Flexural and Shear Behavior of Combined Concrete and Graphite Epoxy Beams
An experimental and analytical study of six graphite composite beams are presented. Four of the beams incorporated a reinforced concrete slab. The composite action and the effect of concrete...
Strength, Behavior and Repair of Masonry Infills
Results of a series of experiments are presented on seismic performance of unreinforced masonry infill panels. The object of the investigation is to examine the loss of out-of-plane strength...
QST Rolled Shapes, a New Generation of HSLA Compression Members
With the development of the Quenching and Self-Tempering (QST) process by the Luxembourg steelmaker ARBED S.A., a new generation of High Strength Low Alloy (HSLA) rolled shapes has become...
The Innovative Concept of Semi-rigid Composite Beam
This paper discusses invention and development of a new type of composite beam called 'Semi-rigid Composite Beam.' This new type of beam is expected to behave better than presently used...
Three-Dimensional Stability Analysis of Carpenter Dam
This paper describes the three-dimensional stability analysis of Carpenter Dam. The presence of keyed construction joints between dam monoliths at Carpenter Dam can significantly affect...
In Situ Testing Performed at Jackson Lake Dam
Jackson Lake Dam was rehabilitated from 1986 to 1988 to increase seismic stability. Final foundation improvements consisted of dynamic compaction and mixed inplace soil cement columns....
Graham Lake Dam Remedial Measures Project
Graham Lake Dam consists of a 550-foot long earth embankment and an 80-foot long concrete spillway. Several concerns were identified during project inspections including limited spillway...
Evaluation of Rehabilitation Needs for Hydraulic-Fill Dam
This paper describes the application of analytical methodologies developed for seismic stability analysis of dams in the western U.S. (particularly the Lower San Fernando Dam in Southern...
Seismic Rehabilitation of Sardis Dam
Extensive subsurface investigation of the embankment dam revealed the existence of a weak layer of silt and soft clay in the original topstratum clay underlaying the upstream shell of...
Seismic Stability Modification Requirements for Pineview Dam
Pineview Dam is located 8 km upstream from Ogden, Utah, and about 8 km from the Wasatch Fault Zone. Preconstruction information and construction records available at the outset of the...
Accelerator for Shotcrete Based Amorphous Calcium Aluminate
The authors developed an accelerator based on amorphous cacium aluminate named NATMIC for shotcrete. In Japan, accelerator based amorphous calcium aluminate are widely used in shotcrete...
The Causticity of Accelerator for Shotcrete and its Impairment on Strength of Shotcrete
How on earth is the toxic and caustic injury of accelerator for shotcrete to operators and animals? How about its impairment on strength of shotcrete? The paper gives some reports and...
Steel Fibre Reinforced Shotcrete Design
There is a need for introducing toughness and ductility in SFRS design. The Japanese Standard introduces the equivalent flexural strength, which characterizes SFRS toughness and allows...
Adapted Actions Taken at Too Low Shotcrete Quality
A tunnel contract specified quality parameters such as: thickness, compressive strength, adhesive strength, bending tensile strength and residual bending tensile strength for fibre reinforced...
Open Channels in Fractures Maintained by Deposition and Erosion of Colloids
Colloids initially suspended in the water in fractures can deposit onto the fracture surfaces, and will partially or fully clog the fracture. The amount of clogging will depend on whether...
Geometric Analyses of Alternative Models of Faulting at Yucca Mountain, Nevada
Realistic cross section tectonic models must be retrodeformable to geologically reasonable pre-deformation states. Furthermore, it must be shown that geologic structures depicted on cross...
Thin-Walled Finite Element for Curved Multicell Box Girders
The generalized Vlasov's thin-walled beam theory was combined with the finite element technique to develop a new curved thin-walled multicell box girder finite element which can model...
A Generalized Three Invariants Cap Model and its Numerical Implementation to Study Soil-Foundation Interaction
This paper presents a modified cap model that is capable of characterizing cyclic stress-strain behavior of soils and describing variation of shear strength along various stress paths...
Study of a Computer System for Evaluation of Bearing Wall Stresses in Structural Planning ? Reasoning by Neural Network
This report proposes a reasoning system for bearing shear wall stresses in the ultimate state by using geometrical data of buildings and shear walls at the initial stage of aseismic structural...
A Numerical Procedure to Compute Bearing Capacity of Shallow Foundations
A simple numerical procedure of calculation of bearing capacity of shallow foundation is proposed. This procedure employs the Terzaghi-Prandtl model of general shear failure. In this paper,...
