Seismic CPT to Measure In-Situ Shear Wave Velocity
A new test, called the seismic cone penetration test (SCPT) is described. A small rugged velocity seismometer has been incorporated into an electronic cone penetrometer. The combination...
Relationships between Shear Wave Velocity and Depth of Overburden
Relationships between in-situ shear wave velocity and depth of overburden have been derived for various Quaternary age soils encountered primarily in Southern California. The geotechnical...
Behavior of Drilled Piers in Layered Soils on Texas Barrier Islands
Twenty-eight full scale load tests and the results of 41 geotechnical studies were analyzed to correlate shear strength interpreted from field and laboratory test data with those derived...
Landslide Hazard Rating for the Oregon Coast Range
The landslide hazard rating system for shallow soils on steep terrain over hard sandstone has three components: ground water response to precipitation, soil shear strength (including root...
Abutment Seepage at Smithville Dam
After initial filling there was concern for the stability of Smithville Dam when higher than anticipated piezometric levels were experienced in the left abutment foundation. Concern heightened...
SRC Elevated Station Structures for New Bullet Trains
SRC Steelframe reinforced concrete structures were utilized on several station buildings for the Japanese National Railways bullet trains. This paper presents an outline of the dimensions...
Recent Developments in Mixed Steel-Concrete Systems
Mixed steel-concrete systems have emerged into a well established new system that can be used as readily as either steel or concrete systems for high-rise buildings. Mixed systems offer...
Bond Stress of Embedded Steel Shapes in Concrete
This paper describes an investigation into the bond stress developed between steel shapes and reinforced concrete when the concrete is lightly stressed. A brief discussion of previous...
Shear Strengths of Concrete-Filled Steel Box Elements
This study evaluated the ultimate strengths as well as the effect of the ultimate composite actions of concrete-filled steel composites under combined bending, shear, and axial forces....
Composite Columns?Design and Examples for Construction
The new German standard DIN 18806, part 1 gives the rules for the design of composite columns. The general method, taking into account all the inhomogeneties of the two materials steel...
Design of Framed Steel Structures with Infill Reinforced Concrete Walls
It is a well-known fact that an infill shear wall in a frame acts as a compressive diagonal strut, giving strength and inflexibility to the frame. Recently the Architectural Institute...
Seismic Capacity Evaluation of SRC Buildings
The Japanese standard for seismic capacity evaluation of existing composite steel and reinforced concrete (SRC) buildings was introduced. As it developed, based on the previously established...
Structural Safety Studies
Structural engineers are most concerned with the safety aspect of structures. The primary objective of structural engineers is to produce structures which are satisfactory in meeting certain...
Measurement and Use of Shear Wave Velocity for Evaluating Dynamic Soil Properties
Geotechnical engineers have recognized in the past decade that shear wave velocity is a basic soil property and have begun to use it to characterize sites for many uses. Most notable has...
Staggered Truss Adapted to High Rise
The 34-floor Nashville Convention Center Hotel required a structural system that would overcome the tendency to vibrate in the wind. The solution was a modified staggered frame truss,...
KEMCOR?A Chemical and Corrosion Resistant Piping System
KEMCOR is a new underground composite pipe system designed for chemical process use in such industries which require a high degree of corrosion resistance to varying concentrations and...
Friction in Hurricane Induced Surges
Bed shear stresses induced by the flowing water are expressed by means of a friction factor for which formulas are developed for: ocean bottom, mangrove fringes and areas, forested areas...
Boundary Shear Stress in a Meandering Channel
Longitudinal and transverse velocity, bed shear, and water surface elevation were studied in a fixed-bed, meandering, laboratory channel with naturally varying, non-prismatic cross sectional...
Safety Aspects of Detroit DPM Station Designs
The Detroit Downtown People Mover (DDPM), currently under construction in the Central Business District of downtown Detroit, offered a unique set of challenges to the architects and engineers...
A New Alternative in Steel Construction?Partially Restrained Connections
Lack of formal training in methods as well as the lack of specific guidelines have limited the understanding and utilization of semi-rigid connection technology. A renewed interest in...
