Smooth Static And Dynamic Indentation Of A Cantilever Beam, Minggang Zhou, William P. Schonberg Dec 2001

Smooth Static And Dynamic Indentation Of A Cantilever Beam, Minggang Zhou, William P. Schonberg

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The static and dynamic indentation of structural elements such as beams and plates continue to be intriguing problems, especially for scenarios where large area contacts are expected to occur. Standard methods of indentation analyses use a beam theory solution to obtain an overall load-displacement relationship and then a Hertzian contact solution to calculate local stresses under the indenter. However, these techniques are only applicable in a fairly limited class of problems: the stress distribution in the contact region will differ significantly from a Hertzian one when the contact length exceeds the thickness of the beam. The indentation models developed herein …

Practical Issues For The Application Of High-Performance Concrete To Highway Structures, John J. Myers, Yumin Yang Nov 2001

Practical Issues For The Application Of High-Performance Concrete To Highway Structures, John J. Myers, Yumin Yang

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In recent years, the advantages of high-performance concrete (HPC) have been well documented. Among others, these advantages include enhanced design flexibility and improved durability performance that results in reduced maintenance costs and an increased service life. Despite these obvious benefits, the implementation of HPC has been very slow. This can be attributed to several factors including the uncertainty related to current design codes and a lack of familiarity of designers and contractors with practices and requirements for proper design and construction of high-performance concrete structures. This paper introduces and discusses several fundamental issues that affect the implementation of HPC and …

Pilot Study: Lateral Braced C-Sections Under Bending, B. Beshara, Roger A. Laboube Oct 2001

Pilot Study: Lateral Braced C-Sections Under Bending, B. Beshara, Roger A. Laboube

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The overall behavior under uniform load of cold-formed steel C-sections assemblies was investigated. Each test assembly consisted of C-sections acting as beams having a track section to restrain its ends. A lateral brace to restrain the C-sections from rotation was provided at mid-span. To better understand the influence of the brace on the flexural behavior, an experimental investigation was carried out with particular emphasis placed on the study of the effect of the mid-span brace connection when wallboard was attached to the tension flange. The tested moment capacities are compared to predictions based on the 1996 edition American Iron and …

Evaporative Cooling Availability In Water Based Sensible Cooling Systems, Ben Costelloe, Donal Finn Sep 2001

Evaporative Cooling Availability In Water Based Sensible Cooling Systems, Ben Costelloe, Donal Finn

Conference Papers

Recent developments have prompted a review of evaporative cooling technology as an effective means of cooling modern deep plan buildings. Prominent among these developments is the success of high temperature sensible cooling systems, such as chilled ceilings, which require a supply of cooling water at 14 to 18°C. Crucial to the success of evaporative cooling technology, as a significant means of cooling in modern applications, is the ability to generate cooling water, in an indirect circuit, at a temperature which closely approaches the ambient adiabatic saturation temperature or wet bulb temperature. Recent research in this area has shown that it …

Strain Rate And Aging Effect On The Mechanical Properties Of Sheet Steels, Chi Ling Pan, Shaojie Wu, Wei Wen Yu May 2001

Strain Rate And Aging Effect On The Mechanical Properties Of Sheet Steels, Chi Ling Pan, Shaojie Wu, Wei Wen Yu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

This study was primarily involved with the experimental determination of the dynamic mechanical properties of five different sheet steels. The nominal yield strengths of these five types of sheet steels ranged from 172 to 690 MPa (25-100 ksi) and the range of strain rates varied from 10-4 to 1.0 mm/mm/s. All these five materials were studied in both longitudinal and transverse directions under various strain rates, and some materials were also tested under different strain rates and different amounts of prior cold stretching. In addition, two types of steels were tested to estimate the aging effect on the mechanical properties …


Asymmetric Low-Velocity Impact Of A Finite Layer, Minggang Zhou, William P. Schonberg May 2001

