Original Formulation of the Finite Element Method
Following a brief summary of the 1952 state of the art of structural analysis, the paper describes the circumstances that led to the formulation of the finite element method by members...

Major Advances in Finite Element Model Technology
The evolution of finite elements is traced from the viewpoint of finite element shape functions and element-related techniques. Particular emphasis is placed on the isoparametric element,...

Parallel Computations for Automated Finite Element Modeling
This paper discusses initial efforts to combine an automatic mesh generator and element by element solution approaches to produce efficient parallel computational procedures on adaptively,...

High Strength Concrete: Proportioning, Behavior and Applications
Generally, concrete with a cylinder compressive strength higher than 6000 psi (41.4 MPa) is designated as high strength concrete. High strengths are achieved using stronger coarse aggregates,...

NDE for Performance of Wood Structures
Significant economic losses result annually due to deterioration and failure of structural wood components. A high percentage of these losses result from our current inability to assess...

High Molecular Weight Methacrylate for Sealing Cracked Concrete
The sealing of cracks in concrete surfaces has been one of the most difficult types of repair to accomplish. Epoxy injection has been widely used, but due to its relatively high cost,...

Use of Copper Slag for Construction Purposes
Standard laboratory test results on the fine- and coarse-grained fractions of a copper slag have been presented. Based on the results of these tests, the possible use of the fine fraction...

Sprayed-On Polymer Mortar Construction
Sprayed-on polymer mortar has been used to construct low-cost, lightweight structures in a variety of locations. The addition of the two-component additive to one cubic yard of mortar...

Concrete Strength-Quality Assurance
The usual criterion for establishing grades of structural concrete is the compressive strength measured in an arbitrary manner on a standardized specimen stored in a stipulated fashion...

Lessons Learned in Laboratory and Field Evaluation of Accelerated Strength Tests for Quality Control of Concrete Pavements
This paper describes the results of an accelerated strength testing program performed to evaluate flexural strength potential at 28- and 90-days. Based upon a literature review of previous...

Compressive Deterioration of Cracked Concrete
When shear behavior of reinforced concrete (R/C) members is to be simulated, the compressive strength and the stiffness reduction of cracked concrete must be taken into consideration....

Ultimate Strength and Deformation of RC Panels
In this study, twenty reinforced concrete panels have been tested under pure shear. Test results showed that the compressive strength of concrete strut was strongly affected by bond characteristics...

Parametric Analyses of RC Shear Walls by FEM
In this paper, nonlinear behavior of reinforced concrete shear walls is studied by using the finite element analysis. We applied numerical analyses to a wide range of parameters, such...

Flexural Strength of Ultra-High Strength Concrete Members
Various proposals have been made for the pridiction of strength of high strength concrete sections. One of the most important parts of any strength computation procedure is the assumption...

In-Plane Behavior of Concrete Masonry Coupled Walls
To study the in-plane seismic resistance of multi-story masonry coupled walls, 6 full-scale reinforced masonry specimens, each two stories high, are being constructed and tested in the...

Amelioration of Stirrup and Compression Reinforcement on the Ductility of Reinforced High-Strength Concrete Beam
18 rectangular high strength concrete beams were tested to investigate their ductile behavior. The results show that it will be more advantageous, for ductility, to choose the compressive...

Tension Leg Platform
a State of the Art Review
Prepared by the Task Group on Compliant Offshore Platforms of ASCE. This report considers the analysis and design of tension leg platforms (TLPs),...

Some Dilatometer Test Results in Pennsylvania and New York
This paper starts with a brief introduction to the dilatometer and piezoblade. Test results in four different areas are presented. DMT soundings at LR 67057 (Legislative Route numbers...

Cyclic Behavior of Natural Overconsolidated Clay in Two Loading Modes
One-way, stress-controlled, cyclic triaxial compression tests were conducted on a heavily overconsolidated (Ko > 1), slickensided, natural clay with a view to modeling its cyclic...

First-Order Estimation of K_o in Sands and Clays
The in-situ horizontal stress coefficient (K_o) is known to be the dominant design parameter controlling the side resistance of deep foundations....
