Shrinkage Measurements in Composite Beam Slabs
When the concrete slab on a composite beam shrinks, it is restrained by the steel beam to which it is connected. Tensile stresses, as a result, are developed in the restrained concrete...
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...
Micromechanics and Effective Properties of Elastic Particulate Composites
A new micromechanical framework is proposed to investigate the effective mechanical properties of elastic particulate multiphase composites. Exact ensemble-volume averaged field equations...
Damage Dependent Micromechanics in Metal Matrix Composites
A computational approach is used herein to model the effects of processing induced thermal residual stresses on radial, hoop, and shear stresses at the fiber/matrix interface in a continuous...
Micromechanical Characterization of Damage-Plasticity in Metal Matrix Composites
A micromechanical theory of damage mechanics and plasticity is proposed for fiber-reinforced metal matrix composites. The composite system is assumed to consist of elastic, continuous...
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...
Fracture Toughness of DMMC
The fracture toughness of discontinuous metal matrix composites (DMMC) is always less than the fracture toughness of the matrix, in the same heat treatment or annealed condition. If a...
Fracture Toughness Model of Fiber Reinforced Ceramics
This paper addresses the fracture resistance mechanism in fiber reinforced ceramics, and focuses attention on the specific effects associated with the nonlinear nature of the fiber pullout...
Characterization of Granular Material Composite Structures Using Computerized Tomography
The behavior of particulate composites such as asphaltic concrete is controlled by microstructural features including particle and binder arrangements, interparticle contacts, and changes...
Experimental Photoelastic Analysis of Tunnels Containing Cracks
Due to the presence of cracks the strength of the structure is decreased in the present paper an experimental two dimensional photoelastic technique has been developed to analyze the circular...
Basic Aspects of Damage Mesomodelling
The basic aspects of a general damage computational approach which enable to simulate the complete fracture phenomenon are presented. It is a semi-discrete modelling where the material,...
Constitutive Modeling for Material with Perfect Disordered Heterogeneity
Finite element analysis with large number of elements are performed to simulate perfect disordered heterogenous material. The probabilistic nature of the micromechanical behavior of the...
Probabilistic Assessment of Composite Structures
Formal procedures are described which are used to computationally simulate the probabilistic behavior of composite structures. The computational simulation starts with the uncertainties...
A Shear Locking Free Three-Node Triangular Plate Bending Element for Moderately-Thick and Thin Symmetrically Cross-Ply Laminated Plates
A shear locking free three-node triangular plate bending element based on Reissner/Mindlin theory for symmetric general cross-ply laminated plates is developed. The element has total nine...
