A Critique of the Ultrasonic Pulse Velocity Method for Testing Concrete
The pulse velocity method is the most widely used ultrasonic nondestructive method for assessing concrete quality. However, it has been well established that the relation between ultrasonic...
Numerical Simulation of Dynamic Shear Transfer
This study was focused on the dynamic response of concrete interfaces under the effects of impulsive loads, and the relationship between the interface shear transfer and the response in...
Simulated Field Trials of Non-Destructive Concrete Test Methods for Highway Structures
The data presented results from a two year Strategic Highway Research Program investigation into suitable NDT methods for determining the early age, and residual strengths of highway structures....
Howdy, Partner
Litigation has long been a nemesis to the construction industry. In recent years, contractors and owners have used innovative alternative dispute resolution (ADR) techniques, such as arbitration,...
Piles Over Problems Sites
It's increasingly difficult to find suitable space for construction in urban areas. Pile foundations can fill the void by making questionable and heavily regulated sites,...
Life in the Fast Track
Through innovative financing and skillful construction management, Oklahoma is proving that transportation megaprojects are still possible, even during an economic downturn. The result...
Project Management: Keys to Success
Successful construction projects can be traced to several key factors observed by the owner, the AE and the contractor. They include: 1) Goals and commitment of the managing partners agreed...
Double Diamonds: New Brand for a Texas Bridge
Double diamond towers, distinctive as a cattle brand but tall as a 44 story building, have reached landmark status on the Texas Gulf Coast even though the bridge they will carry won't...
Automating The Corps
Automated soil testing machines solved several problems at once for the U.S. Army Corps of Engineers' South Western Division Laboratory in Dallas, Texas. The machines replaced...
Adaptive and Parallel Methods for Nonlinear Solid Mechanics
The solution of nonlinear problems, which are of importance to industry and in scientific computations, requires increasing degrees of resolution. This high degree of resolution can be...
Design Cable-stayed Bridge for Cost Effectiveness and Safety
Innovative design approach is needed to enhance the prestigious status enjoyed by cable-stayed bridges. The present paper aims at such a goal of cost effectiveness and safety by providing...
Taylor-Galerkin Method for Wind Wave Propagation
Recently Taylor-Galerkin method has been used to successfully solve advection-dominated flow problems. This method performs quite well in reducing numerical dissipation and numerical dispersion...
On Distributed Processing Applications in Finite Element Analysis
Computer architectures may be classified by the relationship between their instruction and data streams (SISD, SIMD, MISD, MIMD) and the locality of memory (shared, local). Distributed...
Seismic Wave Propagation by Finite Differences on the Connection Machine
Seismic modeling represents a difficult numerical challenge and consumes a significant amount of CPU time on the largest available supercomputers. With the advent of massively-parallel...
On the Role of Experimental Mechanics in Assessing the Performance of Concrete
The role of experimental mechanics in material characterization, design, construction, performance evaluation, repair, rehabilitation and finally destruction of concrete structures is...
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...
Cylindrical Shell Redesign by Large Admissible Perturbations
Redesign (or inverse design) is the problem of defining an objective structural State S2 from its specifications and the known baseline State S1. The large admissible perturbations approach...
Wave Propagation in Fluid Loaded Periodic Structures
Periodic structures, such as rib stiffened plates or cylindrical shells, are frequently used as major structural components in naval and aerospace applications. For these applications,...
Stress Relaxation Analysis for Sealants
A solution method for stress relaxation analysis of systems composed linear viscoelastic material in a state of plane strain is presented. The incremental, finite element method takes...
Nonisothermal Viscoplasticity
A nonisothermal theory of viscoplasticity is formulated for a medium subjected to finite deformation. The basic system of equations consists of the laws of conservation of linear and angular...
