Pervious Concrete
Pervious concrete consists of a hydraulic cementitious binding system combined with an open-graded aggregate to produce a rigid pavement with typically 15% to 25% interconnected void space....

Evaluation of the Stone Strong Gravity Wall System by Stone Strong Systems: Final Report
This report was prepared as part of the HITEC evaluation for earth retaining systems. This evaluation was performed on STONE STRONG gravity walls, a precast modular wall developed, designed,...

Repair and Rehabilitation of Reinforced Concrete Structures
The State of the Art
Proceedings of an international seminar, workshop, and exhibition, held in Maracaibo, Venezuela, April 28-May 1, 1997. Sponsored by National Science Foundation; Science and Technology...

Swimming in Style
The Deerfield Academy's new $10 million swimming and squash facility, built in the floodplain of a river, is a jewel-box created from glue-laminated timber, galvanized steel,...

Coupling Translation and Rocking Motions
In the design of concrete block foundations for rotating and reciprocating machines, it is important to avoid resonant conditions. Therefore, accurate determination of the frequencies...

Physical Model Tests of Dolos Impact Stresses
An on-going experimental study to determine impact stresses and static nesting stresses in instrumented large scale model dolosse is described in this paper. Seven dolosse were instrumented...

Concrete Shells Today
Providing high structural qualities, modern shells using experimental forms will attract new attention due to their limitless repertory. Presented is a new form of construction, instead...

Performance and Analysis of Frames With URM Infills
The interaction of unreinforced hollow concrete block masonry (URM) infill walls and gravity load designed (GLD) frames has been studied at Cornell University. The primary goal of this...

Wave Run-Up and Reflection on a Permeable Sea Wall
The swash oscillation on a sloping seawall made of step-shaped concrete blocks, waves and water particle velocity in front of the seawall were measured. It was inferred that incident waves...

Alternatives for Overtopping Protection of Dams
Prepared by the Task Committee on Overtopping Protection of the Hydraulics Division of ASCE. This report summarizes the results of an inventory and...

Strength, Behavior and Repair of Masonry Infills
Results of a series of experiments are presented on seismic performance of unreinforced masonry infill panels. The object of the investigation is to examine the loss of out-of-plane strength...

Numerical and Centrifuge Modeling of an Arch Dam on Jointed Rock
This paper addresses the stability of an arch dam built on highly fractured argillite. A large concrete thrust block combined with a wing dam forms the left dam abutment. The last FERC...

Cable-tied Concrete Block Erosion Protection
An articulated concrete erosion protection system is investigated as a possible revetment for bridge piers to be used in place of the traditional rip-rap revetment. The system consists...

Constitutive models
The constitutive models used in the finite element analysis of reinforced concrete structures are presented from a number of different perspectives. The first part of this chapter presents...

Sylvan Beach Pier Rehabilitation Study
The Sylvan Beach Pier is a navigation guide jetty located at the east and of Oneida Lake in Oneida County, New York. It protects the entrance to the New York State Barge Canal which crosses...

Application of a Dolos Structural Design Procedure
Dolos concrete armor units are widely used to protect coastal structures. New developments in armor unit strength design permit the armor unit designer to optimize the dolos parameters...

Behaviour of Prestressed Concrete End Blocks
This paper briefly reports on a series of experiments carried out on strip-loaded prestressed concrete end blocks. The results show that corresponding design methods presently used in...

Durability Failure of a Concrete Block Port Pavement
A concrete block port pavement began showing distress after 7.5 years of use. Initial repair attempts found extensive areas of deterioration. The concrete blocks were cracking, spalling,...

A New Concrete Armor Unit for Breakwaters: The Beta Block
The aim of this paper, is to present a new artificial block for the protection of breakwaters. This armor unit, named BETA, has been designed and tested in the Coasts and Harbors Studies...

Stability of Accropode(R) and Comparison with Parallelepipedic Block
This paper describes the tests which were performed on physical models with irregular waves, to determine the hydraulic stability of the Accropode(R)...
