Field Examination of a Distribution System Water Quality Model
In the aftermath of the Safe Drinking Water Act (SDWA) of 1974, numerous models have been established to assess the quality of water and simulate its deterioration in distribution systems....
The EUR Water Station in Rome?Italy
The paper deals the new steel Water Centre realized by ACEA in Rome. The Water Station is destined to manage the water consumption of around 500,000 inhabitants with an output of 3,900...
Vortex Spillway: Test Study on a Hydraulic Model
The paper deals with an experimental study on a model of the forced vortex of Eur hanging reservoir realized by ACEA (Rome). Some vortex characteristics are investigated and, in particularly,...
Optimizing Water Transfers in Urban Water Supply Planning
A number of water supply agencies in the Western United States have begun to integrate water transfers into their overall water supply planning, including the use of transferred water...
Hydraulic and Water Quality Reliability and Resiliency for Water Distribution Systems Under Random Demands
This paper develops a preliminary method to evaluate the reliability and resiliency of water distribution systems under random spatial and temporal demand patterns, including random fire...
Three-Dimensional Modeling of the Coastal Region Offshore from Sydney, Australia
Care must be taken in model formulation to ensure that unwanted internal circulation cannot be induced. Extensive model testing must be carried out on possible distorted element shapes...
GIS and SWMM Applications in Developing the Lake Houston Watershed Management Program
The City of Houston has undertaken the task of developing a Watershed Management Program for the 2,828 square mile lake Houston Watershed in an effort to prevent future degradation of...
New York Bight Three-Dimensional Water Quality Model
The numerical modeling technology developed for Chesapeake Bay was applied to the Middle Atlantic Bight extending 550 km form Cape May, NJ, northeasterly to Nantucket Island, MA, and extending...
Serviceability Stress Limits for Composite Beams
Serviceability limits are increasingly becoming the critical design requirement for composite beams. A set of three illustrative design studies indicates that this is particularly true...
Connection of Grouted Tubular Insert Piles to Soil
Force transfer between offshore production jackets and tubular piles is effected by weld bead shear connectors, acting within the grout filled annulus between the piles and pile sleeves...
Design of Composite Slabs for Vertical Shear
Three major modes of failure should be considered in the design of the positive moment regions of composite slabs incorporating profiled steel sheeting, viz.: flexure, longitudinal slip...
Interaction of Steel Structure and Composite Supercolumns in Spine Structures
Modern architecture has departed from uniform rectangular cigarette boxes for high-rise buildings. A structural system which goes uninterrupted through the common denominator of the varying...
Cyclic Lateral Load Analysis of Composite Frames
A method of analysis for composite building frames subjected to repeated and reversed lateral loads has been developed as part of an overall investigation of seismic response of composite...
Semi-Rigid Joint Action in Composite Frames: Numerical Analysis and Design Criteria
The paper focusses on the analysis of semi-rigid composite frames, reporting mainly on the results of a research study which combines the experimental and theoretical approaches. Attention...
Investigation of Corners and Joints Applied to a Steel-Concrete Composite Caisson
We have developed a caisson composed of steel-concrete composite slabs and steel structures, which we call a `Hybrid Caisson.' We studied the structural principles and usability of the...
Composite Columns Subjected to Bending and Shear
This paper describes experimental as well as analytical studies of the post elastic deformation and fracture behaviors of wide flange steel encased reinforced concrete (SRC) composite...
Full-scale Tests on Composite Connections
Tests have been carried out on eight full-scale composite connections in which the columns were manufactured of concrete-filled steel circular hollow sections (CHS). The connections were...
Hybrid Lifted Structure for the Collserola Tower
The structure of the 300 m. Collserola Tower is a hybrid system formed by three combined structural systems consisting of: - a very slender cylindrical concrete shaft: - a large steel...
Strength and Stiffness Behavior of Composite Steel Grid Decks
This paper briefly discusses the historical development of composite steel grid decks. The static and fatigue behavior under bending of filled and unfilled steel grid decks (exodermic)...
Behavior of Concrete-Filled Steel Tubular Three-Dimensional Subassemblages
Three-dimensional subassemblages consisting of a concrete-filled steel tubular column and four H-shaped beams were tested under a constant axial load on the column, constant beam loads...
