Seismic Resistance of Steel Fiber Reinforced Concrete Beam-Column Joints
This paper discusses the advantages of using steel fibers in seismic resistant beam-column connections. First, the effects of fibers on the various aspects of behavior of concrete are...
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...
The Innovative Concept of Semi-rigid Composite Beam
This paper discusses invention and development of a new type of composite beam called 'Semi-rigid Composite Beam.' This new type of beam is expected to behave better than presently used...
Dynamic Response of Variable Height Retaining Walls
A full-scale dynamic test was conducted on a 140 ft long reinforced concrete retaining wall. The observed resonant configurations were similar to those of a cantilever plate and showed...
Analysis of the Seismic Records of a Suspension Bridge
A well-instrumented suspension bridge in Los Angeles, was shaken by the October 1, 1987 Whittier earthquake (ML = 5.9). This study addresses the...
Field Measurements of Wind-Induced Pressures on Roofs of Low Buildings
Full-scale measurements have been carried out on an experimental building, 3.3 m high, beside the football field at the Loyola campus of Concordia University. Wind-induced pressures have...
Site Load Testing of Full Scale Composite Concrete Floors
The paper presents the results of a load test carried out in 1982 on a continuous reinforced concrete slab with a permanent shuttering consisting of compressed straw (Stramit) or cement...
Ambient Vibration Response of a Long Span Bridge
Natural frequencies, mode shapes and damping characteristics for a long-span cable-stayed bridge were experimentally determined from a series of ambient vibration tests for both the cantilever...
Instrumentation Considerations for Nondestructive and Destructive Testing of Reinforced Concrete Slab Bridges
This paper examines the process of selection and calibration for instruments used in nondestructive and destructive field tests of a reinforced concrete slab bridge. Of great importance...
Remote Monitoring of a Stressed Timber Bridge Deck
The long term behavior of a CCA treated stressed timber deck bridge is being monitored, at present, using a remote data acquisition system. The bridge which is located in Gray, Maine was...
Monitoring Performance of Full Scale Structures
General Physics Services Corporation (GPSC) of Columbia, Maryland has developed a device for the remote long-term monitoring of full scale structures, such as highway bridges. This patented...
Full Scale Dynamic Monitoring of Highway Bridges
Sensitivity of identified modal properties by physical testing is critical for automated monitoring of bridge structural condition. It is investigated here considering flexure modes and...
In Situ Testing Performed at Jackson Lake Dam
Jackson Lake Dam was rehabilitated from 1986 to 1988 to increase seismic stability. Final foundation improvements consisted of dynamic compaction and mixed inplace soil cement columns....
Risk-Based Methodology for Seismic Rehabilitation of Earth Dams
A methodology for seismic risk analysis of earth dams is described. The procedure utilizes seismological and geotechnical inputs together with the associated uncertainties and provides...
Construction of CCM Overtopping Protection on Three Parkway Dams
Cellular concrete mat (CCM) systems have been installed as overtopping protection on three small embankment dams along the Blue Ridge Parkway. Based on field tests by others and on the...
Bond Stress Test on Rock Anchor in Clayey Siltstone
Seventy five rock anchors with design loads of 556 to 2040 kips were required for the 1000-foot long, 125-foot high, concrete gravity, Lake Lynn Dam to comply with current FERC engineering...
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...
Development and Evaluation of Remediation Strategies by Deformation Analysis
Deformation analysis is providing guidance for the most efficient and economical seismic remedial treatments for Mormon Island Auxiliary and Sardis dams. The computer program TARA-3FL...
Seismic Stabilization of St. Joe State Park Tailings Dams
Tailings dams constructed by the `upstream' method are known to be seismically vulnerable, but field experience indicates that their seismic stability usually improves following termination...
