Predictions of Pile Shaft Capacity With the PLS Cell
In situ measurements of stresses and pore pressures on a model pile shaft, the Piezo-Lateral Stress (PLS) cell, are utilized to reconstruct the conditions of load tests involving two large...
The DMT - ?hc Method for Piles Driven in Clay
This paper presents a tentative method for evaluating the limiting skin friction f//s for piles driven in clay based on sigma //h'c (horizontal effective stress at the interface...
Determining Sand Strength by Cone Penetrometer
Evaluation has been made of several theories and methods for deducing sand strength from cone resistance. Bearing capacity theories, cavity expansion theory, and empirical methods have...
Bearing Capacity of Footings on Clay CPT Method
A method is proposed to predict the ultimate bearing pressure for footings on clay using data from cone penetration tests. This method relates the ratio of ultimate soil bearing for a...
Fast, Economical, Cone Testing of River Sediments
The objective of the study reported was to obtain quantitative geotechnical information over many square miles of Hudson River bottom. A hand held cone penetrometer was selected for use....
Reviewing for Potential Failure
The key to preventing structural failures is to examines them and develop systematic techniques for avoidance. One, called contingency analysis, starts with a what if process to decide...
Factory Chic
Developers of the International Design Center of New York have recently spent $163 million to convert an unused chewing gum factory and a former battery plant into a showcase for New York...
A Microcomputer Program for Bearing Capacity Analysis
The objective of this paper is to introduce an IBM/PC/XT/AT microcomputer program for the Bearing Capacity Analysis of Shallow Foundations. The program incorporates the bearing capacity...
Interactive Microcomputer Analysis and Design of Light Gage Steel Roof Systems
A hinderance to the widespread acceptance of the cold-formed steel roof Z-purlin in conventionally engineered buildings is due to the lack of a useful and efficient analysis and design...
New Generation Capacity
Currently, electric utilities in the U. S. have excess generation capacity. In addition, some new generation capacity is well under construction and is scheduled to come on-line soon,...
Research Challenges in Frozen Ground Pile Design
A fairly recent pile design analysis is reviewed. The influence of such factors as temperature, salinity, loading, etc. on frozen ground pile design is pointed out. Since many facets of...
Standards for Pile Load Tests in Permafrost
A requirement exists to establish standard procedures for conducting pile load tests in permanently frozen soils. The methods outlined in the ASTM Standards for piles in thawed soils do...
Geotechnical Behavior of Underreams in Pleistocene Clay
Enlarged bases are often constructed in cylindrical drilled-and-cast-in-situ foundation elements (footings, bored piles) to increase their capacity. Enlarged bases that are cut mechanically...
Comparison of Caisson Load Tests on Chicago Hardpan
The results from two relatively recent instrumented caisson load tests from different sites on Chicago Hardpan are compared with a 'classic' large scale caisson...
Review of Repeated Axial Load Tests on Deep Foundations
A review of the literature is presented on the axial capacity of deep foundations subjected to repeated loads. Data are summarized on anchors, driven piles, and drilled shafts. In general,...
Load-Carrying Capacity and Remaining Life of First-Built Composite Girder Bridge in Japan
Kanzaki Bridge, Osaka, Japan, was the first steel-concrete composite bridge built in 1953 to carry the Osaka Prefectural Road over Kanzaki River. The bridge was removed in 1978 after 25...
Timber Bridge Decks
The portion of the nation's 500,000 bridge decks that are made of timber has been declining for years, as the old timber ones on secondary road bridges are rebuilt, in most...
A Carrying Capacity Study of Hatteras Island
This article summarizes a study done of Hatteras Island, North Carolina, a largely undeveloped and natural barrier island. 'Carrying capacity' means the ability...
Reliability Analysis of Water System Capacity
The paper presents, by means of an application, a few promising analytical methods for estimating bulk water system capacity reliability. In particular, this paper examines the applicability...
Load-Bearing Capacity of Masonry Walls in a Critical Buckling Condition Taking Into Account the Restraining Effect of Floor Slabs
This paper studies the buckling effect of masonry walls and concrete floor slabs as a frame system. The frame is calculated according to the theory of II. order. The buckling length, the...
