On the Inelastic Design of Steel I Girder Bridges
This paper documents the development of a relatively easy to use set of effective plastic moment expressions and compares the performance of these equations with a series of experimental...
Structural Lumber from Small-Diameter Western U.S. Softwood Trees
The purpose of this study was to determine the mechanical properties, and corresponding economic value, of dimension lumber produced from selected over-stocked forest stands of small-diameter...

Inelastic Response of Metal Matrix Composite Tubes
An analytical method which exactly satisfies the equations of the boundary value problem for the inelastic response of laminated metal matrix composite tubes on a point-wise basis is presented....
The Inelastic Response of an Offshore Platform in Hurricane Andrew
Amoco's Gulf of Mexico South Timbalier 161A platform took a direct hit from Hurricane Andrew in August of 1992, experiencing loads which far exceeded its design load. The platform had...
Case Study - Performance of Diaphragm Walls During Construction; Predictions vs. Field Measurements
Rigid diaphragm walls (slurry walls) are being used more than any other earth supporting system for underground construction projects in confined downtown sites throughout the United States...
Effects of Site Conditions of Earthquake-Resistant Design of Structures
After a brief discussion of the importance of reliable establishment of design Earthquake Ground Motions (EQGMs) for efficient Earthquake-Resistant Design (EQ-RD) of structures, this paper...
A Self-Balancing Laminate
A self balancing wood laminate has been developed based on the principle of orthotropic elasticity. Lumber is cut into three sections in the flatwise plane and each side member is turned...
Creep Analysis of Composite Steel-Concrete Members with Deformable Connectors
The long-term analysis of composite steel-concrete beams with elastically deformable connectors is presented. The basic integro-differential equation governing the problem is solved by...
Discrete Field Stability Analysis of X-Braced Lattices
The three-dimensional X-braced lattice is used as a compression member in structures ranging from the long span roof of buildings to radio and television antennas. In such cases the design...
Nonlinear Buckling Response of Single Layer Latticed Barrel Vaults
Elastic overall buckling of single layer latticed barrel vault roof structures under static vertical loading is investigated using a fully nonlinear finite element solution procedure and...
Collapse Behavior of Double-Layer Space Truss Grids with Member Buckling
The results of collapse tests of over twenty space truss grids with elastic buckling of members are reviewed. The space truss grids include three types, that is, square-on-square, square-on-diagonal...
Stability Analysis of Stiffened Plates and Shells
A stability analysis of stiffened plates and shells by using degenerated finite elements is presented. The studies are based on a thin shell theory, large deflections, but on an elastic...
Implementation of Elastic Layered Theory for Design of Unbonded Overlays
The U.S. Army and Air Force have implemented the elastic layered theory for design of unbonded overlays for rigid airfield pavements. The procedure allows for design of unbonded overlays...
Nonlinear Analysis of Structural Frameworks Using Supercomputing Techniques
Applications of vectorization and the parallel processing technique of multitasking in the elastic nonlinear analysis of building frameworks are presented. The proposed algorithm is implemented...
Computer Modelling of Comminuting Granular Media
Using generalized continuum mechanics, generalized damage theories for granular materials in comminution processes are proposed. The generalization is accomplished by treating the average...
Analysis of Port Allen Lock in Elastic-Plastic Soil Medium
Incremental finite element analyses using Drucker-Prager plasticity model are applied to study the interaction of Port Allen Lock with its surrounding soil. The analyses not only consider...
Building Separation Rules to Avoid Seismic Pounding
A method to estimate the required separation to preclude pounding between adjacent buildings is presented. It accounts for the effect of yielding on the vibration phase of adjacent buildings....
Modeling Bridge Abutment Stiffness for the Meloland Road Overcrossing
A simplified equivalent spring model representing the dynamic stiffness of a highway bridge abutment system is developed for use in seismic response studies. It is based on linear elastic...
