In-Situ Determination of the Compressive Stress-Strain Relationship of Multi-Wythe Brick Masonry
In-situ stress-strain relationships of existing multi-wythe brick masonry have been determined by introducing flatjacks into sawcuts made in the exterior wythe of the multi-wythe masonry....
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...
Design of Built Up Compression Members for Long Span Bridge Structures
This paper discusses the design of built up compression members for long span bridge structures including trusses and arches. Provisions of load factor design and use of high strength...
Creep and Shrinkage of Composite Columns in Tall Buildings
The simultaneous presence of steel and composite columns in tall buildings is a common occurrence. The axial shortening characteristics of composite columns are influenced by creep and...
Performance and Serviceability of Composite Floors
Concrete slabs on steel deck are the most common type of floor system in use today. This system of construction is particularly advantageous when ultimate strength design (LRFD) is used....
Vibration of Composite Floors
An AISC/CISC guideline on floor vibration is being prepared to help practitioners design to avoid floor vibration problems and to remedy problems that occur in practice. This paper provides...
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...
Vibration and Impact in Skewed Steel Bridges
The vibration and impact of skewed multigirder bridges due to vehicles moving across rough bridge deck are studied. The bridges are modeled as grillage beam systems. The vehicle is simulated...
Steel Bar Joist Performance: Design Deficiencies and Defects
Several failures of steel bar joist roofs have been investigated by the authors in the past decade. Many of these failures or performance problems have corresponded to bar joists manufactured...
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...
How to Include Reliability Constraints in Structural Optimization
Structural optimization is a complex process made of design cycles aimed at finding the best possible solution. At each design cycle ultimate and/or serviceability limit states must be...
Development in Criteria for Dam Corrective Actions
Reviewed is the recent history of the Bureau of Reclamation (Reclamation) Safety of Dams (SOD) Program. Particularly, the development of decision philosophies and technical approaches...
Embankment Dam Safety
Procedures for identification and evaluation of conditions which can lead to catastrophic dam failure through either piping or deep seated instability of the downstream surface are presented....
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...
Testing and Evaluation of High Capacity, Multi-Strand Rock Anchors for Lake Lynn Dam
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...
The Douglas Dam Emergency Response and Rehabilitation
Through the timely response of the Owner, the potential failure of Douglas Dam was averted, and lives and property downstream were protected. The economic losses created by loss of irrigation...
The Use of Post-Tensioned Anchorages on the Arch Portion of Stewart Mountain Dam, Arizona
Post-tensioned rock anchorages were selected by the Bureau of Reclamation (Reclamation) to stabilize Stewart Mountain Dam against potential seismic loadings. The use of such anchorages...
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...
