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...

SDOF Structural Response Model Accounting for SSI
This paper outlines the theory associated with single-degree-of-freedom (SDOF) structural response models which account for soil-structure interaction (SSI) and evaluates the performance...

Assessment of Transmission Line Foundations
Electric utilities are faced with the need to build new transmission lines or to upgrade existing lines to meet future demands. Because of economic constraints and the difficulty of obtaining...

Structures for Enhanced Safety and Physical Security
This book presents the state-of-the-art in the general subject of structures for enhanced safety and physical security. The technical papers written are by engineers and researchers who...

Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...

Influence of Geologic Development on Horizontal Stress in Soil
Geologic history commonly controls the stress in natural soils, so that an understanding of the geology allows an assessment of the horizontal stress. This paper describes mechanistically...

Cyclic Behavior of Natural Overconsolidated Clay in Two Loading Modes
One-way, stress-controlled, cyclic triaxial compression tests were conducted on a heavily overconsolidated (Ko > 1), slickensided, natural clay with a view to modeling its cyclic...

Collapsible Soils in the Antelope Valley�California
Soils subject to hydroconsolidation, commonly referred to as collapsible soils, have a potential to undergo significant volume reductions upon wetting, with or without additional loading...

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...

Helical Bearing Plate Foundations for Underpinning
Helical anchor foundations have been used in construction to provide resistance against uplift and compressive loading for structures such as transmission towers, tied walls, pipelines,...

Design and Construction of Stone Column Reinforced Cofferdams
A recent expansion of the North Carolina State Port Facility, at Wilmington, involved the use of six cellular cofferdams as earth retaining structures during dredging and final filling...

Concrete Removal Techniques with Potential for Use in Rock
This paper describes concrete removal techniques that were employed in the rehabilitation of US Army Corps of Engineers mass concrete structures and are thought to have potential for limited...

Fracturing of Rock Using Expansive Soundless Chemical Demolition Agents
The theoretical principles of the action of expansive soundless chemical demolition agents are presented. The procedure for using these demolition agents are briefly outlined. Differences...

Static Behavior of Piles in Cemented Calcareous Sands
A series of instrumented jacked model pile tests and another series of uninstrumented grouted model pile tests in a cemented calcareous sand were performed. The influence of pile installation...

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...

Subgrade Models for Soil-Structure Interaction Analysis
Historical development of improvements to Winkler's spring subgrade model are traced. The improvements consist of various ways to provide shear coupling between the springs....

Numerical Analysis of Vertically Loaded Pile Groups
An approach is presented for the analysis of linear and nonlinear response of vertically loaded pile groups. The piles are modeled with finite elements, the pile-soil influence through...

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...
