sheet on sand, is presented, and a model proposed for characterizing...
Fact or Friction: A Review of Soil Response to a Laterally Moving Pile
A review of soil response around a laterally moving pile is presented and 'Winkler' spring soil modulus variations are discussed. Based on available theory, and...
Ultimate Capacity of Deep Foundation by a Rigid-Plastic Analysis
This paper is concerned with the determination of the axial ultimate capacity of a rigid pier on the basis of the theory of perfect plasticity. As an application of the upper bound theorem...
Analysis of Drilled Shafts in a Deep Fill
A deep fill of varying thickness will settle with time and will also exhibit a horizontal component of movement. Drilled shafts that are installed in the fill to support a structure must...
Special Bedrock Conditions and a Foundation Project in Greater Boston
In the greater Boston area the argillite bedrock and/or the overlying glacial till provide suitable support for a wide range of foundation systems, including high capacity end-bearing...
Thoughts on the History and Current Practice of Foundation Engineering in North America
With the publication of 'Erdbaumechanik' in 1925, the behavior of soils was explained in terms of numerical physical properties and the principles of what became...
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...
Erosion and Washover in Coastal Louisiana
In 1985 three hurricanes affected the barrier coastline (Caminada-Moreau Headland) of Louisiana. These produced severe coastal erosion and rapid washover extension. Using the 1979 U.S.G.S....
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...
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...
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...