Asymmetric Low-Velocity Impact Of A Finite Layer, Minggang Zhou, William P. Schonberg

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The dynamic indentation of structural elements such as beams and plates continues to be an intriguing problem, especially for scenarios where large area contacts can occur. Standard methods of indentation analysis typically use a dynamic beam theory solution to obtain an overall load-displacement relationship and then a Hertzian contact solution to determine local stresses under the impactor. However, previous static and dynamic modeling efforts have shown that the stress distribution in the contact region will differ significantly from a Hertzian one when the contact length exceeds the thickness of the beam. In such cases point contact can no longer be …


Diagnostic Load Testing Of Two-Way Posttensioned Concrete Slab, Antonio Nanni, M. Mettemeyer May 2001

Diagnostic Load Testing Of Two-Way Posttensioned Concrete Slab, Antonio Nanni, M. Mettemeyer

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Diagnostic load testing techniques have been used to verify in situ that existing structures have the required load-carrying capacity. This paper discusses the diagnostic load testing and finite-element modeling of a two-way posttensioned concrete slab with the purpose of illustrating the features of this full-scale testing method. The slab was modeled using a commercial finite-element package and the results were verified experimentally. The test loads were applied using hydraulic jacks. Negative internal bending moments were generated at critical locations equivalent to those produced by a 92 psf (4.40 kPa) superimposed uniformly distributed load. Positive internal bending moments were also produced …


Self-Monitoring, Pseudo-Ductile, Hybrid Frp Reinforcement Rods For Concrete Applications, C. E. Bakis, Antonio Nanni, J. A. Terosky, S. W. Koehler May 2001

Self-Monitoring, Pseudo-Ductile, Hybrid Frp Reinforcement Rods For Concrete Applications, C. E. Bakis, Antonio Nanni, J. A. Terosky, S. W. Koehler

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The feasibility of hybrid -fiber-reinforced-polymer rods that demonstrate the important safety features of self-monitoring capability and pseudo-ductility is demonstrated. The rods are intended to be the basis of improved pultruded reinforcements for concrete or other civil applications where safety is of critical importance. The lowest elongation fiber in the seven rods investigated is carbon, which by virtue of its piezo resistivity allows the monitoring of deformation and fracture throughout an entire rod with simple electronic equipment. Resistance measurements obtained during quasi-static tests clearly reveal failure of the carbon fibers. Following this easily detected event, higher loads can be safely sustained …


Characterization Of Frp Rods As Near-Surface Mounted Reinforcement, Laura De Lorenzis, Antonio Nanni May 2001

Characterization Of Frp Rods As Near-Surface Mounted Reinforcement, Laura De Lorenzis, Antonio Nanni

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The use of near surface mounted (NSM) fiber-reinforced polymer (FRP) rods is a promising technology for increasing flexural and shear strength of deficient reinforced concrete (RC) members. As this technology emerges, the structural behavior of RC elements strengthened with NSM FRP rods needs to be fully characterized. Given the variability of material properties and groove geometry, this requires that the tensile properties of the FRP rod and the mechanics of load transfer between NSM FRP rods and concrete be investigated. Tensile and bond tests on commercially available carbon FRP deformed rods for application as NSM reinforcement were carried out using …

Yield Moment Of Cold-Formed Steel Beams Under Different Strain Rates, Chi Ling Pan, Wei Wen Yu Mar 2001

Yield Moment Of Cold-Formed Steel Beams Under Different Strain Rates, Chi Ling Pan, Wei Wen Yu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

It has been recognized that the mechanical properties of sheet steels and the structural strength of cold-formed steel members can be influenced by strain rate. For studying the local and post buckling behavior of stiffened and unstiffened compression elements under a dynamic loading condition, 60 beams, which were assembled from the same material, have been tested under different strain rates. To study the structural behavior of hybrid cold-formed steel beams, a total of 72 specimens was investigated. The results showed that the strength of beams increases with increasing strain rates. The amount of increase was found to be dependent on …
