High-Strength Concrete Joints Under Cyclic Loading
This experimental investigation was undertaken to check the validity for high-strength concrete beam-column joints of recommendations made by ACI-ASCE (American Concrete Institute-American...

Experimental Testing of Laterally Loaded Large Scale Bridge Abutments
The challenges to a bridge analyst in defining abutment boundary conditions and the current state of the practice are presented. Variables within the abutment system are defined and discussed...

Buckling of Cylindrical Storage Tanks Due to Unsymmetric Lateral Wind Load
Non-linear finite element analysis is used to study the elastic stability of cylindrical storage tanks subjected to unsymmetrical loads. These cylindrical shells are assumed to be fixed...

Effects of Earthquake Intensities and Site Conditions on the Reliability of RC Frame Structures
This paper evaluates the effects of seismic zone factors and site coefficients on the seismic reliability of reinforced concrete frame structures. A nine-story intermediate moment-resisting...

Full-Scale Testing of Unreinforced Masonry Infill Frame Panels
This paper presents the results of the out-of-plane testing phase of the National Science Foundation Grant BCS 9102347. This phase of the program addresses the out-of-plane response to...

Out-of-plane and In-plane Testing of URM Infills
This paper summarizes the out-of-plane followed by in-plane quasi-static testing of two, full-scale Unreinforced Masonry (URM) Hollow Clay Tile (HCT) infills. The testing is part of a...

Reliability Analysis of Navigation Structures
Methods for probabilistic stability analyses of concrete monoliths at hydraulic structures were developed and tested. Numerous analyses were performed using data from six actual structures...

Improving Seismic Safety of Dams in California
A search of the dam files at California's Division of Safety of Dams has revealed that at least 94 dams have been improved for seismic stability. The results of the search are tabulated...

Remedial Design and Construction to Improve a Sliding Embankment
The paper describes the studies made to identify the nature of possible remedial measures such as improved drainage, removal of the weak clay layer or a provision of a buttressed dam....

Coolidge Dam Abutment Stability and Stabilization
This paper focuses on left abutment stability assessments and stabilization measures at Coolidge Dam, Arizona. Initial assessment of abutment stability was based on limited rock strength...

Using Innovative Technologies and Geosynthetics in Embankment Dam Rehabilitations
The ever increasing development and confidence in new and innovative technologies such as geosynthetics, in conjunction with often significant economic advantages, have led designers to...

Stability of Embankments, Fills and Structures at the Bad Creek Project Under Static and Dynamic Loading
Duke Power was faced with the problem of using explosives to assist in removing a sensitive, saturated embankment cofferdam supported on a large rock plug. The first phase of the work...

Soil Nailing Technique in Tunnel Support
Authors have developed a new pre-lining method (PASS method) in which thin archshell lining is formed ahead of the tunnel face before the excavation to reinforce the ground. This method...

Guidelines and Recommendations on Shotcrete?An International Compilation
Part of the work within the International Tunnelling Association's (ITA) working group Shotcrete Use has been to compile existing guidelines and recommendations concerning shotcrete, particularly...

Structural Character of the Ghost Dance Fault, Yucca Mountain, Nevada
Detailed structural mapping of an area that straddles the southern part of the Ghost Dance Fault has revealed the presence of several additional subparallel to anastomosing faults. These...

Juanita Creek Channel Restoration?King County, Washington
Juanita Creek, a small basin near Seattle that contains anadromous fish, was experiencing degradation due to urbanization. A detention pond and channel restoration improvements were constructed...

Double Rock Park Stream Restoration Project
The Double Rock Park stream restoration is a pilot project for the Baltimore County, Maryland, Stream Restoration Program. The study assessed watershed conditions and the stream channel...

Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...

The Optimum Parameter Selection for 4-Point Time Domain Integration Schemes
In this paper, a general method of time dimension discretization based on the idea of finite element is presented for dynamic analysis. Two kinds of recurrent formulations are derived...

Application of PC Graphics, CADD, and Solid Modeling Techniques to 3-D Structural Stability of Concrete Monolithic Structures
A computer program for computing 3-D overturning and sliding stability (3DSAD) of concrete monolithic structures has been written and is widely used. This paper describes recent advances...
