Deformability of Reinforced Concrete Members
A large volume of test data has been evaluated to establish deformability of reinforced concrete beams, columns, and structural walls in the inelastic range. Experimentally observed deformation...
Structural Resistance of Slabs for Blast Loading
Results from a series of static tests on one-way reinforced concrete slabs are summarized. The slabs were loaded with a uniform pressure and tested to large deflections. Parameters varied...
Cracking the Fire Code
Local building codes specify fire resistance for members in buildings and other structures, and structural engineers select materials and assemblies that have passed a standard fire resistance...
First-Order Estimation of Ko in Sands and Clays
The in-situ horizontal stress coefficient (Ko) is known to be the dominant design parameter controlling the side resistance of deep foundations....
Helical Bearing Plate Foundations for Underpinning
Helical anchor foundations have been used in construction to provide resistance against uplift and compressive loading for structures such as transmission towers, tied walls, pipelines,...
On the Critical Relative Displacement of Pile Shaft and Surrounding Soil
Model pile pull-out tests have been conducted to investigate the characteristics of the critical relative displacement at which the critical pile skin resistance is mobilized. Test results...
Ultimate Capacity of Deep Foundation by a Rigid-Plastic Analysis
This paper is concerned with the determination of the axial ultimate capacity of a rigid pier on the basis of the theory of perfect plasticity. As an application of the upper bound theorem...
Risk Correction Factors for Bearing Capacity Analysis
In this paper bearing capacity correction factors are developed to account for the randomness in the load and soil properties. These are applied to the bearing capacity equation in the...
Bearing Pressure?SPT Correlations for Expanded Base Piles in Sand
Design of enlarged base piles is usually carried out using correlations between SPT N values and point resistance. The results of full scale load tests are used to show that base resistance...
Some Observations on Undrained Side Resistance of Drilled Shafts
A data base of 106 field load tests (65 in uplift and 41 in compression) is used to evaluate the undrained side resistance of drilled shaft foundations. The total stress or alpha (?) method...
Selected Papers from Chinese Journals of Structural Engineering
This book is an initial effort to introduce selected papers from journals published by the China Civil Engineering Society to ASCE membership. The twenty papers in this volume were selected...
Seismic Engineering
Research and Practice
This volume of Seismic Engineering: Research and Practice contains papers from twenty-two sessions of the 1989 ASCE Structures Congress. These papers represent a wide-ranging interest...
Friction Slope Computation for Mathematical Models
The behavior of the energy flow gradient as function of depth and velocity is analyzed for three flow resistance methods. In the paper, the necessary modifications introduced to the methods...
Comparison of
Manning's n values were determined for three stream channels in two complex watersheds in North Mississippi. The study covered a wide range of channel conditions and flow...
Laboratory Analysis of Hyperconcentrations
The physical and kinematic behavior of hyperconcentrations has been reviewed and a summary of recent and past developments in hyperconcentrated flow research is presented. This paper focuses...
A Frictional Resistance Model for the Analysis of Non-Point Source Pollution Processes
This study experimentally investigated the effect of a permeable bed for steady, laminar and smooth turbulent free surface flow on the Darcy-Weisbach friction factor. Flow velocities and...
Effects of Climate Change on Watershed Runoff
This paper examines forecasts of changes in watershed runoff in the Delaware River basin that result from a range of predicted effects of increased atmospheric carbon dioxide (CO2)...
Seven Oaks Dam Outlet Works Design
The U.S. Army Corps of Engineers has completed the preliminary design of the outlet works for the proposed Seven Oaks Dam. The dam is the upstream-most feature of the Corps'...
Design and Operation of a Differential Surge Tank
The differential type of surge tank is more effective in operation than the simple type because it reacts more quickly to load changes of all sizes. The differential tank is also usually...
Subsurface Savings
Less conservatism than usual in designing building foundations is being accepted or demanded by some owners to save money. The article describes four examples of cost-cutting innovations,...
