Metal Truss Plates: Less than Full-Depth Penetration and Shear Buckling
This paper presents the results of two experimental studies on metal truss plates which are used to join members of wood trusses. The first study investigated the effect that less than...
Seismic Strengthening of URM Buildings with Steel Bracing
Unreinforced masonry (URM) buildings with large open fronts are extremely vulnerable to seismic inputs posing serious life safety hazard. Steel bracing systems have been used to upgrade...
Shear Design Guidelines for Polyester Concrete Using Recycled Plastic
Previous research on the shear behavior of steel-reinforced polymer concrete (PC) beams has been very limited and no efficient design procedures have been proposed. In all the previous...
Seismic Response and Retrofitting of Non-Ductile Reinforced Concrete Bridges
The Interstate I5/I605 Separator in Los Angeles County was severely damaged during the October, 1 1987 Whittier Narrows Earthquake. This damage included non-ductile shear failure in the...
Tests of Full-Size Pretensioned AASHTO Beams with Debonded Strands
A summary of an experimental investigation dealing with the effects of strand debonding on the flexure and shear behavior of simply supported pretensioned AASHTO beams with a cast-in-place...
Anchorage of Non-Metallic Prestressing Tendons
Experimental confirmation tests were conducted to evaluate mechanical and epoxy socketed anchors for fiber reinforced plastic (FRP) prestressing tendons. The studies found that a parabolically...
Steady-State Analysis of Buckle Propagation
A novel finite element technique for the analysis of buckle propagation in pipelines is presented. The propagation pressure, propagation profile, the state of stress, and deformation during...
A Generalized Approach to the Local Stability of Stiffened Plates: Part I?Mathematical Formulation
The paper describes a generalized approach for the determination of the buckling stress of stiffened plates under combination of uniform biaxial compression, in-plane bending and shear...
A Generalized Approach to the Local Stability of Stiffened Plates: Part II?Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...
Messeturm Tower: Frankfurt, Germany
A 256 meter (840 feet)tall office tower, currently the tallest building in Europe, has been constructed in Frankfurt Germany. The 7- story structure with 85500 square meter (920,000 square...
Large Deformation Analysis of Lattice Truss Structures Including Hysteretic Material Behavior
A methodology is presented to analyze lattice truss structures including both material and geometric nonlinearities. Modeled member material behavior modes include: buckling, yielding,...
A Shape-Finding Finite Element Analysis for an Equally-Stressed Surface in Membrane Structures
A finite element method is proposed to obtain an equally-stressed surface in a membrane structure, where the displacements and rotations of a membrane are in general finite and nonlinear....
Nonlinear Behavior of Northlight Reinforced Concrete Shells
The behavior of northlight shells is very sensitive to the boundary conditions at the top and bottom edges of the shell. The aim of this paper is to investigate the structural action of...
Punching Shear of Reinforced Concrete Shell Structures
In reinforced concrete shells punching shear failure may take place, if heavy concentrated loads are applied. Such failure is undesirable, since it does not provide adequate warning and...
Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...
Comparison of Eulerian-Lagrangian, Random Walk and Hybrid Methods of Modeling Pollutant Transport
An Eulerian-Lagrangian, a random walk, and a hybrid model were compared in terms of their accuracy and efficiency in simulating two-dimensional pollutant transport. Computer experiments...
Modified Asphalt Binders - How Do They Compare?
This report summarizes some of the research that the US Army Engineer Waterways Experiment Station (WES) has conducted on asphalt modification of airport/airfield pavements. these laboratory...
A Technique to Perform Coupled Consolidation Analysis Using Two Independent Softwares
The consolidation of soils involves two interdependent processes. These are fluid (air and water) flows and the deformation of the soil structure. The two processes tend to be treated...
Automatic, Remote, Multiplexed Geotechnical Measurements with Time Domain Reflectometry (TDR)
Time Domain Reflectometry (TDR) has been employed successfully in geotechnical applications such as monitoring of rock mass deformation in a variety of geometries; however, required operation...
Macroelement Model for Shear Wall Analysis
An efficient modeling scheme for static and dynamic analysis of reinforced concrete shear walls in the inelastic range is presented. The macroelement model of the shear wall is composed...
