Influence on Steel Deck on Composite Beam Strength
Results of a recent study were described in which 7 push-out tests and 4 composite beam tests were conducted. The results were consistent with other recent studies reported in the literature,...
Composite Beams with Headed Studs in Narrow Ribbed Metal Deck
This paper presents the results of sixteen push-out tests conducted to study the behavior of headed stud connectors in composite beams with narrow ribbed metal deck placed parallel to...
Strength Deterioration Behavior of Concrete-Filled Steel Tubular Beam-Columns
Cantilever beam-columns of steel square hollow section with or without filled-concrete were tested under constant axial load and alternately repeated horizontal load to investigate the...
Perfobond Rib Connectors for Composite Beams
In this paper, the influence of concrete strength, transverse reinforcement and concrete dowels on the capacity of perfobond rib shear connectors is examined. Perfobond rib connector is...
The Behaviour of Reinforced Concrete Beams Manufactured with Side Profile Sheets
The paper describes in qualitative terms the fundamental principles that control the behaviour of a completely new form of construction in which reinforced concrete beams are constructed...
The Pipe/Soil Stiffness Ratio Variable
This paper reviews the factors which affect the reactions and defines performance limitations of buried flexible plastic pipe as a function of load-induced strains and deflections. The...
Ovality in Pipe Rehabilitation Design
Pipes in need of structural rehabilitation often have longitudinal cracks (at the crown and elsewhere) and exhibit significant ovality (5-10%). When these pipes are lined with current...
Microtunneling with PVC Pipe
PVC is a suitable and economical product for sewer system construction. However, in the past, utilization of PVC sewer pipe in microtunneling was impossible due to axial thrust load limitations...
Townsite Lateral-Stage 2 Belle Fourche Unit - Cheyenne Division Concrete: Pipe with Dumped Bedding and Embedment
In 1933, M. G. Spangler presented three bedding configurations and the concept of a bedding factor to relate the supporting strength of buried concrete pipe to the strength obtained in...
Analysis of Pavement-Pipeline Systems After Cut Restoration
The placement of utility pipes normally necessitates many cuts and fills of the existing pavements. Integrity of pipeline and compatible performance of cut restoration and original pavement...
The Load Factor
Spangler's load-factor formula for projecting conduits is generalized to all cases of buried rigid pipe, whether in trenches or under embankments; this is in accordance with the analytical...
Standard Installations: A Synopsis of the ASCE Standard Practice for Direct Design of Buried Precast Concrete Pipe
In 1970, the American Concrete Pipe Association (ACPA) began a long range research program which focused on the behavior of buried concrete pipe. The research resulted in the comprehensive...
Durability of High Performance Concrete
The freeze-thaw durability and the resistance to chloride penetration of high performance concrete (HPC) developed for highway applications were investigated. This paper summarizes the...
Liquefaction Analysis in a GIS Environment
Liquefaction has been identified as one of the seismic hazards that brings great damage to property and infrastructure, and loss of life. The need for liquefaction analysis that works...
Liquefaction Potential of Western Puerto Rico
The historical seismic record, paleoseismic evidence, high population density, time expired since the last major earthquake, and the presence of liquefiable sands and soft clays combine...
Development of Geographical Information System (GIS) for Seismic Hazard Study of Charleston, SC
One of the most prominent areas of seismicity in the eastern U.S. is near Charleston, SC. The 1886 Charleston earthquake (M=7,5) and liquefaction evidence from at least five prehistoric...
A Prospect for Liquefaction Hazard Evaluation Using GIS
A brief description of a recently developed methodology to evaluate liquefaction hazard at a site is presented. In this method, uncertainty and scatter in the data are considered rigorously....
The Proof is in the Pavement
A technique known as statistical quality assurance (SQA) lets DOTs quantify pavement quality by setting statistical guidelines for the work they will accept. SQA is a distinct departure...
Use of High Strength By-Product Gypsum Bricks in Masonry Construction
A new research aimed at producing high strength masonry bricks to be bonded with several types of joint materials other than conventional cement mortar, is introduced in this paper. This...
Use of CLSM Fly Ash Slurry for Underground Facilities
This paper presents the results of research performed in developing and using flowable fly ash slurry which falls under the classification of Controlled Low Strength Material (CLSM) as...
